Sécurité web

Protégez vos utilisateurs des attaques les plus courantes.

Most attacks on websites are not clever. They abuse the same few mistakes, again and again, with automated tools. This track teaches you to look at your own app the way an attacker does, and then to close each door: SQL injection, cross-site scripting, weak password storage, stolen sessions, cross-site request forgery, leaked secrets, missing HTTPS and broken access control.

Every attack is shown in small, real code in JavaScript, Go, SQL and raw HTTP, next to the fix you can use today.
