Session Management +- **Model:** `models/session.rs` - Complete session repository with MongoDB +- **Manager:** `security/session_manager.rs` - High-level session management API +- **Handlers:** `handlers/sessions.rs` - REST API endpoints for session management +- **Features:** + - Create sessions with device tracking + - List all active sessions for a user + - Revoke specific sessions + - Revoke all sessions (logout from all devices) + - Automatic cleanup of expired sessions + +### 2. Audit Logging +- **Model:** `models/audit_log.rs` - Audit log repository +- **Logger:** `security/audit_logger.rs` - Audit logging service +- **Event Types:** + - Login success/failure + - Logout + - Password recovery/change + - Account creation/deletion + - Data access/modification/sharing + - Session creation/revocation +- **Features:** + - Log all security-relevant events + - Query logs by user + - Query recent system-wide events + +### 3. Account Lockout +- **Service:** `security/account_lockout.rs` - Brute-force protection +- **Features:** + - Track failed login attempts per email + - Progressive lockout durations + - Configurable max attempts and duration + - Automatic reset on successful login + - Default: 5 attempts, 15min base, 24hr max + +### 4.
