This detection rule is designed to capture events where files that are not permitted by Windows Code Integrity settings for protected processes are blocked. Each time an unauthorized file attempt is detected and subsequently blocked, an event with Event ID 3104 is generated. This is crucial for maintaining the security of protected processes by preventing the execution of potentially malicious or untrusted code. The rule helps in identifying privilege escalation attempts where attackers could try to execute disallowed files that might compromise sensitive system processes. Awareness of such events can enable quick response measures to mitigate potential security breaches.
