Potential false positives
editBucket components may be deleted by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Bucket component deletions from unfamiliar users or hosts should be investigated. If a known behavior is causing false positives, it can be excluded from the rule.
Investigation guide
editThe AWS Filebeat module must be enabled to use this rule.
