Goal-4-Task-4 Work Log - Audit Logging Framework

Task Summary

Implement enhanced audit logging framework in security/memory/audit.py meeting requirements from specs/memory-interface.md

Initial Assessment

• Current implementation covers core requirements:
  • Timestamped operations
  • Hashed keys (SHA-256)
  • RBAC integration
• Missing features:
  • Thread safety
  • Filtering capabilities
  • Integration tests

Implementation Plan

1. Add thread safety using threading.Lock
2. Implement filtering methods:
   • by_operation()
   • by_user()
   • by_time_range()
3. Create integration tests in tests/memory/test_audit.py
4. Verify RBAC integration

Work Commenced

2025-05-02T20:31:00Z - Starting implementation

[2025-05-02 20:33:00] Audit Logging Implementation Complete

Thread Safety:

• Added threading.Lock to protect critical sections
• All operations (logging, filtering, verification) are now thread-safe
• Tested with 10 threads making 100 log entries each (1000 total)

Filtering Methods Implemented:

1. by_operation(): Filters by operation type (create/read/update/delete)
2. by_user(): Filters entries by username
3. by_time_range(): Filters entries between timestamps (ISO format)

Test Coverage:

• Created comprehensive test suite in tests/memory/test_audit.py
• Tests cover:
  • Basic logging functionality
  • Thread safety under load
  • All filtering methods
  • Integrity verification
  • RBAC integration (via mock)

Security Considerations:

• All sensitive keys are hashed with SHA-256
• Timestamps use UTC to avoid timezone issues
• Integrity verification protects against tampering

Deliverables Completed:

1. audit.py implementation in security/memory/
2. Integration tests in tests/memory/test_audit.py

Next Steps:

• Await integration testing by QA team
• Prepare for deployment in next sprint
