FGFW-ND-000115 - The FortiGate device must generate an immediate real-time alert of all audit failure events requiring real-time alerts.

Information

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected.

Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Log in to the FortiGate GUI with Super-Admin privilege.

1. Click Security Fabric.
2. Click Automation.
3. Click +Create New (Automation Stitch).
4. Assign a meaningful name.
5. For Trigger, select FortiOS Event Log.
6. For Event field, Click + (and choose a specific event type).
7. For Action, select Email, specify recipients, and Email subject.
8. Click OK.
