  • User Actions - Who did what, when, and from where
  • Resource Changes - Before/after snapshots of modifications
  • Permission Changes - Role and permission assignments
  • System Events - Backups, restores, deployments
  • Security Events - Authentication, authorization denials
  • API Access - All API calls and their results

Best Practices​

1. Regular Audit Review​

  • Weekly: Check for failed access attempts
  • Monthly: Review permission changes
  • Quarterly: Generate compliance reports
  • Annually: Perform full security audit

2. Alert on Critical Events​

Set up notifications for:

  • User deletion
  • Permission elevation
  • Failed authentication attempts (>5 in 5 minutes)
  • System configuration changes
  • Network deletion

3. Separate Audit Admin Role​

Create a dedicated audit administrator role with:

  • Full audit log READ access
  • Report generation permission
  • No other operational permissions

4. Export and Archive​

  • Export logs regularly for long-term storage
  • Archive to write-once storage for legal holds
  • Maintain offline backups for disaster recovery
  • Use cryptographic verification

5. Monitor for Anomalies​

  • Alert if user performs unusual actions
  • Flag bulk deletions
  • Detect unusual access times
  • Monitor failed login attempts

Troubleshooting​

Missing Audit Logs​

  1. Check retention settings - Verify logs haven't been purged
  2. Check user permissions - Verify user has audit log access
  3. Check date range - Verify querying correct time period
  4. Check API key permissions - Ensure key includes SYSTEM_MONITOR

Audit Log Export Fails​

  1. Check disk space - Ensure sufficient storage for export
  2. Check network connectivity - If exporting to S3/GCS
  3. Check credentials - Verify cloud storage credentials
  4. Check file permissions - Ensure write permissions to export directory

Report Generation Slow​

  1. Reduce date range - Query shorter time periods
  2. Filter results - Use specific action or resource type
  3. Archive old logs - Move logs older than 6 months to archive
  4. Check system load - Audit query may be resource intensive
