The rule 'AWS.CloudTrail.EventSelectorsDisabled' identifies when a CloudTrail Trail has been modified to disable management events for one or more resource types. The modification could potentially hinder the visibility into critical account activities, creating possible security blind spots which attackers could exploit. The rule triggers based on logging operations that modify event selectors via the AWS CloudTrail service. A critical aspect to monitor is whether an event source is excluding management events, leading to potential evasion of security tracking mechanisms. This rule uses outputs from the CloudTrail logs specifically looking for the 'PutEventSelectors' event to determine if permission events are incorrectly configured. If management events are included in event selectors, responses and logs are expected to show the event as not disabled. Conversely, if no management events are logged it indicates that the event selectors are incorrectly configured, leading to rule triggers.
