Comprehensive Security Module Tests - ADDER+ Protocol Compliance
=================================================================
CRITICAL: Security modules require 100% coverage per ADDER+ completion criteria.
This module provides comprehensive testing for all security components including
access control, threat detection, input validation, and compliance monitoring.
Test Strategy: Property-based testing + functional validation + security boundary verification
Architecture: Defensive programming + type safety + contract validation
Coverage Target: 100% for all security-critical components
