  3. Insecure protocol: The use of the file protocol in the subject line is insecure, as it allows access to local files without proper authentication or authorization.

The Anatomy of the URL

It was a typical Monday morning at AWSecure, a top-secret research facility nestled in the heart of the Pacific Northwest. Dr. Rachel Kim, a renowned cybersecurity expert, sipped her coffee while staring at her computer screen. She was about to start her day by checking the callback URLs for the company's latest project, codenamed "Eclipse." callback-url-file-3A-2F-2F-2Fhome-2F-2A-2F.aws-2Fcredentials

Use IAM Roles for EC2: Assign permissions directly to the instance. The application will fetch temporary, rotating credentials from the Instance Metadata Service (IMDS) rather than a static file on disk. 3. Enforce IMDSv2
