Web servers will often return an error message when a user tries to access a broken link. Broken links are also often known as “dead links” or “link rots.” Examples of a broken link error code

For longer lived JWTs it's highly recommended toįollow the OAuth standards to revoke access.ĭevelopers and QA staff should include functional access control unitĪnd integration tests. Opportunity for an attacker is minimized. Stateless JWT tokens should rather be short-lived so that the window of Stateful session identifiers should be invalidated on the server after logout. Rate limit API and controller access to minimize the harm from Log access control failures, alert admins when appropriate (e.g., git) and backup files are not present within web roots. Unique application business limit requirements should be enforced byĭisable web server directory listing and ensure file metadata (e.g., Model access controls should enforce record ownership rather thanĪccepting that the user can create, read, update, or delete any The application, including minimizing Cross-Origin Resource Sharing (CORS) usage.
