Detects the first time an AWS identity successfully deletes an IAM managed policy whose ARN contains guardrail-related keywords (for example Boundary, Deny, Restrict, Guard, SCP, Guardrail). Adversaries who have obtained elevated IAM privileges may delete policies to remove restrictive permissions boundaries, eliminate deny-based guardrails, or clean up after a privilege escalation operation. Infrastructure-as-code tools (Terraform, CloudFormation, Pulumi, and Ansible) are excluded because policy lifecycle management is a routine part of automated deployments. A policy deletion by an identity not seen performing this activity during the prior seven days may indicate newly compromised credentials being used to modify the account's permission structure.
