Implementing a Logging Function involves setting up and managing systems to record events and activities in an IT environment for auditing, security monitoring, and compliance purposes.

Key Considerations for Implementing a Logging Function:
1.) What to Log
- Identify critical events that need to be recorded, such as:
- User Activities: Login attempts (successful and failed), file access, and administrative actions.
- System Events: Software updates, configuration changes, and security policy modifications.
- Security Incidents: Unauthorized access attempts, malware detections, and firewall rule changes.
- Example: Logging all failed login attempts to detect brute-force attacks.
2.) Where to Store Logs
- Logs should be stored securely to prevent unauthorized access, tampering, or loss.
- Options include:
- Centralized Log Management Systems: SIEM tools like Splunk, Graylog, or ELK Stack for centralized log collection.
- Cloud-Based Storage: Secure cloud logging services like AWS CloudTrail or Azure Monitor Logs.
- On-Premises Secure Storage: Dedicated log servers with restricted access and encryption.
- Example: Configuring a database audit log to store all queries and changes in a secure, encrypted storage location.
3.) How Long to Retain Logs
- Log retention policies should align with regulatory requirements, business needs, and security best practices.
- Compliance regulations require different retention periods:
- PCI DSS: 1 year
- HIPAA: 6 years
- SOX: 7 years
- Example: A financial institution retains transaction logs for 7 years to comply with legal and regulatory requirements.
