Goal-2-Task-4 Work Log

Task: Audit Logging Integration

Initial Assessment

• Need to implement comprehensive audit logging in RBACEngine
• Must meet SYM-SEC-004 requirements
• Current implementation lacks:
  • HMAC integrity protection
  • Complete field set
  • Thread-safe sequence numbering

Implementation Plan

1. Update _audit_access_attempt() to:
   • Include all required fields from specification
   • Add HMAC signature
   • Implement thread-safe sequence numbering
2. Add verify_audit_log_integrity() method
3. Write unit tests for new functionality

Changes Required

1. Add fields to audit log entries:
   • Timestamp (UTC)
   • Sequence number
   • Operation type
   • Role involved
   • Certificate fingerprint
   • Result (success/failure)
   • HMAC signature
2. Implement HMAC-SHA256 signing
3. Add thread-safe sequence counter
