# CWE-778 Comprehensive Audit Logging Implementation
|
|
|
|
## Overview
|
|
|
|
This document describes the comprehensive audit logging implementation that addresses **CWE-778: Insufficient Logging** vulnerabilities. The implementation ensures all security-relevant events are logged with sufficient context for incident response, forensics, and compliance auditing.
|
|
|
|
**Implementation Date:** December 2024
|
|
**Compliance Standard:** CWE-778
|
|
**Status:** ✅ Complete
|
|
|
|
---
|
|
|
|
## What is CWE-778?
|
|
|
|
**CWE-778: Insufficient Logging** occurs when a system does not record security-relevant events, or records them without sufficient detail. This makes it difficult to:
|
|
- Detect security breaches
|
|
- Perform forensic analysis
|
|
- Track privilege escalation
|
|
- Identify compromised accounts
|
|
- Meet compliance requirements
|
|
|

|
## Implementation Summary
|
|
|
|
### New Logging Methods Added to SecurityAuditLogger
|
|
|
|
We enhanced the `SecurityAuditLogger` class in `backend/utils/securityAudit.js` with 8 new comprehensive logging methods:
|
|
|
|

## Database Schema
|
|
|
|
The audit logs are stored in the `security_audit_log` table:
|
|
|
|
```sql
|
|
CREATE TABLE IF NOT EXISTS security_audit_log (
|
|
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
|
user_id INTEGER,
|
|
action TEXT NOT NULL, -- Event type (token_issued, privilege_change, etc.)
|
|
result TEXT NOT NULL, -- success, failed, pending
|
|
details TEXT, -- JSON metadata
|
|
ip_address TEXT,
|
|
user_agent TEXT,
|
|
created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
|
|
FOREIGN KEY (user_id) REFERENCES users(id)
|
|
);
|
|
```
|
|
|
|
**Index:** `idx_security_audit_action_result_created` for fast filtering

## Usage Examples
|
|
|
|
### Query Token Issuance Events
|
|
|
|
```javascript
|
|
// Get all token issuance events for user 123 in last 7 days
|
|
const stats = await SecurityAuditLogger.getAuditStatistics(7);
|
|
console.log(stats.eventsByType.token_issued);
|
|
```
|
|
|
|
### Query Privilege Changes
|
|
|
|
```sql
|
|
SELECT * FROM security_audit_log
|
|
WHERE action = 'privilege_change'
|
|
AND created_at > datetime('now', '-30 days')
|
|
ORDER BY created_at DESC;
|
|
```
|
|
|
|
### Analyze Failed Logins by Device
|
|
|
|
```javascript
|
|
const deviceInfo = SecurityAuditLogger.extractDeviceInfo(req.headers['user-agent']);
|
|
console.log(`Login attempt from ${deviceInfo.deviceType} using ${deviceInfo.browser}`);
|
|
```
|
|
|
|
---
|
|
|
|
## Performance Considerations
|
|
|
|
### Logging Overhead
|
|
- **Async Operations:** All logging is non-blocking
|
|
- **Database Impact:** Minimal (single INSERT per event)
|
|
- **Index Usage:** Optimized with compound index
|
|
|
|
### Storage Requirements
|
|
- **Average Event Size:** ~500 bytes (JSON metadata)
|
|
- **Expected Growth:** ~10,000 events/month (high activity)
|
|
- **Storage Impact:** ~5 MB/month
|
|
|
|
### Retention Policy
|
|
- **Recommendation:** Keep audit logs for 90 days minimum
|
|
- **Archival:** Export to external system after 90 days
|
|
- **Cleanup Query:**
|
|
```sql
|
|
DELETE FROM security_audit_log
|
|
WHERE created_at < datetime('now', '-90 days');
|
|
```
|
|
|

|
|
|
|
## Future Enhancements
|
|
|
|
### Planned Features
|
|
- [ ] Real-time alerting for suspicious patterns
|

|
|
- [ ] Export to SIEM systems (Splunk, ELK)
|
|
- [ ] Geolocation tracking from IP addresses
|
|
- [ ] Session correlation across devices
