§Permission Manager (IPC Security)

§RESPONSIBILITIES

This module provides role-based access control (RBAC) for IPC operations. It validates permissions for all incoming IPC messages and logs security events for comprehensive audit trails.

§ARCHITECTURAL ROLE

This module is the security enforcement layer in the IPC architecture, ensuring that all operations are authorized based on user roles and permissions.

§KEY COMPONENTS

  • PermissionManager: Main permission validation and management structure
  • SecurityContext: Context information for permission validation
  • SecurityEvent: Audit log entry for security events
  • SecurityEventType: Types of security events

§ERROR HANDLING

Permission validation returns Result types with descriptive error messages when access is denied.

§LOGGING

All security events are logged to the audit log. Info-level logging for access grants, error-level for permission denials.

§PERFORMANCE CONSIDERATIONS

  • Permission definitions cached in RwLock for fast concurrent access
  • Role resolution optimized with HashMap lookups (O(1) complexity)
  • Audit log limited to last 1000 events to prevent memory bloat

§TODO

  • Add permission caching with TTL
  • Implement permission inheritance
  • Add permission alias support
  • Implement group-based permissions
