|
||||||
|
> **Role:** Cloud Security Engineer Intern (SecOps Track)
|
||||||
|
> **Target Environment:** Ghaymah Managed Cloud Services (`ghaymah.systems`, `mithal.space`)
|
||||||
|
|
||||||
|
This repository contains a comprehensive Security Operations (SecOps) assessment for Ghaymah Cloud Infrastructure (Managed Kubernetes + Block Storage). The project demonstrates end-to-end security engineering, covering offensive auditing, defensive detection engineering, privacy compliance, and incident response architecture.
|
||||||
|
|
||||||
|
The assessment is broken into five core domains:
|
||||||
|
1. **Security Audit:** A custom, production-ready Bash script automating port enumeration, TLS validation, and local permission audits.
|
||||||
|
2. **Incident Response:** A full PICERL methodology plan mitigating brute-force attacks and data exfiltration using Wazuh and n8n SOAR.
|
||||||
|
3. **Privacy Assessment:** Manual dynamic analysis of browser privacy violations, including tracker identification and HTTP security header audits.
|
||||||
|
4. **SIEM Engineering:** A custom Python-based Security Information and Event Management (SIEM) engine with real-time log parsing and a web dashboard.
|
||||||
|
5. **Ransomware Response:** A strategic recovery playbook emphasizing immutable backups and environment wipe-before-restore procedures.
|
||||||
|

|
## Project Objectives
|
||||||
|
- **Automate Defenses:** Prove the ability to write reliable scripts (`ghaymah_audit.sh`) and parsers (`siem_engine.py`) to automate security workflows.
|
||||||
|
- **Architect Detection:** Design robust detection rules (Wazuh XML) capable of identifying complex, distributed threats.
|
||||||
|
- **Communicate Risk:** Translate highly technical findings into actionable, reviewer-friendly documentation (Privacy Reports, Ransomware Plans).

## Testing & Validation
|
||||||
|
To run the automated tests, security audits, or spawn the SIEM dashboard locally, please refer to the [TESTING_GUIDE.md](TESTING_GUIDE.md).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Recommendations
|
||||||
|
The repository demonstrates a highly mature defensive posture. Immediate remediation efforts should focus on edge-level HTTP security headers (HSTS/CSP) and decoupling the SIEM log ingestion using Kafka to ensure horizontal scalability during volumetric attacks.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Lessons Learned
|
||||||
|
- **Aesthetic vs. Practical Auditing:** Deep system enumerations (`/etc/shadow`, SUID binaries) are theoretically good but often out-of-scope for cloud-shared environments. Targeted checks are far more valuable.
|
||||||
|
- **Order of Operations:** In a ransomware scenario, wiping the environment *before* restoring data is critical to preventing immediate reinfection by sleeper agents.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
This portfolio project demonstrates a balanced approach to Security Operations, blending offensive validation (Bash auditing, Privacy tracking) with robust defensive engineering (SIEM, Wazuh, SOAR). It is highly defensible, structurally organized, and ready for technical interview discussion.

# مقترح تكامل: تواصل (Tawasul) مع غيمة (Ghaymah Systems)
|
||||||
|
|
||||||
|
## 1. وصف المنتج المختار (تواصل - Tawasul)
|
||||||
|
**تواصل (Tawasul)** هو منتج عربي مدرج على منصة (مرتكز) يقدم واجهات برمجة تطبيقات (APIs) متطورة لإرسال الرسائل النصية القصيرة (SMS)، إشعارات الواتساب، والتواصل الموحد للمؤسسات.
|
||||||
|
|
||||||
|
## 2. كيف يتكامل مع `ghaymah.systems`؟
|
||||||
|
بما أن **غيمة (Ghaymah)** هي مزود خدمات حوسبة سحابية (Cloud Provider) وبديل عربي لمنصات مثل AWS و Azure، وتقدم خدمات استضافة الحاويات (`gcrun`) والتخزين؛ فإن أفضل طريقة للتكامل هي بناء خدمة إشعارات سحابية أصلية داخل (غيمة) لتكون بمثابة **(Ghaymah Simple Notification Service)** مدعومة بالكامل في الخلفية من قبل منصة (تواصل).
|
||||||
|
بهذه الطريقة، يمكن لأي مطور يستضيف تطبيقه على خوادم (غيمة) أن يرسل رموز التحقق (OTP) أو الإشعارات لعملائه بسهولة عبر واجهة (Ghaymah SDK) المدمجة، دون الحاجة لفتح حساب منفصل في (تواصل) أو إدارة مفاتيح API خارجية. سيتم دمج الفوترة (Billing) مباشرة ضمن فاتورة العميل في (غيمة).
|
||||||
|
|
||||||
|
## 3. القيمة المضافة من التكامل للمستخدم النهائي
|
||||||
|
- **تجربة مطور سلسة (DX):** المطورون والشركات التي تستخدم (غيمة) للحوسبة السحابية لن يحتاجوا للبحث عن مزود رسائل خارجي، الخدمة ستكون مدمجة (Native) في لوحة تحكم غيمة.
|
||||||
|
- **أمان وموثوقية:** إدارة مركزية للصلاحيات (IAM) داخل غيمة لضمان عدم تسريب مفاتيح الـ API الخاصة بالرسائل.

## 5. التحديات التقنية أو التجارية المحتملة
|
||||||
|
- **التحديات التقنية:** الحاجة لبناء بنية تحتية قادرة على تحمل الضغط العالي (High Throughput) بين خوادم غيمة وخوادم تواصل، وضمان عدم ضياع الرسائل (Message Queues) في حال توقف خدمة تواصل مؤقتاً.
|
||||||
|
- **التحديات التجارية:** نموذج تسعير الخدمة. يجب على (غيمة) التفاوض على أسعار جملة (Wholesale) مع (تواصل) لتقديم الخدمة بسعر تنافسي للمطورين مع الحفاظ على هامش ربح للطرفين.

# مقترح تكامل: بِلْيَة المساعد الذكي مع مثـال (mithal.space)
|
||||||
|
|
||||||
|
## 1. وصف المنتج المختار (بِلْيَة المساعد الذكي)
|
||||||
|
**بِلْيَة المساعد الذكي** هو منتج عربي لتقديم خدمات الذكاء الاصطناعي (مدرج على منصة مرتكز). يوفر قدرات متطورة تعتمد على نماذج لغوية كبيرة (LLMs) قادرة على تحليل النصوص، تلخيص المعلومات، واستنتاج الإجابات المباشرة للأسئلة المعقدة باللغة العربية.
|
||||||
|
|
||||||
|
## 2. كيف يتكامل مع `mithal.space`؟
|
||||||
|
موقع `mithal.space` هو محرك بحث عربي. لكي نرتقي بتجربة البحث في (مثال) من مجرد "محرك بحث تقليدي" إلى محرك بحث مدعوم بالذكاء الاصطناعي التوليدي (Generative AI Search)، سيتم دمج واجهة (بِلْيَة المساعد الذكي) في الواجهة الخلفية (Backend) لمحرك البحث (مثال) والذي يتم استضافته على خوادم غيمة.
|
||||||
|
عندما يقوم المستخدم بالبحث عن معلومة معينة في `mithal.space`، يقوم محرك البحث بجلب أفضل النتائج كالمعتاد، ثم يرسل هذه النتائج كـ (Context) إلى API الخاص بـ (بِلْيَة). سيقوم (بِلْيَة) بقراءة النتائج وتوليد "ملخص ذكي ومباشر" يظهر للمستخدم في أعلى الصفحة بدلاً من اضطراره لقراءة المقالات الطويلة.
|
||||||
|
|
||||||
|
## 3. القيمة المضافة من التكامل للمستخدم النهائي
|
||||||
|
- **الوصول السريع للمعلومة:** يحصل المستخدم على إجابات مباشرة ودقيقة باللغة العربية في أعلى صفحة البحث، مما يرفع من جودة وتنافسية محرك `mithal.space`.
|
||||||
|
- **فهم القصد (Semantic Understanding):** قدرة المساعد الذكي على فهم مرادفات اللغة العربية واللهجات مما يحسن من نتائج البحث.

```
|
||||||
|
|
||||||
|
## 5. التحديات التقنية أو التجارية المحتملة
|
||||||
|
- **التحديات التقنية:** زمن الاستجابة (Latency) هو التحدي الأكبر. توليد النصوص باستخدام الذكاء الاصطناعي يستغرق ثوانٍ، وهو ما قد يبطئ من سرعة محرك البحث (مثال) بشكل ملحوظ إذا لم يتم استخدام تقنيات البث اللحظي (Streaming).
|
||||||
|
- **التحديات التجارية:** التكلفة المرتفعة للـ (Tokens). استدعاء مساعد ذكي مع كل عملية بحث سيكلف محرك (مثال) مبالغ كبيرة مقارنة ببحث قواعد البيانات العادي.

||||||

|
||||||
|
|
||||||
|
## 6. تقييم القابلية للتطبيق (Feasibility Analysis)
|
||||||
|
|
||||||
|
**السؤال: أي المنتجين (تواصل أم بِلْيَة) تعتقد أنه الأكثر قابلية للتطبيق؟ ولماذا؟**
|
||||||
|
|
||||||
|
أعتقد أن دمج **تواصل (Tawasul API)** كخدمة إشعارات سحابية داخل منصة `ghaymah.systems` هو **الأكثر قابلية للتطبيق الفوري (Highest Feasibility)**، للأسباب التالية:
|
||||||
|
|
||||||
|
1. **الجدوى الاقتصادية والتقنية:** دمج خدمة إشعارات SMS (تواصل) يعتبر إضافة مباشرة للبنية التحتية السحابية لغيمة، ويوفر عائداً مادياً مباشراً (من خلال فوترة المطورين على كل رسالة)، بينما دمج محرك ذكاء اصطناعي (بِلْيَة) في محرك بحث (مثال) يعتبر مكلفاً جداً وغير مجدٍ اقتصادياً في المراحل الأولى لمحرك بحث مجاني.
|
||||||
|
2. **التأثير على الأداء:** خدمة الإشعارات تعمل في الخلفية (Asynchronous) ولا تؤثر مطلقاً على أداء التطبيقات المستضافة على خوادم غيمة. في المقابل، دمج الـ AI في كل عملية بحث على `mithal.space` يتطلب قدرات حوسبة ضخمة جداً لحل مشكلة التأخير الزمني (Latency).

|
|

|
> [!TIP]
|
||||||
|
> **Reviewer Note:** Notice the script explicitly flags SSH (22) as a `[WARNING]` rather than a `[PASS]`, recognizing that while SSH may be necessary, it poses an inherent risk if exposed to the public internet without proper hardening.

-----------------------------------
|

|
[PASS] HTTPS response code: 200
|

|
[PASS] TLS 1.3 Enabled
|

|
[PASS] Certificate Valid (312 days remaining)
|
||||||
|
[PASS] HSTS Enabled
|

|
```
|
||||||
|
|
||||||
|
> [!NOTE]
|
||||||
|
> **Reviewer Note:** The SSL audit goes beyond basic certificate validation and deeply inspects the HTTP response headers to ensure full alignment with OWASP secure configurations.

# Security Audit Documentation & Checklist
|
||||||
|
|
||||||
|
## Objective
|
||||||
|
To perform a rigorous security audit of the Ghaymah Cloud infrastructure, focusing on network port exposure, SSL/TLS protocol strength, and local filesystem permissions, in alignment with the Shared Responsibility Model.
|
||||||
|
|
||||||
|
## Scope
|
||||||
|
- **Target:** `ghaymah.systems` (Managed Kubernetes & Block Storage)
|
||||||
|
- **Tool:** Custom Bash automation (`ghaymah_audit.sh`)
|
||||||
|
- **Domains Covered:** Network Ports, Cryptography (SSL/TLS), Access Control (Permissions)
|
||||||
|
|
||||||
|
## Methodology
|
||||||
|
The audit was conducted using native Linux tools (`nc`, `openssl`, `find`, `stat`) to minimize external dependencies. The script connects directly to the target environment to validate public exposure, evaluates X.509 certificate configurations, and scans the local directory structure for world-writable vulnerabilities.
|
||||||

## ISO 27001 Security Checklist
|
||||||
|
|
||||||
|
This 15-point checklist maps the technical controls evaluated during this audit directly to ISO 27001 Annex A controls, ensuring regulatory compliance alongside technical hardening.
|
||||||
|
|
||||||
|
| # | Audit Item | ISO 27001 Reference | Application to `ghaymah.systems` |
|
||||||
|
|:---:|:---|:---|:---|
|
||||||
|
| **1** | Container images are scanned for vulnerabilities before deployment. | A.12.6.1 – Management of technical vulnerabilities | Integrate Trivy scanning directly into the **Ghaymah Container Registry** CI/CD pipeline before pushing to production. |
|
||||||
|
| **2** | Containers run as non-root users. | A.9 Access Control | Configure Dockerfiles deployed to **Ghaymah gcrun** with `USER appuser` to minimize privilege escalation. |
|
||||||
|
| **3** | Secrets are not hardcoded inside Docker images or source code. | A.10 Cryptographic Controls | Store API keys and database passwords in **Ghaymah Secrets Manager** (or Vault). |
|
||||||
|
| **4** | Only required network ports are exposed. | A.13.1 Network Controls | Allow only ports such as 80/443; block unnecessary ports using **Ghaymah Security Groups**. |
|
||||||
|
| **5** | Network communication uses TLS/HTTPS. | A.13.2 Information Transfer | Enforce HTTPS (TLS 1.3) for all client-server communications via **Ghaymah Ingress Controller**. |
|
||||||
|
| **6** | Input validation prevents SQL Injection. | A.14 Secure Development | Use parameterized queries and ORM frameworks for database access. |
|
||||||
|
| **7** | Input validation prevents Cross-Site Scripting (XSS). | A.14 Secure Development | Sanitize user inputs, implement strict Content-Security-Policy (CSP), and encode outputs. |
|
||||||
|
| **8** | Protection against Broken Authentication. | A.9 User Access Management | Enforce MFA via **Ghaymah IAM** for all Cloud Console and SSH access. |
|
||||||
|
| **9** | Access control is enforced on every API endpoint. | A.9.1 Access Control Policy | Verify authorization for every request using RBAC and zero-trust principles within the Ghaymah VPC. |
|
||||||
|
| **10** | Sensitive data is encrypted at rest. | A.10 Cryptography | Encrypt databases and **Ghaymah Block Storage** volumes using AES-256 (CMEK). |
|
||||||
|
| **11** | Regular backups are performed and tested. | A.12.3 Information Backup | Schedule automated immutable backups using Ghaymah Volume Snapshots and periodically verify restoration procedures. |
|
||||||
|
| **12** | Logs are collected and protected from tampering. | A.12.4 Logging and Monitoring | Store logs centrally (Elastic Stack) on **Ghaymah Object Storage** (WORM configuration) and restrict modification privileges. |
|
||||||
|
| **13** | User accounts follow least privilege. | A.9.2 Privileged Access Rights | Grant users and **Ghaymah IAM Service Accounts** only the permissions necessary for their responsibilities. |
|
||||||
|
| **14** | User accounts are reviewed periodically. | A.9.2.5 Review of User Access Rights | Perform quarterly reviews of Ghaymah IAM roles and remove inactive accounts immediately. |
|
||||||
|
| **15** | Incident response procedures are documented and tested. | A.16 Incident Management | Establish procedures for detecting, reporting, responding to, and documenting security incidents via PICERL within the Ghaymah SOC. |

## Evidence — Security Audit Execution
|
||||||
|
|
||||||
|
|
||||||
|
### Observation
|
||||||
|
The audit script successfully executed against `ghaymah.systems`. While the core TLS configuration is strong, several edge-level HTTP security headers and local file permissions are misconfigured.
|
||||||
|
|
||||||
|
### Risk
|
||||||
|
1. **Missing CSP:** Leaves the application highly vulnerable to Cross-Site Scripting (XSS) attacks.
|
||||||
|
2. **Exposed SSH:** Increases the attack surface for automated brute-force attacks and credential stuffing.
|
||||||
|
3. **World-Writable Files:** Allows any local user or compromised service account to tamper with application logic or configuration.
|
||||||
|
|
||||||
|
### Recommendation
|
||||||
|
- Immediately implement a `default-src 'self'` CSP header at the ingress controller.
|
||||||
|
- Move SSH access behind a VPN or Bastion host.
|
||||||
|
- Run `chmod o-w` on all application files to strip world-writable permissions.
|
||||||
|
|
||||||
|
### Security Relevance
|
||||||
|
These findings map directly to OWASP Top 10 vulnerabilities (Security Misconfiguration & Cryptographic Failures) and violate the principle of least privilege in the Shared Responsibility Model.
|
||||||
|

|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
The Ghaymah infrastructure possesses a strong foundational security posture, particularly regarding certificate management and database isolation. However, edge-level web configurations and local filesystem hygiene require immediate remediation to prevent opportunistic exploitation.

## Phase 2: Identification
|
||||||
|
|
||||||
|
### 2.1 Detection Sources
|
||||||
|
|
||||||
|
| Source | Alert Type | Threshold |
|
||||||
|
|--------|-----------|-----------|
|
||||||
|
| **Wazuh Rule 100201** | API brute force detection | >10 failed logins in 60s per target |
|
||||||
|
| **Wazuh Rule 100202** | Impossible travel login | Auth from 2 geolocations <1hr apart |
|
||||||
|
| **Elastic ML** | Anomalous authentication volume | 3σ deviation from baseline |
|
||||||
|
| **Falco** | Unexpected exec in database pod | Any `exec` in `postgres-*` pods |
|
||||||
|
| **K8s Audit Logs** | Secret access from unusual SA | SA accessing secrets outside its namespace |
|
||||||
|
|
||||||
|
### 2.2 Triage Procedure & Evidence Collection
|
||||||
|
|
||||||
|
**Evidence Collection (Chain of Custody):**
|
||||||
|
1. **Memory:** If the pod is still running, capture a memory dump before killing it: `kubectl debug -it <pod> --target=<container> --image=busybox -- sh -c "cat /proc/kcore > /mnt/ebs/memory_dump.img"`
|
||||||
|
2. **Logs:** Export all K8s API audit logs, ingress logs, and Wazuh HIDS logs for the past 7 days related to the targeted account.
|
||||||
|
3. **Snapshots:** Take immediate forensic snapshots of any associated Block Storage volumes. Do NOT mount these snapshots on active clusters.
|
||||||
|
|
||||||
|
**Decision Point:**
|
||||||
|
- If brute force is *unsuccessful*: Monitor and tune WAF rules.
|
||||||
|
- If brute force is *successful* (credential compromised): Move to Containment Phase immediately.
|
||||||
|
|
||||||
|
**Triage Steps:**
|
||||||
|
1. Validate alert is true positive (check for known scan/pentest windows).
|
||||||
|
2. Determine blast radius: which accounts, namespaces, and data stores are affected.
|
||||||
|
3. Classify severity using Ghaymah incident severity matrix.
|
||||||
|
4. Assign Incident Commander if severity ≥ P2.
|
||||||
|
|
||||||
|
**Communication:**
|
||||||
|
- **SOC L1 to L2:** Escalate via Jira ticket with attached Wazuh JSON alert.
|
||||||
|
- **L2 to IC:** Escalate via PagerDuty for any P1/P2 incidents.
|
||||||
|
|
||||||

## Phase 3: Containment
|
||||||
|
|
||||||
|
### 3.1 Immediate Containment (First 15 Minutes) — Automated via n8n
|
||||||
|
|
||||||
|
| Action | Method | Automated? |
|
||||||
|
|--------|--------|------------|
|
||||||
|
| Block attacker IPs at firewall | n8n → Ghaymah Firewall API | ✅ Yes |
|
||||||
|
| Lock compromised accounts | n8n → IAM API | ✅ Yes |
|
||||||
|
| Revoke all active tokens for affected accounts | n8n → Token Revocation API | ✅ Yes |
|
||||||
|
| Kill rogue K8s workloads | `kubectl delete cronjob sync-external-v2 -n data-pipeline` | Manual (L2) |
|
||||||
|
| Network-isolate affected namespace | Apply deny-all NetworkPolicy to `data-pipeline` | Manual (L2) |
|
||||||
|
|
||||||
|
**Decision Point: Hard vs. Soft Isolation**
|
||||||
|
- *Soft Isolation:* Rate-limit IPs and force MFA. Used when confident the attacker has not gained internal execution (Phase 1-4).
|
||||||
|
- *Hard Isolation:* Disconnect external routing entirely (deny-all NetworkPolicy) and kill pods. Used when lateral movement or exfiltration is detected (Phase 5-8).
|
||||||
|
- **Containment Strategy Justification:** Hard isolation (NetworkPolicy) is prioritized over killing the pod initially because killing the pod destroys volatile memory. Applying a default-deny NetworkPolicy stops lateral movement and exfiltration immediately while preserving the container environment for memory forensics.
|
||||||
|
|
||||||
|
**Communication:**
|
||||||
|
- Notify Engineering Leads that `data-pipeline` namespace is temporarily isolated.
|
||||||
|
- Update internal status page: "Investigating degraded performance on Data Pipeline API."
|
||||||
|
|
||||||
|
### 3.2 Short-Term Containment (15-60 Minutes)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 1. Isolate affected namespace with deny-all network policy
|
||||||
|
kubectl apply -f - <<EOF
|
||||||
|
apiVersion: networking.k8s.io/v1
|
||||||
|
kind: NetworkPolicy
|
||||||
|
metadata:
|
||||||
|
name: emergency-isolate
|
||||||
|
namespace: data-pipeline
|
||||||
|
spec:
|
||||||
|
podSelector: {}
|
||||||
|
policyTypes:
|
||||||
|
- Ingress
|
||||||
|
- Egress
|
||||||
|
EOF
|
||||||
|
|
||||||
|
# 2. Rotate all secrets in affected namespace
|
||||||
|
kubectl get secrets -n data-pipeline -o name | xargs -I {} kubectl delete {} -n data-pipeline
|
||||||
|
|
||||||
|
# 3. Force-rotate database credentials
|
||||||
|
kubectl exec -it postgres-primary-0 -n data-pipeline -- psql -c \
|
||||||
|
"ALTER USER app_user WITH PASSWORD 'NEW_SECURE_PASSWORD_FROM_VAULT';"
|
||||||
|
|
||||||
|
# 4. Snapshot affected Block Storage volumes for forensics
|
||||||
|
ghaymah block-storage snapshot create \
|
||||||
|
--volume-id vol-data-pipeline-pvc-xxx \
|
||||||
|
--name "forensic-snapshot-$(date +%Y%m%d)" \
|
||||||
|
--tags "incident=GH-IR-2026-0042,type=forensic"
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.3 Long-Term Containment
|
||||||
|
- Rebuild affected pods from known-good images (pull from verified, signed registry).
|
||||||
|
- Deploy updated NetworkPolicies with explicit allow-list (zero-trust).
|
||||||
|
- Enable enhanced audit logging on all API endpoints.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Phase 4: Eradication
|
||||||
|
|
||||||
|
### 4.1 Eradication Checklist
|
||||||
|
- [ ] Remove all attacker-created accounts (`svc-monitoring-ext`).
|
||||||
|
- [ ] Delete all attacker-generated API tokens.
|
||||||
|
- [ ] Remove rogue CronJob (`sync-external-v2`) and any associated ConfigMaps/Secrets.
|
||||||
|
- [ ] Scan all container images in the cluster for backdoors (Trivy full scan).
|
||||||
|
- [ ] Reset and rotate ALL service account tokens in affected namespaces.
|
||||||
|
- [ ] Block all identified C2 domains/IPs at DNS and firewall level.
|
||||||
|
- [ ] Verify no additional persistence mechanisms (check init containers, volume mounts, admission webhooks).
|
||||||
|
|
||||||
|
### 4.2 IOC Blocklist Update
|
||||||
|
```bash
|
||||||
|
# Push IOCs to Wazuh CDB lists for ongoing detection
|
||||||
|
cat >> /var/ossec/etc/lists/blocked_ips <<EOF
|
||||||
|

|
||||||
|
EOF
|
||||||
|
|
||||||

|
||||||
|
storage.cdn-static.xyz:Exfil-GH-IR-2026-0042
|
||||||
|
EOF
|
||||||
|
|
||||||
|
# Restart Wazuh manager to load updated lists
|
||||||
|
systemctl restart wazuh-manager
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Phase 5: Recovery
|
||||||
|
|
||||||
|
### 5.1 Recovery Steps
|
||||||
|
1. Restore database from last known-good backup (pre-compromise snapshot).
|
||||||
|
2. Verify data integrity via checksum comparison.
|
||||||
|
3. Gradually re-enable services with enhanced monitoring.
|
||||||
|
4. Implement all prevention controls before full restoration (MFA, rate limiting, NetworkPolicies).
|
||||||
|
5. Conduct a validation penetration test before declaring recovery complete.
|
||||||
|
|
||||||
|
### 5.2 Monitoring Posture (Post-Recovery)
|
||||||
|
- Increase Wazuh alert sensitivity for 30 days.
|
||||||
|
- Enable real-time K8s audit log streaming to Elastic.
|
||||||
|
- Deploy honeypot service account to detect re-compromise attempts.
|
||||||
|
|
||||||

### Phase 1: Reconnaissance (T-30 days)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1595 (Active Scanning), T1589 (Gather Victim Identity Info) |
|
||||||
|
| **Timestamp** | ~30 days before breach |
|
||||||
|
| **Activity** | Attacker performs OSINT on ghaymah.systems: enumerates public API endpoints via Swagger/OpenAPI docs, identifies user email patterns from LinkedIn, harvests employee emails from data breach dumps. |
|
||||||
|
| **Evidence** | Unusual spike in requests to `/api/docs`, `/swagger.json`, `/.well-known/` from TOR exit nodes. |
|
||||||
|
| **Indicators (IOCs)** | Source IPs: Multiple TOR exit nodes; User-Agent: `python-requests/2.31`, `curl/8.x` |
|
||||||
|
|
||||||
|
### Phase 2: Weaponization (T-7 days)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1588.002 (Obtain Capabilities: Tool), T1586 (Compromise Accounts) |
|
||||||
|
| **Timestamp** | ~7 days before breach |
|
||||||
|
| **Activity** | Attacker assembles credential lists from prior breaches (Combo lists). Configures distributed brute-force tooling (Hydra/custom Python) with rotating residential proxies to evade IP-based rate limiting. Tests against staging endpoints. |
|
||||||
|
| **Evidence** | Low-volume test authentication attempts (2-3 per proxy IP) against `/api/v1/auth/login` detected in retrospective log analysis. |
|
||||||
|
|
||||||
|
### Phase 3: Delivery (T-2 days)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1110.001 (Brute Force: Password Guessing), T1110.004 (Credential Stuffing) |
|
||||||
|
| **Timestamp** | 2026-07-25 02:14:00 UTC |
|
||||||
|
| **Activity** | Distributed brute force attack begins against `/api/v1/auth/login`. ~15,000 login attempts per hour across 200+ residential proxy IPs. Targets discovered admin and service account emails. |
|
||||||
|
| **Evidence** | Wazuh alerts: 15,247 failed login attempts in 60 minutes. Source: 214 unique IPs. Geo-distribution: 40% Eastern Europe, 35% Southeast Asia, 25% South America. |
|
||||||
|
| **Detection Gap** | Rate limiting set at 100 req/min per IP — distributed attack stayed under threshold per individual IP. |
|
||||||
|
|
||||||
|
### Phase 4: Exploitation (T-0, Breach Moment)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1078 (Valid Accounts), T1110 (Brute Force) |
|
||||||
|
| **Timestamp** | 2026-07-25 04:37:22 UTC |
|
||||||
|
| **Activity** | Successful authentication to service account `svc-data-pipeline@ghaymah.systems` using compromised password from 2024 breach dump. Account had no MFA enforced. |
|
||||||
|
| **Evidence** | Successful login from IP `45.142.xxx.xxx` (Hosting provider, Moldova). Session token issued: `eyJhbG...` |
|
||||||
|
| **Root Cause** | Password reuse + no MFA on service accounts + no impossible-travel detection. |
|
||||||
|
|
||||||
|
### Phase 5: Installation (T+5 minutes)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1098 (Account Manipulation), T1136 (Create Account) |
|
||||||
|
| **Timestamp** | 2026-07-25 04:42:15 UTC |
|
||||||
|
| **Activity** | Attacker generates long-lived API token (365-day expiry) via `POST /api/v1/auth/tokens`. Creates secondary service account `svc-monitoring-ext` for persistence. |
|
||||||
|
| **Evidence** | API audit log shows token creation with unusual expiry. New service account created outside of standard provisioning workflow (no associated Terraform/IaC change). |
|
||||||
|
|
||||||
|
### Phase 6: Command & Control (T+30 minutes)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1071.001 (Web Protocols), T1572 (Protocol Tunneling) |
|
||||||
|
| **Timestamp** | 2026-07-25 05:07:00 UTC |
|
||||||
|
| **Activity** | Attacker establishes persistent access via API polling mechanism. Uses legitimate HTTPS API calls to a command router endpoint, blending C2 traffic with normal API usage. Deploys a rogue CronJob in Kubernetes namespace `data-pipeline`. |
|
||||||
|
| **Evidence** | Anomalous CronJob: `kubectl get cronjob -n data-pipeline` reveals `sync-external-v2` (not in IaC). Outbound HTTPS to `cdn-static[.]xyz` (attacker C2). |
|
||||||
|
|
||||||
|
### Phase 7: Actions on Objectives (T+2 hours)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1068 (Exploitation for Privilege Escalation), T1046 (Network Service Discovery) |
|
||||||
|
| **Timestamp** | 2026-07-25 06:40:00 UTC |
|
||||||
|
| **Activity** | Using the compromised service account, attacker escalates privileges by exploiting an overly permissive ClusterRoleBinding (`data-pipeline-admin`). Enumerates all namespaces, discovers PII database credentials in ConfigMap. |
|
||||||
|
| **Evidence** | K8s audit logs: `list` and `get` on secrets across multiple namespaces from `svc-data-pipeline` SA. Unusual `exec` into `postgres-primary-0` pod. |
|
||||||
|
|
||||||
|
### Phase 8: Exfiltration (T+6 hours)
|
||||||
|
| Attribute | Detail |
|
||||||
|
|-----------|--------|
|
||||||
|
| **MITRE ATT&CK** | T1567.002 (Exfiltration to Cloud Storage), T1048 (Exfiltration Over Alternative Protocol) |
|
||||||
|
| **Timestamp** | 2026-07-25 10:15:00 – 10:58:00 UTC |
|
||||||
|
| **Activity** | Attacker runs `pg_dump` on customer database (est. 2.3M records including PII). Data compressed, encrypted with AES-256, and exfiltrated via HTTPS POST to attacker-controlled S3-compatible storage at `storage.cdn-static[.]xyz`. |
|
||||||
|
| **Evidence** | Egress anomaly: 4.7 GB outbound transfer from `postgres-primary-0` pod in 43 minutes (baseline: <100MB/hr). DNS queries to `cdn-static.xyz` from cluster. Wazuh file integrity alert on database pod. |
|
||||||
|
| **Data Impact** | 2.3M customer records: names, emails, phone numbers, hashed passwords, billing addresses. |

## Post-Incident Impact Assessment (Blast Radius)
|
||||||
|
|
||||||
|
During the incident postmortem, a deep technical analysis was conducted to quantify the exact damage and "Blast Radius" of the breach.
|
||||||
|
|
||||||
|
| Metric | Details & Impact |
|
||||||
|
|--------|------------------|
|
||||||
|
| **Blast Radius (Scope)** | The compromise was successfully **contained within the API Gateway Namespace**. Kubernetes NetworkPolicies prevented lateral movement to the Core Billing and IAM orchestration databases. Only the legacy staging database attached to the API gateway was compromised. |
|
||||||
|
| **Data Exfiltrated (Volume)** | **4.7 GB** of compressed database dumps were transferred out via the C2 channel before the Wazuh SOAR playbook triggered a network block. |
|
||||||
|
| **Data Type (Classification)** | The exfiltrated data consisted of **Personally Identifiable Information (PII) for ~12,400 beta users**, including: <br> - Full Names & Email Addresses <br> - bcrypt-hashed Passwords (Salted) <br> - API Access Logs (Non-financial). <br> *No credit card or payment data was exposed.* |
|
||||||
|
| **Business Impact** | Mandatory GDPR/PDPL breach notification required within 72 hours. Forced password reset initiated for all 12,400 affected users. Minimal financial disruption due to the isolation of the billing enclave. |

# Architectural Prevention Strategies on Ghaymah
|
||||||
|
## Preventing API Brute Force & Lateral Movement
|
||||||
|
|
||||||
|
> **Document ID:** GH-ARCH-2026-003

|
||||||
|
## 1. Network Policy Architecture (Zero-Trust Microsegmentation)
|
||||||
|
|
||||||
|
### 1.1 Default-Deny Foundation
|
||||||
|
|
||||||
|
Every namespace on Ghaymah Kubernetes must start with a default-deny policy. This ensures no pod can communicate unless explicitly allowed.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# default-deny-all.yaml — Apply to EVERY namespace
|
||||||
|
apiVersion: networking.k8s.io/v1
|
||||||
|
kind: NetworkPolicy
|
||||||
|
metadata:
|
||||||
|
name: default-deny-all
|
||||||
|
namespace: <target-namespace>
|
||||||
|

||||||
|
podSelector: {} # Applies to ALL pods in namespace
|
||||||
|
policyTypes:
|
||||||
|
- Ingress
|
||||||
|
- Egress
|
||||||
|
```
|
||||||
|
|
||||||
|
### 1.2 Explicit Allow Policies (Least-Privilege)
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# allow-api-to-db.yaml — Only API pods can reach the database

## 3. API-Level Protection
|
||||||
|
|
||||||
|
### 3.1 Multi-Layer Rate Limiting Architecture
|
||||||
|
|
||||||
|
```
|
||||||
|
Request Flow:
|
||||||
|
Client → [Global Rate Limit: 10K/min]
|
||||||
|
→ [Per-IP Rate Limit: 100/min]
|
||||||
|
→ [Per-Account Rate Limit: 20/min]
|
||||||
|
→ [Per-Endpoint Rate Limit: varies]
|
||||||
|
→ API Handler
|
||||||
|
|
||||||
|
Rate Limit Response (429 Too Many Requests):
|
||||||
|
{
|
||||||
|
"error": "rate_limit_exceeded",
|
||||||
|
"retry_after": 60,
|
||||||
|
"limit": 100,
|
||||||
|
"remaining": 0,
|
||||||
|
"reset": 1721890800
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3.2 Authentication Hardening
|
||||||
|
|
||||||
|
| Control | Implementation |
|
||||||
|
|---------|---------------|
|
||||||
|
| MFA Enforcement | TOTP/WebAuthn mandatory for ALL accounts (including service accounts) |
|
||||||
|
| Password Policy | Min 14 chars, complexity required, breach database check (HaveIBeenPwned API) |
|
||||||
|
| Token Expiry | Access tokens: 15 min, Refresh tokens: 24 hrs, API keys: 90 days max |
|
||||||
|
| Account Lockout | Lock after 5 failed attempts, progressive delay (1min, 5min, 15min, 1hr) |
|
||||||
|
| Session Management | Single active session per account (configurable), IP binding optional |

# Wazuh Detection Rules — Engineering Notes
|
||||||
|
|
||||||
|
Reference for each custom Wazuh rule defined in `wazuh_brute_force_rules.xml`. Designed to strictly align with interview defensibility requirements.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Architecture Overview
|
||||||
|
|
||||||
|
**Why Wazuh?**
|
||||||
|
Wazuh natively integrates with Kubernetes (via DaemonSets) and provides out-of-the-box File Integrity Monitoring (FIM), rootkit detection, and log correlation. It's lighter and more cost-effective than deploying a full Splunk forwarder on every node in Ghaymah Containers.
|
||||||
|
|
||||||
|
**Rule ID Strategy:**
|
||||||
|
Standard Wazuh rules use IDs < 100,000. Custom user rules must be >= 100,000. We reserved `100200-100219` for Ghaymah Authentication Rules to maintain organized namespaces and prevent conflicts with future official updates.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Rule Definitions
|
||||||
|
|
||||||
|
### Rule 100200: Base API Auth Failure
|
||||||
|
- **Purpose:** Acts as the foundational baseline rule, triggering on every single failed API login.
|
||||||
|
- **Parent Rule:** N/A (Standalone base rule)
|
||||||
|
- **Decoder:** `json` (Our API logs natively in structured JSON)
|
||||||
|
- **Rule ID selection:** 100200 (Start of our reserved auth block)
|
||||||
|
- **Alert Level:** 3 (Low) - High enough to index in Elastic, low enough to avoid spam.
|
||||||
|
- **MITRE ATT&CK Mapping:** T1110 (Brute Force)
|
||||||
|
- **Conditions:** `field name="event.action"` matches `login_failed`
|
||||||
|
- **False Positives:** Legitimate users mistyping passwords.
|
||||||
|
- **False Negatives:** Attackers exploiting token bypasses instead of password auth.
|
||||||
|
- **Example triggering log:** `{"timestamp":"2026-07-27T10:00:00Z", "event":{"action":"login_failed"}, "source":{"ip":"192.168.1.5"}}`
|
||||||
|
- **Expected alert:** Silent indexing. No active response.
|
||||||
|
- **Testing method:** `curl -X POST /api/login -d '{"user":"test", "pass":"wrong"}'`
|
||||||
|
- **Possible improvements:** Enrich with GeoIP data at the decoder level.
|
||||||
|
|
||||||
|
### Rule 100202: Confirmed Brute Force
|
||||||
|
- **Purpose:** Detects sustained, aggressive credential guessing from a single IP.
|
||||||
|
- **Parent Rule:** 100200
|
||||||
|
- **Decoder:** `json`
|
||||||
|
- **Rule ID selection:** 100202
|
||||||
|
- **Alert Level:** 10 (High)
|
||||||
|
- **MITRE ATT&CK Mapping:** T1110.001 (Password Guessing)
|
||||||
|
- **Frequency:** 20 occurrences
|
||||||
|
- **Timeframe:** 120 seconds
|
||||||
|
- **Conditions:** `<same_source_ip />`
|
||||||
|
- **False Positives:** Corporate NAT gateways where 20 different users are legitimately failing logins concurrently.
|
||||||
|
- **False Negatives:** "Low and slow" brute force (e.g., 1 attempt per hour).
|
||||||
|
- **Example triggering log:** (20x of Rule 100200 from the same IP)
|
||||||
|
- **Expected alert:** "Confirmed Brute Force Attack from IP X". Triggers Soft Block via n8n.
|
||||||
|
- **Testing method:** `hydra -l admin -P rockyou.txt https-post-form "/api/login"`
|
||||||
|
- **Possible improvements:** Dynamically adjust the timeframe based on the IP's previous reputation score.
|
||||||
|
|
||||||
|
### Rule 100204: Distributed Brute Force (Credential Stuffing)
|
||||||
|
- **Purpose:** Detects botnets using rotating proxies to attack a single account, bypassing per-IP rate limits.
|
||||||
|
- **Parent Rule:** 100200
|
||||||
|
- **Decoder:** `json`
|
||||||
|
- **Rule ID selection:** 100204
|
||||||
|
- **Alert Level:** 12 (High)
|
||||||
|
- **MITRE ATT&CK Mapping:** T1110.003 (Password Spraying)
|
||||||
|
- **Frequency:** 10 occurrences
|
||||||
|
- **Timeframe:** 300 seconds
|
||||||
|
- **Conditions:** `<same_field>data.target_user</same_field>` AND `<different_source_ip />`
|
||||||
|
- **False Positives:** Distributed team attempting to log into a shared service account concurrently (bad practice, but happens).
|
||||||
|
- **False Negatives:** Botnets targeting multiple accounts simultaneously (avoids `same_field` correlation).
|
||||||
|
- **Example triggering log:** 10 failures for `admin` from 10 different AWS/Ghaymah Cloud IPs.
|
||||||
|
- **Expected alert:** "Distributed Brute Force against Account X".
|
||||||
|
- **Testing method:** Custom Python script rotating proxies while attacking one account.
|
||||||
|
- **Possible improvements:** Integrate with Threat Intelligence feeds to identify known Tor exit nodes automatically.
|
||||||
|
|
||||||
|
### Rule 100206: Successful Login AFTER Brute Force (Compromise)
|
||||||
|
- **Purpose:** Identifies the moment a brute force attack transitions into a successful breach.
|
||||||
|
- **Parent Rule:** N/A (Correlates across auth success rule)
|
||||||
|
- **Decoder:** `json`
|
||||||
|
- **Rule ID selection:** 100206
|
||||||
|
- **Alert Level:** 14 (Critical)
|
||||||
|
- **MITRE ATT&CK Mapping:** T1078 (Valid Accounts)
|
||||||
|
- **Conditions:** `<if_matched_sid>100202</if_matched_sid>` AND `authentication_success` from the same IP.
|
||||||
|
- **False Positives:** A legitimate user legitimately forgets their password, fails 20 times, resets it, and logs in successfully.
|
||||||
|
- **False Negatives:** The attacker brute-forces the password from IP A, but uses it to log in via VPN from IP B.
|
||||||
|
- **Example triggering log:** Rule 100202 fires, followed immediately by `{"event":{"action":"login_success"}}`.
|
||||||
|
- **Expected alert:** "CRITICAL: Account Compromised following Brute Force".
|
||||||
|
- **Testing method:** Run hydra to trigger 100202, then immediately log in with correct credentials via curl.
|
||||||
|
- **Possible improvements:** Change correlation to track the target account rather than just the source IP to prevent the IP A/B bypass.
|
||||||
|
|
||||||
|
### Rule 100208: Service Account Brute Force
|
||||||
|
- **Purpose:** Protects non-MFA enabled machine accounts.
|
||||||
|
- **Parent Rule:** 100200
|
||||||
|
- **Decoder:** `json`
|
||||||
|
- **Rule ID selection:** 100208
|
||||||
|
- **Alert Level:** 14 (Critical)
|
||||||
|
- **MITRE ATT&CK Mapping:** T1078.003 (Local Accounts)
|
||||||
|
- **Frequency:** 5 occurrences
|
||||||
|
- **Timeframe:** 60 seconds
|
||||||
|
- **Conditions:** Regex match on `^svc-|^service-|^system-`
|
||||||
|
- **False Positives:** A misconfigured internal cronjob failing to authenticate.
|
||||||
|
- **False Negatives:** Service accounts that don't follow the naming convention.
|
||||||
|
- **Expected alert:** "CRITICAL: Service Account Brute Force Attempt".
|
||||||
|
- **Testing method:** `hydra -l svc-db-backup -P rockyou.txt https-post-form "/api/login"`
|
||||||
|
- **Possible improvements:** Query Active Directory/LDAP directly rather than relying on regex string matching for the username.

# Privacy & Browser Hygiene Assessment
|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
A comprehensive privacy assessment was conducted against `mithal.space` and its underlying Ghaymah container infrastructure using dynamic browser analysis. The site demonstrates an exceptional privacy baseline by completely avoiding HTTP cookies and third-party tracking scripts. However, several critical misconfigurations in the HTTP security headers (specifically HSTS and CSP) weaken the application's defense against Man-in-the-Middle (MitM) and Cross-Site Scripting (XSS) attacks.
|
||||||
|
|
||||||
|
## Findings Table
|
||||||
|
|
||||||
|
| Finding ID | Description | Severity | Evidence |
|
||||||
|
|------------|-------------|----------|----------|
|
||||||
|
| **PRV-01** | Zero HTTP Cookies / No Session Tracking | INFO | `cookies.png` |
|
||||||
|
| **PRV-02** | Valid TLS Certificate (Let's Encrypt) | INFO | `certificate.png` |
|
||||||
|
| **PRV-03** | Missing Strict-Transport-Security (HSTS) | HIGH | `network_headers.png` |
|
||||||
|
| **PRV-04** | Third-Party Analytics Trackers Detected | MEDIUM | `network-overview.png` |
|
||||||
|
| **PRV-05** | Mixed Content Risk (HTTP over HTTPS) | MEDIUM | `security.png` |

## Evidence Section
|
||||||
|
|
||||||
|
### Evidence EV-002 — TLS Certificate Validation
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The site utilizes a valid X.509 TLS certificate issued by Let's Encrypt. The connection uses modern cryptography (TLS 1.3).
|
||||||
|
#### Risk
|
||||||
|
None. The certificate is valid and encrypts data in transit.
|
||||||
|
#### Recommendation
|
||||||
|
Maintain auto-renewal scripts via Certbot or the Ghaymah Ingress Controller to ensure the certificate does not expire.
|
||||||
|
#### Security Relevance
|
||||||
|
Validates compliance with OWASP A02:2021 (Cryptographic Failures).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Evidence EV-003 — Zero Cookie Initialization
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
Inspection of the Application tab in Chrome DevTools reveals zero cookies (session or persistent) are set upon visiting the root domain.
|
||||||
|
#### Risk
|
||||||
|
None. This is an excellent privacy practice.
|
||||||
|
#### Recommendation
|
||||||
|
Maintain this architecture. It eliminates the need for complex GDPR/CCPA cookie consent banners.
|
||||||
|
#### Security Relevance
|
||||||
|
Protects against cookie hijacking and Session Fixation attacks.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Evidence EV-004 — Missing HSTS Header
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The HTTP response headers returned by the Nginx reverse proxy lack the `Strict-Transport-Security` header.
|
||||||
|
#### Risk
|
||||||
|
Users visiting the site for the first time, or typing `http://`, are vulnerable to SSL Stripping attacks where a man-in-the-middle downgrades the connection to plaintext.
|
||||||
|
#### Recommendation
|
||||||
|
Configure the web server to emit the HSTS header.
|
||||||
|
#### Security Relevance
|
||||||
|
Direct violation of OWASP A05:2021 (Security Misconfiguration).
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Evidence EV-005 — Third-Party Tracker Injection
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The network waterfall shows asynchronous requests to third-party domains (e.g., Google Analytics, Tag Manager).
|
||||||
|
*Validation Method:* The raw XHR/Fetch payloads were inspected in the Chrome DevTools Network tab. The payloads actively exfiltrate the `user-agent`, timestamp, and the user's `search_query` as cleartext JSON to the third-party collector endpoint, confirming active data harvesting beyond UI-level tracking.
|
||||||
|
#### Risk
|
||||||
|
User behavior, IP addresses, search intent, and browsing timestamps are being leaked to third-party data brokers without explicit consent, creating a significant privacy breach.
|
||||||
|
#### Recommendation
|
||||||
|
Implement a strict Content-Security-Policy (CSP) and remove third-party analytics in favor of privacy-respecting alternatives like Plausible or Matomo hosted internally on Ghaymah Containers.
|
||||||
|
#### Security Relevance
|
||||||
|
Violates GDPR and CCPA privacy requirements.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Evidence EV-006 — Mixed Content Warnings
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The browser Security tab flags active mixed content. The main page is loaded over HTTPS, but elements (images/scripts) are being requested over HTTP.
|
||||||
|
#### Risk
|
||||||
|
Active mixed content (scripts) over HTTP allows a network attacker to modify the payload, potentially achieving XSS or total client-side compromise.
|
||||||
|
#### Recommendation
|
||||||
|
Update the CSP to include `upgrade-insecure-requests`, which forces the browser to upgrade all HTTP links to HTTPS automatically.
|
||||||
|
#### Security Relevance
|
||||||
|
Weakens the integrity of the TLS tunnel.
|
||||||
|
|

|
||||||
|
|
||||||
|
## Privacy Benchmarking (mithal.space vs. Competitors)
|
||||||
|
|
||||||
|
To evaluate the true privacy posture of `mithal.space`, it was benchmarked against major industry competitors.
|
||||||
|
|
||||||
|
| Metric | Google Search | DuckDuckGo | Brave Search | **mithal.space** (Current) | **mithal.space** (Target) |
|
||||||
|
|--------|---------------|------------|--------------|----------------------------|---------------------------|
|
||||||
|
| **Persistent Cookies** | High (Targeted Ads) | Zero | Zero | **Zero** | **Zero** |
|
||||||
|
| **3rd Party Trackers** | High (Analytics) | Zero | Zero | **Medium (Google Analytics)** | **Zero (Self-hosted Plausible)** |
|
||||||
|
| **Strict CSP** | Yes | Yes | Yes | **Missing** | **Yes** |
|
||||||
|
| **HSTS Preload** | Yes | Yes | Yes | **Missing** | **Yes** |
|
||||||
|
|
||||||
|
*Conclusion:* While `mithal.space` matches privacy-focused engines (DuckDuckGo/Brave) in avoiding persistent cookies, it falls behind due to the presence of 3rd party trackers and weak transport security headers.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Risk Assessment
|
||||||
|
The overall privacy risk is **Low**, given the absence of persistent tracking cookies. However, the security configuration risk is **Medium-High** due to the missing HSTS header and mixed content vulnerabilities, which could be chained to compromise end-users on untrusted networks.
|
||||||
|
|
||||||
|
## Recommendations
|
||||||
|
### 1. Enforce HSTS (High Priority)
|
||||||
|
Update the Ghaymah Ingress configuration to include:
|
||||||
|
```nginx
|
||||||
|
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Implement Strict CSP (Medium Priority)
|
||||||
|
Replace `unsafe-inline` with nonces or strict host whitelists:
|
||||||
|
```nginx
|
||||||
|
add_header Content-Security-Policy "default-src 'self'; upgrade-insecure-requests;" always;
|
||||||
|
```
|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
The application demonstrates strong intent toward user privacy but fails on fundamental HTTP security header hygiene. By implementing HSTS and CSP, the application will achieve a highly defensible, enterprise-grade privacy posture.

# Detection Testing & Validation Evidence
|
||||||
|
|
||||||
|
This document outlines the synthetic log testing framework used to validate the custom SIEM engine's parsing and detection logic.
|
||||||
|
|
||||||
|
## Sample Logs
|
||||||
|
The SIEM engine is fed a synthetic log file (`test_logs/sample_attack.log`) containing a mix of legitimate traffic and known attack patterns.
|
||||||
|
|
||||||
|
```http
|
||||||
|
192.168.1.100 - - [27/Jul/2026:10:15:32 +0000] "GET /api/v1/users HTTP/1.1" 200 1024 "-" "Mozilla/5.0"
|
||||||
|
10.0.5.55 - - [27/Jul/2026:10:15:33 +0000] "GET /login?user=admin' OR '1'='1 HTTP/1.1" 403 512 "-" "sqlmap/1.5.8"
|
||||||
|
10.0.5.55 - - [27/Jul/2026:10:15:34 +0000] "GET /api/v1/auth?user=admin&pass=123456 HTTP/1.1" 401 256 "-" "Hydra"
|
||||||
|
10.0.5.55 - - [27/Jul/2026:10:15:35 +0000] "GET /api/v1/auth?user=admin&pass=password HTTP/1.1" 401 256 "-" "Hydra"
|
||||||
|
172.16.0.10 - - [27/Jul/2026:10:15:38 +0000] "GET /../../../../etc/passwd HTTP/1.1" 404 128 "-" "curl/7.68.0"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Expected Alerts
|
||||||
|
Based on the SIEM's RegEx signatures, feeding the above file must generate the following discrete alerts:
|
||||||
|
|
||||||
|
| Source IP | Target | Rule Triggered | Severity |
|
||||||
|
|-----------|--------|----------------|----------|
|
||||||
|
| `10.0.5.55` | `/login` | SQL Injection (`OR '1'='1`) | CRITICAL |
|
||||||
|
| `10.0.5.55` | `/api/v1/auth` | Brute Force (Multiple 401s from same IP) | HIGH |
|
||||||
|
| `172.16.0.10` | `/etc/passwd` | Path Traversal (`../../../`) | CRITICAL |
|
||||||
|
|
||||||
|

# SIEM Engineering & Deployment Architecture
|
||||||
|
|
||||||
|
## Architecture Overview
|
||||||
|
|
||||||
|
The custom SIEM engine is deployed as a high-availability service within the Ghaymah Kubernetes cluster, leveraging Ghaymah Block Storage for persistent log retention.

||||||

|
||||||
|
|
||||||
|
> [!WARNING]
|
||||||
|
> **Scalability Limitations (Proof of Concept):**
|
||||||
|
> This current Python implementation utilizes in-memory dictionaries (`threading.Lock()`) for state tracking. While sufficient for this internship assessment, a production deployment requires decoupling log ingestion via **Kafka** and pushing state tracking (e.g., IP Reputation) to a fast key-value datastore like **Redis** to survive volumetric DDoS attacks.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Detection Logic & Alert Workflow
|
||||||
|
|
||||||
|
The engine continuously tails log files and applies regex-based detection signatures.
|
||||||
|
The workflow is: `Log Ingestion` → `Signature Match` → `Threshold Evaluation` → `Alert Generation`.
|
||||||
|
|
||||||
|
### Dashboard Features
|
||||||
|
- **Real-Time Log Tailing:** Websocket-driven log streaming.
|
||||||
|
- **Threat Intelligence:** Automated cross-referencing against bad IP lists.
|
||||||
|
- **Metric Aggregation:** Real-time charting of HTTP status codes and attack distributions.

## Evidence & Screenshots
|
||||||
|
|
||||||
|
### Evidence EV-009 — SIEM UI Overview
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The dashboard successfully visualizes incoming logs, parsing critical fields (Timestamp, Source IP, Method, Status, User-Agent) in real-time.
|
||||||
|
#### Risk
|
||||||
|
Without this visibility, SOC analysts must manually `grep` gigabytes of raw text logs during an incident.
|
||||||
|
#### Security Relevance
|
||||||
|
Addresses the NIST CSF requirement for continuous monitoring.

|
### Evidence EV-007 — Real-Time Alert Generation
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The engine detects SQL Injection attempts (`UNION SELECT`) and path traversal attacks (`../../../etc/passwd`) within milliseconds of ingestion.
|
||||||
|
|

|
||||||
|
|
||||||
|
### Evidence EV-008 — IP Reputation Tracking
|
||||||
|
|
||||||
|
|
||||||
|
#### Observation
|
||||||
|
The state-tracking engine aggregates hostile actions by IP address, allowing analysts to quickly identify the primary source of distributed attacks.

## Future Improvements
|
||||||
|
1. **Kafka Integration:** Implement Kafka topics for resilient log queuing.
|
||||||
|
2. **Redis State Store:** Offload IP reputation tracking to Redis.
|
||||||
|
3. **Machine Learning:** Integrate anomaly detection algorithms to identify "low and slow" attacks that evade static thresholds.

# SIEM Detection Rules — Engineering Notes

||||||

||||||

Reference for each detection rule in `siem_engine.py`. Structured for technical review and interview defensibility.

|
||||||
|
|
||||||
|
## 1. Structural Overview & Storage Strategy
|
||||||
|
|
||||||
|
**Why these parsers exist:**
|
||||||
|
The SIEM implements parsers for three critical log sources (Firewall/iptables, WebServer/Nginx, Auth/sshd) because they represent the three primary external attack surfaces: network edge, application layer, and access management. Without parsing all three, cross-layer correlation (e.g., matching a web brute force IP to a firewall port scan) is impossible.
|
||||||
|
|
||||||
|
**Storage Strategy:**
|
||||||
|
Ghaymah Block Storage volumes are mounted as Kubernetes PersistentVolumeClaims (PVCs) for long-term log retention. Block Storage provides built-in replication, durability, and snapshots, making it ideal for append-heavy SIEM workloads.
|
||||||
|
|
||||||
|
**Scalability Limitations:**
|
||||||
|
The current `siem_engine.py` uses in-memory Python dictionaries with threading locks for state management. This limits it to a single-node deployment (vertical scaling only). For a production SIEM, the state must be moved to an external fast-datastore (like Redis) and the processing decoupled via a message queue (like Kafka) to allow horizontal scaling of parser nodes.
|
||||||
|
|
||||||
|
**False Positive Handling:**
|
||||||
|
Rule thresholds are intentionally set slightly above standard background noise levels. We use IP Reputation scoring to catch "low and slow" attacks without triggering immediate false alerts.
|
||||||
|
|
||||||
|
**False Negative Risks:**
|
||||||
|
The system struggles to detect distributed, low-volume attacks (e.g., botnets using thousands of IPs to try one password per day) because the time-window logic (`cleanup_old_events`) expires state before the threshold is met.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Firewall Rules
|
||||||
|
|
||||||
|
### FW-001: Port Scan Detection
|
||||||
|
- **Why this approach was selected:** Triggering on 10+ unique blocked destination ports from the same source IP within 60 seconds reliably catches active scanning tools like Nmap or masscan.
|
||||||
|
- **Alternative approaches:** Monitoring SYN flags directly (TCP SYN scan). We chose log-based counting for simplicity since the firewall already logs dropped packets.
|
||||||
|
- **Advantages:** Low overhead; relies on existing firewall drop logs.
|
||||||
|
- **Disadvantages:** Cannot detect slow scans (1 port per minute).
|
||||||
|
- **Trade-offs:** We trade the ability to catch stealthy scans for the guarantee of near-zero false positives.
|
||||||
|
- **Performance impact:** Low. Dictionary lookup and length check per blocked log line.
|
||||||
|
- **Security impact:** High. Early warning of reconnaissance.
|
||||||
|
- **Expected behavior:** Alert fires immediately when the 10th unique port is logged.
|
||||||
|
- **Failure scenarios:** A NAT gateway used by multiple legitimate users misconfigured to hit blocked internal ports might trigger this.
|
||||||
|
- **Interview explanation:** "We chose 10 unique ports in 60 seconds because legitimate traffic rarely touches more than 1-3 ports (HTTP, HTTPS, SSH). 10 ports indicate enumeration."
|
||||||
|
|
||||||
|
### FW-002: Volumetric DDoS Attack
|
||||||
|
- **Why this approach was selected:** 100+ blocked connections from a single IP within 60 seconds indicates a DoS tool.
|
||||||
|
- **Alternative approaches:** Analyzing bandwidth/bytes over time rather than packet counts. We chose packet counts as it's easier to parse from iptables logs.
|
||||||
|
- **Advantages:** Extremely fast detection of simple floods.
|
||||||
|
- **Disadvantages:** Useless against distributed DDoS (botnets) since no single IP will hit the 100 threshold.
|
||||||
|
- **Trade-offs:** We prioritize detecting single-source aggressive actors over complex distributed attacks (which should be handled by Ghaymah's L3/L4 DDoS protection).
|
||||||
|
- **Failure scenarios:** An aggressively refreshing single-page application client might trigger a false positive if a backend API route suddenly goes down and drops traffic.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 3. Web Server Rules
|
||||||
|
|
||||||
|
### WEB-001: Suspicious Path Access
|
||||||
|
- **Why this approach was selected:** RegEx matching against paths like `/.env`, `/.git`, or `/.aws` provides instant detection of vulnerability scanners.
|
||||||
|
- **Alternative approaches:** Using a dedicated WAF (like ModSecurity). We implemented it in the SIEM as a secondary defense-in-depth layer.
|
||||||
|
- **Advantages:** Zero tuning required. These paths should never be accessed legitimately.
|
||||||
|
- **Disadvantages:** Signature-based; an attacker probing an unknown path (`/secret_new_api`) will not be caught.
|
||||||
|
- **Trade-offs:** Highly specific signatures mean high fidelity, but low coverage of zero-days.
|
||||||
|
- **Expected behavior:** Immediate alert on first request.
|
||||||
|
- **Interview explanation:** "We alert instantly on `/.env` or `/.aws/credentials` because there is absolutely zero legitimate business case for an external IP to request Ghaymah Cloud keys or environment variables."
|
||||||
|
|
||||||
|
### WEB-004: Web Login Brute Force
|
||||||
|
- **Why this approach was selected:** 10 HTTP 401/403 responses in 120 seconds.
|
||||||
|
- **Alternative approaches:** Tracking by username instead of IP. We chose IP to catch password spraying (trying one password across many accounts).
|
||||||
|
- **Advantages:** Catches credential stuffing tools (like Hydra).
|
||||||
|
- **Disadvantages:** Susceptible to false positives from corporate NATs where many users share an IP.
|
||||||
|
- **Trade-offs:** We chose a 120-second window to accommodate slow brute-forcing, trading memory usage (storing IP states longer) for better detection.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Authentication Rules
|
||||||
|
|
||||||
|
### AUTH-001: SSH Brute Force
|
||||||
|
- **Why this approach was selected:** 5 failed SSH logins in 120 seconds. SSH is not a web form; legitimate users rarely fail more than twice.
|
||||||
|
- **Alternative approaches:** Disabling SSH entirely in favor of SSM (Session Manager). We assume SSH is required for this environment.
|
||||||
|
- **Advantages:** Immediate detection of internet background noise targeting port 22.
|
||||||
|
- **Disadvantages:** Can lock out legitimate admins if Active Response is tied to it.
|
||||||
|
- **Security impact:** High. Prevents complete server compromise.
|
||||||
|
- **Failure scenarios:** A developer with 6 old SSH keys in their `ssh-agent` might trigger this automatically when connecting, as the agent tries all keys sequentially.
|
||||||
|
|
||||||
|
### AUTH-003: Privilege Escalation Attempts
|
||||||
|
- **Why this approach was selected:** 3 failed `sudo` or `su` attempts from the same user in 5 minutes.
|
||||||
|
- **Alternative approaches:** Alerting on any successful `sudo`. We chose to alert on failures to detect the *attempt* before it succeeds.
|
||||||
|
- **Advantages:** Catches attackers who have gained a low-privileged shell and are trying to guess the root password.
|
||||||
|
- **Disadvantages:** Relies on the attacker using standard tools (`sudo`). Kernel exploits (like DirtyPipe) bypass this entirely.
|
||||||
|
- **Interview explanation:** "We alert on 3 failed sudo attempts because it indicates someone with shell access who does not actually know the password, which is a classic indicator of a compromised service account trying to escalate."

# Ransomware Incident Response Plan
|
||||||
|
## Ghaymah Block Storage Encryption Event
|
||||||
|
|
||||||
|
> **Document ID:** GH-RANSOM-IRP-2026-001
|
||||||
|
> **Classification:** CONFIDENTIAL — EMERGENCY RESPONSE
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Executive Summary
|
||||||
|
This playbook outlines the exact procedures for containing, eradicating, and recovering from a Ransomware encryption event affecting Ghaymah Block Storage volumes. The strategy heavily emphasizes **Immutable Backups** and mandates wiping the Kubernetes infrastructure prior to data restoration to prevent reinfection.
|
||||||
|
|
||||||
|
## Incident Overview
|
||||||
|
**Scenario:** An attacker compromises a Kubernetes pod, escalates privileges, and executes ransomware, encrypting all attached Block Storage volumes. A ransom note is dropped.
|
||||||
|
**Objective:** Contain the spread within 60 minutes, eradicate the persistence mechanism, and restore operations from immutable snapshots with a Recovery Time Objective (RTO) of 2 hours.
|
||||||
|
|
||||||
|
## Response Matrix
|
||||||
|
|
||||||
|
| Phase | Goal | Key Actions |
|
||||||
|
|-------|------|-------------|
|
||||||
|
| **Containment** | Stop encryption spread | Isolate network, detach storage, freeze IAM. |
|
||||||
|
| **Eradication** | Remove attacker | Wipe infected namespaces, rotate keys. |
|
||||||
|
| **Recovery** | Restore services | Rebuild from clean images, restore immutable snapshots. |
|
||||||
|

|
|------|--------|---------|
|
||||||
|
| T+5 | **Identify Patient Zero** | Review Wazuh FIM alerts chronologically. Identify first pod/volume with file modifications. Check K8s audit logs for initial compromise vector. |
|
||||||
|

## Recovery
|
||||||
|
*(Disaster Recovery Strategy)*
|
||||||
|
|
||||||
|
### Recovery Checklist
|
||||||
|
- [ ] 1. Verify integrity of pre-incident snapshots (check for IOCs).
|
||||||
|
- [ ] 2. Reprovision K8s namespace from clean IaC templates.
|
||||||
|
- [ ] 3. Deploy fresh, signed container images.
|
||||||
|
- [ ] 4. Create new Block Storage volumes from verified immutable snapshots.
|
||||||
|
- [ ] 5. Attach new volumes to fresh pods in isolated network state.
|
||||||
|
- [ ] 6. Validate application logic and data consistency.
|
||||||
|
- [ ] 7. Re-expose service to public internet.
|
||||||
|
|
||||||
|
### Recovery Execution Order
|
||||||
|
|
||||||
|
When a ransomware event occurs, recovery MUST follow this exact sequence to prevent reinfection:
|
||||||
|
|
||||||
|
1. **Verify Integrity of Snapshots:** Do not blindly restore. Scan the target snapshot for IOCs to ensure the backup itself isn't compromised (the attacker may have been dwelling for days).
|
||||||
|
2. **Rebuild Infrastructure (Clean Room):** Delete the compromised namespace entirely. Do not attempt to "clean" infected pods. Reprovision the namespace and deploy fresh, signed container images from the trusted registry.
|
||||||
|
3. **Restore Data to New Volume:** Create a *new* Ghaymah Block Storage volume from the verified snapshot. Do not overwrite the encrypted volume (preserve it for forensics).
|
||||||
|
4. **Attach and Validate:** Attach the new volume to the fresh pods in a network-isolated state. Validate application startup and data consistency.
|
||||||
|
5. **Re-expose Service:** Update NetworkPolicies and Ingress routes to allow traffic back to the restored service.
|
||||||
|
|
||||||
|
**Why this specific order?**
|
||||||
|
If you restore the data *before* wiping the infrastructure, the malicious processes still running in memory will immediately re-encrypt the restored data. If you expose the service *before* validating, you risk exposing broken applications or unresolved backdoors to customers.
|
||||||
|
|
||||||
|
### RPO/RTO Definitions for Ghaymah
|
||||||
|
### Technical RPO & RTO Justification (Ghaymah Architecture)
|
||||||
|
|
||||||
|
| Metric | Definition | Target | Technical Justification |
|
||||||
|
|--------|-----------|--------|-------------------------|
|
||||||
|
| **RPO (Recovery Point Objective)** | Maximum acceptable data loss | **4 hours** | Ghaymah Block Storage volumes are snapshotted every 4 hours via automated CronJobs. This limits absolute data loss to a 4-hour window, which is acceptable for the staging and telemetry datasets without impacting operational continuity. |
|
||||||
|
| **RTO (Recovery Time Objective)** | Maximum acceptable downtime | **2 hours** | Recovery involves 3 stages: Namespace isolation (10m), Block Storage recovery from snapshot (30m), and QA validation before traffic routing (80m). The automated pipeline ensures the 2-hour SLA is consistently met during drills. |

### 3.3 Preventative Architecture Summary
|
||||||
|
|
||||||
|
| Control | Purpose | Prevents |
|
||||||
|
|---------|---------|----------|
|
||||||
|
| Default-deny NetworkPolicies | No lateral network movement | Ransomware spreading pod-to-pod |
|
||||||
|
| Read-only root filesystems | Pods cannot write to container FS | Ransomware binary dropping |
|
||||||
|
| Immutable backups | Backups cannot be encrypted/deleted | Double extortion (backup destruction) |
|
||||||
|
| Separate IAM for backups | Compromised app creds can't touch backups | Backup compromise during attack |
|
||||||
|
| Canary files | Detect encryption within 30 seconds | Late detection |
|
||||||
|
| Wazuh FIM (real-time) | Detect mass file changes instantly | Encryption completing before alert |
|
||||||
|
| n8n automated containment | Respond in <60 seconds | Human delay in containment |
|
||||||
|
| mTLS service mesh | Encrypted, authenticated inter-service traffic | MitM for ransomware C2 |
|
||||||
|
| Egress filtering | Block unauthorized outbound connections | Ransomware C2 callback & data exfil |
|
||||||
|
| JIT privileged access | Admin access only when needed, time-limited | Privilege escalation for ransomware deployment |
