Paparan berkas for Express

critical5 checks

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

What Express 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

Express context
