Which of the following actions does 'Block and Hide Detection' policy perform?

The 'Block and Hide Detection' policy in CrowdStrike Falcon operates by actively preventing malicious activity from occurring while simultaneously hiding those actions from detection display. This means that when a threat is identified, the policy intervenes to block the malicious process or activity and ensure that it does not trigger alerts or show up in the detection logs.

This approach is particularly useful in scenarios where you want to mitigate threats without alerting an adversary to the presence of a security tool or without the event being visible in standard reporting. By hiding the detection, it helps maintain operational security and limits the information an attacker may have about the defensive measures in place.

While other options describe different functionalities—such as merely logging activity, only detecting without taking action, or blocking without saving logs—they do not accurately reflect the dual action of blocking and concealing that characterizes the 'Block and Hide Detection' policy. This policy aims to ensure a proactive security posture while minimizing the visibility of its measures to potential threats.
