CSRF Mitigation methods

Overview
CSRF is an attack which forces an end user to execute unwanted actions on a web application in which he/she is currently authenticated. With a little help of social engineering (like sending a link via email/chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. A successful CSRF exploit can compromise end user data and operation in case of normal user. If the targeted end user is the administrator account, this can compromise the entire web application.

OWASP CSRF Protector Project
OWASP CSRF Protector project comes in two parts :
 * Standalone php library:  This library can be both easily integrated with both existing web application or easily used while developing a new one.
 * Transparent Apache Module:  Can be installed on Apache 2.x.x servers to provide CSRF mitigation without doing any modification in web application logic or codes.
