Here is a 150 word summary of the blog post:

The blog post discusses using AWS CloudTrail to audit Amazon Verified Permissions policies and authorization decisions. CloudTrail logs management events for Verified Permissions API calls like CreatePolicy and DeletePolicy. To demonstrate, the author shows CloudTrail entries for PutSchema calls. Verified Permissions data events like IsAuthorized are not logged by default. To enable this, the author creates a new CloudTrail trail specifically for Verified Permissions data events. After making some test API calls, CloudTrail log entries appear showing the authorization decisions. The key difference is that data events have managementEvent set to false and eventCategory set to data. Overall, integrating Verified Permissions with CloudTrail increases observability into policy and access control activity, aiding security and compliance auditing by revealing which users accessed what resources.
