: Use threat feeds to automatically escalate changes that match known malicious hashes or attack techniques.
Implementing a robust FIM strategy requires moving beyond simple compliance to active security. The Top Ten of File-Integrity Monitoring
: Capture baselines immediately after a clean installation or security hardening, aligned with industry standards like CIS Benchmarks or DISA STIGs . : Use threat feeds to automatically escalate changes
: Integrate FIM logs with Security Information and Event Management (SIEM) for broader context, such as matching a file change with a failed login attempt. : Integrate FIM logs with Security Information and
File Integrity Monitoring (FIM) is a security process that validates the integrity of operating systems and application software files.
