Opened: Nov 27, 2018

Severity: 3-Major

Symptoms

The DoS visibility screens (Monitoring :: Security :: Reporting : DoS) may display DNS and Network protocol DoS attacks with the incorrect mitigation details.

Impact

Network or DNS DoS attacks, detected by a DoS profile with detect-only or learn-only protection, display mitigation as Blocking instead of the configured Transparent protection. This does not affect the reported traffic data found in the DoS visibility dimensions and charts.

Conditions

An attacked object assigned to a DoS profile with either DNS or Network security protocols that are configured to have detect-only or learn-only states for DoS attacks.

Workaround

None.

Fix Information

None
