What does BYPASS_POLICY TTP mean? The Cb Defense User Guide does not provide sufficient information on the BYPASS_POLICY TTP.


  • BYPASS_POLICY TTP is set when we identify a driver callback that includes specially crafted command line arguments and an application attempted to bypass the device’s default security policy. See Cb Defense User Guide.
  • What this means is that BYPASS_POLICY TTP is added anytime the Sensor observes that something is trying to bypass the PowerShell execution policy. 

Additional Notes

  • There are several ways that you can bypass the PowerShell execution policy. You can execute “powershell –ExecutionPolicy Bypass” and it will start a PowerShell session that allows for running scripts and keeps the lowered permissions isolated to just the current running process. Nothing is blocked and there are no warnings or prompts.  
  • You can also execute “powershell –ExecutionPolicy Unrestricted” and it will start a powershell that Loads all configuration files and runs all scripts. If you run an unsigned script that was downloaded from the Internet, you are prompted for permission before it runs.
