The GitHub Org IP Allow List modified rule detects changes made to the IP allow list associated with a GitHub organization. This rule is part of GitHub audit logs, monitoring actions that potentially impact the security of the organization by allowing or disallowing specific IP addresses from accessing the organization's resources. Key attributes such as 'actor' and 'action' are evaluated to verify modifications to the allow list; for example, creating a new IP entry or disabling the existing allow list. By establishing this monitoring, organizations can ensure that all modifications to the IP access settings are legitimate and authorized, ultimately maintaining better security posture against misconfigurations or malicious activities. Further guidance for managing IP addresses for GitHub apps can be found in the documentation linked in the reference section.
