smss.exe process triggering false positive on TMS

L3 Networker

Dear community!


We are getting a lot of security events on our TMS because the Behavioral Threat module analysis is triggering false positives when inspecting smss.exe process.

"smss.exe" is a file that manages the startup of all user sessions in Windows.



+ Does anyone else has this issue?

+ In order to avoid those events, is the only solution to create a behavioral threat rule exception for process smss.exe?


The agent version is 6.1.5


Thank you!

Hi there-


BTP should not be triggering on the smss process alone.  BTP is looking at sequences of events and based on the behavior of the entire sequence, it can trigger an alert.  After reviewing the Analysis tab in TMS that shows all of the events that triggered the alert, if you determine that this is s FP, you should indeed create exclusion for this scenario.
