[All PCDRA Questions]

Which of the following protection modules is checked first in the Cortex XDR Windows agent malware protection flow?

Show Suggested Answer Hide Answer
Suggested Answer: A

The first protection module that is checked in the Cortex XDR Windows agent malware protection flow is the Hash Verdict Determination. This module compares the hash of the executable file that is about to run on the endpoint with a list of known malicious hashes stored in the Cortex XDR cloud. If the hash matches a malicious hash, the agent blocks the execution and generates an alert.If the hash does not match a malicious hash, the agent proceeds to the next protection module, which is the Restriction Policy1.

The Hash Verdict Determination module is the first line of defense against malware, as it can quickly and efficiently prevent known threats from running on the endpoint. However, this module cannot protect against unknown or zero-day threats, which have no known hash signature.Therefore, the Cortex XDR agent relies on other protection modules, such as Behavioral Threat Protection, Child Process Protection, and Exploit Protection, to detect and block malicious behaviors and exploits that may occur during the execution of the file1.

This is a great question to test our understanding of the Cortex XDR agent's security features. I'll carefully review the options and try to apply my knowledge of how the agent works to determine the correct answer.

I think you're both partially correct. The agent does check the hash first, but it also considers behavioral analysis before making a final decision.
