Accepted Answer

Change the exploit protection behavior for the specific technique to 'Report' instead of 'Terminate'.. Putting the exploit protection module into Report (Audit) mode allows verification of potential blocks without disrupting user productivity.

Answer

Add the browser executable path to the OS exclusions list in Cortex XDR.

Answer

Disable memory protection features globally in the agent settings profile.

Answer

Enable Agent Self-Protection to prevent local interference.

Question 10

An administrator is preparing to deploy Cortex XDR agents to 500 remote endpoints using a software deployment tool. Where can the administrator download the latest installation packages and transforms?

Answer

Run 'pan-xdr-cli check' in the system console.

Question 12

An enterprise security team discovers that a custom line-of-business application is triggering a Behavioral Threat Protection (BTP) alert in Cortex XDR. The behavior involves unusual process injection techniques that are legitimate for this application. How can the administrator suppress this specific alert without disabling BTP for other applications?

Accepted Answer

Create a Behavioral Threat Protection exception specifying the application hash and the triggered rule ID.. Creating an exception based on the BIOC rule ID or signature hash prevents specific false positives while keeping behavioral monitoring active.

Answer

Lower the threat severity threshold for Behavioral Threat Protection in the agent profile.
