Summary
The rule 'Crowdstrike IP Allowlist Changed' monitors any changes made to the allowlist within the Crowdstrike Falcon console. The detection focuses on events where IPs are either added or removed from the allowlist, which can indicate potential actions taken by malicious actors, such as granting unauthorized access or blocking legitimate users. This rule responds to specific audit events, specifically focusing on different scenarios such as creating a new allowlist group, adding multiple IPs, and modifying existing entries. The rule is particularly concerned with operations related to the 'CreateAllowlistGroup' and 'UpdateAllowlistGroup' to catch any unauthorized alterations of the allowlist that could signal a compromise. Understanding these changes is crucial for maintaining security protocols and providing necessary validations around these actions. Thus, the expected results emphasize whether the logs align with legitimate administrative operations or raise red flags warranting further investigation.
