Description

Identifies the modification of an AWS RDS DB instance or cluster to disable the deletionProtection feature. Deletion protection prevents accidental or unauthorized deletion of RDS resources. Adversaries with sufficient permissions may disable this protection as a precursor to destructive actions, including the deletion of databases containing sensitive or business-critical data. This rule alerts when deletionProtection is explicitly set to false on an RDS DB instance or cluster.

Detection logic

any where event.dataset == "aws.cloudtrail"
    and event.provider == "rds.amazonaws.com"
    and event.action in ("ModifyDBInstance", "ModifyDBCluster")
    and event.outcome == "success"
    and stringContains(aws.cloudtrail.request_parameters, "deletionProtection=false")
