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


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.


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.
