||||
ORDER BY created_at DESC;
|
||||
```
|
||||
|
||||
### 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;
|
||||
```
|
||||
|
||||
### Get Audit Statistics
|
||||
```javascript
|
||||
const stats = await SecurityAuditLogger.getAuditStatistics(30);
|
||||
console.log(stats.eventsByType);
|
||||
console.log(stats.privilegeChanges);
|
||||
```
