Deprecated - AWS RDS Security Group Deletion

Last updated a month ago on 2025-11-21

About

Identifies the deletion of an Amazon Relational Database Service (RDS) Security group. Modern RDS deployments run in a VPC and use standard EC2 security groups instead. This rule should be retained only for historical log analysis on legacy CloudTrail data. We recommend relying on "AWS EC2 Security Group Configuration Change" rule for network-control changes impacting RDS in VPC-based deployments.

False Positive Examples
An RDS security group deletion may be done by a system or network administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. Security group deletions by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
