Paparan berkas for AWS Lambda

critical5 checks

Repositories, environment files, database dumps and backups are the fastest path from reconnaissance to full compromise.

What AWS Lambda must have

  • /.git and /.svn not reachable
  • /.env, /.env.local and config backups return 404
  • No .sql, .zip or .tar.gz dumps in the web root
  • Debug consoles and admin panels not publicly reachable
  • Directory listing disabled

How to fix it

  1. 1Serve nothing from the web root that is not meant to be public
  2. 2Block dotfiles at the edge and rotate every secret that was exposed

AWS Lambda context

Event-driven serverless functions on AWS.

Function URLs bypass API Gateway controls; scope IAM roles to the minimum.
