Inside TYPO3

3.10. Security in TYPO3

3.10.1. Default security includes:

The security dealt with here regards the backend of TYPO3.

  1. Passwords for backend login are not sent clear-text (front-end user logins are!). They are md5-hashed together with a unique string sent from the server and thus hard to decipher. Editing the passwords in the backend interface also md5-hashes the password before it's sent to the server.
    This is not true encryption, it just makes it hard to find/guess the passwords.

  2. Sessions for backend and frontend users are done with a 32 byte cookie (md5-hash) which is looked up in the database and restores the session. A session lasts for little less than 2 hours with idle-time. Sessions might be locked to (parts of) the remote IP address of the user and the HTTP_USER_AGENT identification string to prevent session hi-jacking.
