feat: Add comprehensive security enhancements
Security Enhancements
Overview
This PR implements comprehensive security improvements across the codebase, focusing on authentication, authorization, audit logging, and secure data handling.
Changes
1. Role-Based Access Control (RBAC)
- Implemented granular permission system with predefined roles (Admin, User, Viewer, Operator)
- Added role assignment tracking with metadata (assignment time, assigner, last access)
- Implemented rate limiting and automatic lockout after failed attempts
- Added role usage monitoring and audit trail
2. Audit Logging System
- Created secure audit logging with JSON formatting
- Implemented log rotation based on size and age
- Added comprehensive event tracking including:
- User actions
- Resource access
- Authentication attempts
- System events
- Included IP address and user agent tracking
3. Secrets Management
- Implemented secure secrets storage with AES-GCM encryption
- Added in-memory caching with mutex protection
- Implemented secure file-based persistence
- Added encryption key validation and management
4. TLS Configuration
- Enhanced TLS configuration with secure defaults
- Added certificate validation and verification
- Implemented secure cipher suite selection
- Added certificate file permission checks
5. API Security
- Added rate limiting per IP and globally
- Implemented comprehensive security headers
- Added input validation and sanitization
- Enhanced error handling and logging
Security Impact
These changes significantly improve the security posture of the application by:
- Preventing unauthorized access through RBAC
- Detecting and preventing brute force attacks
- Ensuring secure communication through TLS
- Providing audit trail for security events
- Protecting sensitive data through encryption
Testing
- Added unit tests for RBAC functionality
- Implemented integration tests for audit logging
- Added security headers validation
- Tested rate limiting functionality
Dependencies
No new external dependencies were added.
Breaking Changes
