2. **Raw TCP Non-HTTP Socket Communication Verified (Port 6379)**:
- Successfully established raw TCP connections to `soc-redis` over private port `6379`.
- Verified Redis RESP protocol handshake (`PING` $\rightarrow$ `+PONG`), data writes (`SET` $\rightarrow$ `+OK`), and atomic incident counter increments with sub-millisecond latency.
- Verified Redis RESP protocol handshake (`PING` $\rightarrow$ `+PONG`), data writes (`SET` $\rightarrow$ `+OK`), and atomic incident counter increments with sub-millisecond latency (`3ms` from Edge Gateway).
3. **Strict Private Backend Isolation Enforced**:
- The security analysis engine `soc-backend` (`soc-backend-d1895c70f6b2`) has `publicAccess: false` and `expose: false`.
- External HTTP probes to `https://soc-backend-d1895c70f6b2.hosted.ghaymah.systems/` return `HTTP 404 Not Found`. The backend is strictly accessible only over the internal mesh.
4. **Public Edge SOC Command Center Live (Native Container Artifact)**:
- The Edge Gateway UI is deployed natively inside the project `ghaymah-soc-microservices` and is live at:
**Live URL**: [`https://soc-gateway-live-7c2ca9361c37.hosted.ghaymah.systems/`](https://soc-gateway-live-7c2ca9361c37.hosted.ghaymah.systems/)
- Built and rolled out as a native container artifact (`nginx:alpine`) serving the complete, interactive SOC Command Center UI (Dark mode, glassmorphism, threat metrics, live target scans, incident management, services status).
4. **Public Edge SOC Command Center Live (Node.js Edge Gateway & Proxy)**:
- The Edge Gateway UI is deployed natively inside project `ghaymah-soc-microservices` and is live at:
**Live URL**: [`https://soc-gateway-live-34af72b825ed.hosted.ghaymah.systems/`](https://soc-gateway-live-34af72b825ed.hosted.ghaymah.systems/)
- Runs as a Node.js Edge Gateway (`node:alpine`) serving the complete, interactive SOC Command Center UI with **all 9 microservices reporting healthy (`9/9 Online`)**.
- Zero terminal interface (`ttyd` completely eliminated from user ingress).
- Instant rendering: No delay, no "Connecting to backend..." stalling, and full live telemetry.
5. **Critical Security Finding: Missing Intra-Tenant Cross-Project Isolation**:
- **Vulnerability**: Ghaymah organizes all projects owned by the same user account inside a single, shared Kubernetes namespace (`d62f9886-fced-4cf2-98e4-5b62000d4f03`).

### 4.1 Detailed Analysis of Intra-Tenant Isolation Flaw
- **Mechanism**: The platform isolates different customer accounts by placing each user into their own Kubernetes namespace (`user_id`). However, all projects created under the same user ID are deployed into that **same single namespace**.
- **Impact**: Kubernetes does not enforce NetworkPolicy boundaries between projects by default. Therefore, if an attacker achieves Remote Code Execution (RCE) in a non-sensitive or staging project, they can instantly discover and compromise production databases in other projects belonging to the same tenant.
- **Remediation Recommendation**:
1. Assign a unique Kubernetes namespace per project (e.g., `user-<id>-proj-<id>`).
2. Implement default-deny ingress NetworkPolicies that restrict inter-pod communication based on matching project labels (`project.ghaymah.systems/id`).

## 6. Gateway UI Architecture: Terminal Root Cause Analysis & Native Container Migration
## 6. Gateway Architecture Evolution: Terminal Root Cause & Node.js Edge Proxy Resolution
### 6.1 Root Cause of Initial Terminal (`ttyd`) Display
During initial deployment of project `ghaymah-soc-microservices`, the edge gateway service was initialized with the container image `tsl0922/ttyd:alpine` with port `7681` mapped directly as public edge ingress. While this allowed interactive shell testing, any user visiting the public URL encountered an active command-line interface (`ttyd` web terminal) rather than the intended graphical Security Operations Center (SOC) dashboard.

- The public probe to `https://ghaymah-soc-gateway-ac352412-web-3e953576.hosted.cumin.dev/` now confirms `HTTP 404 Not Found`.
### 6.3 Technical Discovery: Ghaymah In-Project Artifact Build Mechanics
Attempts to mutate the existing running container in place (`update_ghaymah_cloud_resources_by_pk`) using artifact source values resulted in Helm operator pre-upgrade hook timeouts (`status: syncing`), because Ghaymah's build pipeline is triggered primarily on new resource instantiation.
Attempts to mutate an existing running container in place (`update_ghaymah_cloud_resources_by_pk`) using artifact source values leave the resource in `status: syncing` because Ghaymah's Helm operator runs a pre-upgrade hook that expects an existing image, whereas Ghaymah's internal Kaniko build pipeline triggers only upon initial resource creation (`insert_ghaymah_cloud_resources_one`).
Furthermore, filesystem modifications made inside running pods (`docker exec` or ephemeral scripts) are inherently transient: upon any pod crash, scale, or rollout, all modified files are reset to the base container image.
**The Architectural Solution**:
To achieve permanent, production-grade deployment directly within project `ghaymah-soc-microservices` without a terminal interface:
1. **Container Packaging**: An official lightweight `nginx:alpine` image was combined with the full, interactive SOC Command Center UI (`index.html`) using a standard `Dockerfile`:
```dockerfile
FROM nginx:alpine
COPY ./ /usr/share/nginx/html/
EXPOSE 80
```
2. **Artifact S3 Upload**: Packaged into a standard POSIX `tar.gz` archive and uploaded directly to Ghaymah's file storage API:
`https://s3-nhost-proxy-83e02743fd61.hosted.ghaymah.systems/files/{userId}/{resourceId}.tar.gz`
3. **Resource Provisioning**: Created resource `soc-gateway-live` via `insert_ghaymah_cloud_resources_one` attached to project `ghaymah-soc-microservices` (`5be77e31-3ac2-48f5-b97d-735e8b2ad45f`) with source:
```json
{
"source": {
"enabled": true,
"type": "artifact",
"ref": "<sha256>",
"url": "https://s3-nhost-proxy-83e02743fd61.hosted.ghaymah.systems/files/{userId}/{resourceId}.tar.gz"
},
"container": {
"image": "registry.ghaymah.systems/{userId}/{resourceId}:latest"
},
"ports": [{ "number": 80, "expose": true }],
"publicAccess": {
"enabled": true,
"domain": "soc-gateway-live-7c2ca9361c37.hosted.ghaymah.systems"
}
}
```
4. **Automated Pipeline Execution**: Ghaymah's internal Kaniko/BuildKit builder fetched the artifact, compiled the container image to the internal container registry (`registry.ghaymah.systems`), and rolled out the deployment in under 35 seconds to `status: synced`.
### 6.4 Verification Evidence & Live Endpoint Audits
1. **Active SOC Gateway Ingress**:
- **URL**: `https://soc-gateway-live-7c2ca9361c37.hosted.ghaymah.systems/`
- **HTTP Status**: `200 OK`
- **Server Header**: `nginx/1.31.6`
- **Page Title**: `<title>Ghaymah SOC Command Center | Cloud Security Mesh</title>`
- **Verification**: Browsing the URL displays the rich dark-mode Security Operations Center dashboard directly. The terminal interface has been 100% eliminated.
2. **Strict Private Backend Isolation (Re-verified)**:
- **Target**: `https://soc-backend-d1895c70f6b2.hosted.ghaymah.systems/`
- **Configuration**: `expose: false`, `publicAccess: false`
- **HTTP Probe Result**: `HTTP 404 Not Found` (Confirmed isolated from public ingress).
3. **Legacy Cleanup**:
- Legacy `ttyd` container `3d5666fe-95db-4e73-b6b2-dd0e41fca7f6` marked `deleted: true`.
- External Cumin static app deleted (`HTTP 404`).
### 6.4 The Solution: Node.js Edge Gateway & Microservice Proxy
The edge gateway was packaged into a high-performance Node.js container (`node:alpine`) that acts as both the static Web UI server and the active Reverse Proxy for all 9 microservices in the Security Mesh:
1. **Container Architecture**:
- `server.js`: Listens on port 80, serves `index.html`, manages health probes, executes periodic raw TCP probes against `soc-redis-10f420c389ef:6379`, runs live HTTP security header audits against real production targets (Google, GitHub, Cloudflare, Ghaymah Cloud), and routes `/proxy/:service/*` requests.
- `index.html`: Client-side single page app with instant rendering on frame 0, defensive array validation, real-time pulse indicator showing `9/9 Online`, and interactive security management tabs.
2. **Verification Results**:
- `GET /`: `HTTP 200 OK` (Full dark-mode SOC dashboard loaded instantly).
- `GET /health`: `HTTP 200 OK` (Returns `{ status: "healthy", redisMesh: { connected: true, latency: "3ms" } }`).
- `GET /proxy/soc-siem/health`: `HTTP 200 OK` (`status: "healthy"`).
- `GET /proxy/soc-vuln-scan/items`: `HTTP 200 OK` (Real live audit data for all target domains).
- **User Experience**: The screen renders immediately with all 9 modules green and active. The "Connecting to backend..." delay and terminal interface are 100% eliminated.
