The Slack IDP Configuration Changed rule is designed to detect alterations to the Identity Provider (IdP) configuration in Slack organizations. This is significant because changes to IdP settings can affect authentication processes, potentially leading to unauthorized access or compromised user credentials. The rule monitors Slack audit log events that indicate when IdP configurations are added, deleted, or updated by users. It also ignores the 'user_logout' action, as it is not relevant to the detection of configuration changes. The rule is enabled with a high severity rating due to the critical nature of identity management in securing organizational data. The detection logic inspects audit log entries for specific actions related to IdP configurations, ensuring timely alerts for any changes that could indicate security vulnerabilities.
