+Task5:
+
+Scenario
+	A ransomware attack has encrypted all files stored on Ghaymah Block Storage.
+	Users can no longer access their files, and the attacker demands payment in exchange 	for the 	decryption key.
+________________________________________
+1. Emergency Response Plan (First 60 Minutes)
+
+	0–15 Minutes: Identification & Isolation
+	Objectives
+•	Confirm that a ransomware attack has occurred. 
+•	Prevent the malware from spreading. 
+	Actions
+•	Disconnect affected virtual machines from the network. 
+•	Disable access to shared Block Storage volumes. 
+•	Block suspicious IP addresses using firewall rules. 
+•	Stop scheduled synchronization tasks. 
+•	Notify the security and incident response teams. 
+
+
+	15–30 Minutes: Investigation
+	Objectives
+	Determine the scope of the attack. 
+	Actions
+•	Review system and application logs. 
+•	Identify the ransomware entry point. 
+•	Determine which servers and storage volumes are affected. 
+•	Preserve logs and forensic evidence. 
+•	Check whether backups are intact. 
+
+	30–45 Minutes: Containment & Eradication
+	Objectives
+	Remove the ransomware and stop further encryption. 
+	Actions
+•	Isolate infected systems. 
+•	Scan all virtual machines with antivirus/EDR tools. 
+•	Remove malicious processes and scheduled tasks. 
+•	Rotate compromised credentials. 
+•	Patch exploited vulnerabilities. 
+
+	45–60 Minutes: Recovery Preparation
+	Objectives
+	Prepare for service restoration. 
+	Actions
+•	Verify the integrity of backups. 
+•	Restore critical services in a test environment.  
+•	Validate restored data.  
+•	Monitor systems for reinfection. 
+Gradually return services to production. 
+Timeline Summary
+Time	Activity
+0–15 min	Detect attack and isolate affected systems
+15–30 min	Investigate logs and identify affected resources
+30–45 min	Remove ransomware and secure infrastructure
+45–60 min	Restore from backups and validate services
+________________________________________
+
+2. Ghaymah Backup & Recovery Strategy
+
+Recovery Point Objective (RPO)
+	Definition: The maximum acceptable amount of data loss.
+	Proposed Value: 15 minutes
+	This means backups or snapshots should occur at least every 15 minutes for critical data.
+________________________________________
+Recovery Time Objective (RTO)
+	Definition: The maximum acceptable downtime before services are restored.
+	Proposed Value: 1 hour
+	Critical applications should be operational again within one hour.
+________________________________________
+Backup Strategy
+	Daily Incremental Backups
+	Capture only changes made since the previous backup.
+	Advantages:  Faster , Less storage usage 
+________________________________________
+Weekly Full Backup
+	Create a complete copy of all Block Storage volumes.
+	Advantages:  Faster restoration, Simplified disaster recovery 
+________________________________________
+Monthly Offline Backup
+	Store a copy outside the production environment.
+	Purpose: Protection against ransomware encrypting online backups. 
+________________________________________
+3-2-1 Backup Rule
+The organization should follow the 3-2-1 backup strategy:
+•	3 copies of the data (one primary + two backups). 
+•	2 different storage media (e.g., Block Storage and external storage/object storage). 
+•	1 off-site or offline backup stored separately from the production environment. 
+________________________________________
+3. Comprehensive Prevention Plan
+Identity & Access Management (IAM)
+•	Enable Multi-Factor Authentication (MFA). 
+•	Apply the Principle of Least Privilege. 
+•	Review user permissions regularly. 
+•	Rotate passwords and API keys. 
+________________________________________
+Network Security
+•	Enable firewalls. 
+•	Segment production and backup networks. 
+•	Restrict remote administration access. 
+•	Use VPN for administrative access. 
+________________________________________
+Endpoint Security
+•	Deploy Endpoint Detection and Response (EDR). 
+•	Keep operating systems and software patched. 
+•	Disable unnecessary services. 
+•	Enable application allow-listing where appropriate. 
+________________________________________
+Backup Protection
+•	Use immutable backups where possible. 
+•	Encrypt backup data. 
+•	Test backup restoration regularly. 
+•	Store backups in separate locations. 
+________________________________________
+
+Container Security
+•	Scan container images using Trivy before deployment. 
+•	Avoid running containers as root. 
+•	Store secrets securely. 
+•	Continuously monitor container activity. 
+________________________________________
+Monitoring & Detection
+•	Deploy a SIEM solution to centralize logs. 
+•	Configure alerts for: 
+o	Multiple failed logins. 
+o	Unusual file modifications. 
+o	Mass file encryption. 
+o	Privilege escalation attempts. 
+________________________________________
+Security Awareness
+•	Train employees to recognize phishing emails. 
+•	Conduct regular security awareness sessions. 
+•	Simulate phishing campaigns. 
+•	Define clear incident reporting procedures. 
+________________________________________
+Conclusion
+A successful ransomware response depends on rapid detection, immediate isolation, reliable backups, and tested recovery procedures. 
+By implementing layered security controls—including strong IAM, network segmentation, continuous monitoring, secure container practices, and a resilient backup strategy based on the 3-2-1 rule—organizations using Ghaymah Cloud can significantly reduce the impact of ransomware attacks and recover services efficiently.
