Key Features Implemented

✅ Token Lifecycle Tracking

• All JWT token creation events logged (5 points)
• Token revocation logged (2 points: logout, password change)
• Metadata: tokenType, purpose, expiresIn, deviceInfo

✅ Privilege Change Tracking

• Role changes logged with full context (2 points)
• Metadata: previousRole, newRole, changedBy, targetUsername

✅ Account Status Tracking

• Activation/deactivation logged (1 point)
• Metadata: previousStatus, newStatus, changedBy, reason

✅ Device Fingerprinting

• User-agent parsing for device type, OS, browser
• Detection: mobile, tablet, desktop, bot
• OS: Windows, macOS, Linux, Android, iOS
• Browser: Chrome, Firefox, Safari, Edge, Opera

✅ Comprehensive Metadata

• Client ID (user ID)
• IP address
• Device information
• Timestamps (millisecond precision)
• Action context (who changed what for whom)

---

Security Compliance

CWE-778 Requirements Met

✅ Log all login attempts
✅ Log token issuance (OAuth, JWT, etc.)

Usage

Query Token Issuance Events

SELECT * FROM security_audit_log 
WHERE action = 'token_issued' 
  AND created_at > datetime('now', '-7 days')
ORDER BY created_at DESC;

Query Privilege Changes

SELECT * FROM security_audit_log 
WHERE action = 'privilege_change' 
  AND created_at > datetime('now', '-30 days')
ORDER BY created_at DESC;

Get Audit Statistics

const stats = await SecurityAuditLogger.getAuditStatistics(30);
console.log(stats.eventsByType);
console.log(stats.privilegeChanges);
