IAM Policy

Identity and Access Management (IAM) Policy

Resource Type

AWS.IAM.Policy

Resource ID Format

For IAM Policies, the resource ID is the ARN.

arn:aws:iam::123456789012:policy/example-policy

Background

This resource represents an IAM Policy, which is an entity that, when attached to an identity or resource, defines their permissions. Entities that can have an IAM Policy attached are linked below:

AWS Managed Policies

Default in AWS are IAM Policies managed by AWS, which are distinct from a customer managed policy and inline policy. Generally, these policies are overly-permissive in nature and for that same reason, should generally be avoided. Panther will only store an AWS managed policy if it is attached to an IAM entity. Since IAM Policies exist within a globally-unique namespace, Panther preserves the stored ARN but modifies the Resource ID as follows:

// Original AWS Managed Policy ARN
arn:aws:iam::aws:policy/example-policy
‚Äč
// Stored Resource ID
arn:aws:iam::{ACCOUNT-ID}:policy/example-policy
