The 'Failed Code Integrity Checks' rule is designed to monitor and identify code integrity failures within Windows environments. The detection mechanism relies on Event IDs 5038 and 6281, which indicate potential alterations to code integrity such as missing page hashes or corrupted drivers. These anomalies often suggest unauthorized modifications to binaries, thereby posing a risk to system security. In practice, the rule is crucial for detecting instances of tampering that could compromise system integrity and reliability, as it allows security teams to respond to suspected infiltration attempts or malware infections that attempt to circumvent security protocols by altering legitimate system components.
