Question 46 - PCDRA discussion

To prevent the Cortex XDR Agent from blocking execution of a file based on the digital signer in Windows and macOS, one way to add an exception for the signer is to add the signer to the allow list in the malware profile. A malware profile is a profile that defines the settings and actions for malware prevention and detection on the endpoints. A malware profile allows you to specify a list of files, folders, or signers that you want to exclude from malware scanning and blocking.By adding the signer to the allow list in the malware profile, you can prevent the Cortex XDR Agent from blocking any file that is signed by that signer1.

Let's briefly discuss the other options to provide a comprehensive explanation:

A) In the Restrictions Profile, add the file name and path to the Executable Files allow list: This is not the correct answer. Adding the file name and path to the Executable Files allow list in the Restrictions Profile will not prevent the Cortex XDR Agent from blocking execution of a file based on the digital signer. A Restrictions Profile is a profile that defines the settings and actions for restricting the execution of files or processes on the endpoints. A Restrictions Profile allows you to specify a list of executable files that you want to allow or block based on the file name and path.However, this method does not take into account the digital signer of the file, and it may not be effective if the file name or path changes2.

B) Create a new rule exception and use the signer as the characteristic: This is not the correct answer. Creating a new rule exception and using the signer as the characteristic will not prevent the Cortex XDR Agent from blocking execution of a file based on the digital signer. A rule exception is an exception that you can create to modify the behavior of a specific prevention rule or BIOC rule. A rule exception allows you to specify the characteristics and the actions that you want to apply to the exception, such as file hash, process name, IP address, or domain name.However, this method does not support using the signer as a characteristic, and it may not be applicable to all prevention rules or BIOC rules3.

D) Add the signer to the allow list under the action center page: This is not the correct answer. Adding the signer to the allow list under the action center page will not prevent the Cortex XDR Agent from blocking execution of a file based on the digital signer. The action center page is a page that allows you to create and manage actions that you can perform on your endpoints, such as isolating, scanning, collecting files, or executing scripts.The action center page does not have an option to add a signer to the allow list, and it is not related to the malware prevention or detection functionality4.

In conclusion, to prevent the Cortex XDR Agent from blocking execution of a file based on the digital signer in Windows and macOS, one way to add an exception for the signer is to add the signer to the allow list in the malware profile. By using this method, you can exclude the files that are signed by the trusted signer from the malware scanning and blocking.
