== Sensitive Code Example

This policy allows all users, including anonymous ones, to access an S3 bucket:

[source,python]
----
from aws_cdk.aws_iam import PolicyStatement, AnyPrincipal, Effect
from aws_cdk.aws_s3 import Bucket

bucket = Bucket(self, "ExampleBucket")
        
bucket.add_to_resource_policy(PolicyStatement(
  effect=Effect.ALLOW,
  actions=["s3:*"],
  resources=[bucket.arn_for_objects("*")],
  principals=[AnyPrincipal()] # Sensitive
))
----

== Compliant Solution

This policy allows only the authorized users:

[source,python]
----
from aws_cdk.aws_iam import PolicyStatement, AccountRootPrincipal, Effect
from aws_cdk.aws_s3 import Bucket

bucket = Bucket(self, "ExampleBucket")
        
bucket.add_to_resource_policy(PolicyStatement(
  effect=Effect.ALLOW,
  actions=["s3:*"],
  resources=[bucket.arn_for_objects("*")],
  principals=[AccountRootPrincipal()]
))
----
