GitHub Repo - Apache module

What is CSRF Protector?

CSRF Protector Project has two parts:

Apache 2.x.x Module: An Apache Module which can be easily installed and configured in an Apache Server to protect it from CSRF vulnerabilities.

php library: A standalone php library which can be integrated with any existing web application or used while creating a new php project. All developer need to do is include the library and call the initiating function. View More

Its based on the research paper A Server- and Browser-Transparent CSRF Defense for Web 2.0 Applications - ACSAC 2011

Why CSRF Protector?

CSRF Protector is suitable for three group of developers:

Framework Developers can use the libraries and tools to strengthen their framework security
PHP Application Developers can use the library and tools to enhance their application security
New PHP Developers can use the tools and libraries to create secure applications from scratch

mod_csrfprotector - Apache 2.x.x Modules for mitigating CSRF attacks

What is mod_csrfprotector

Its an Apache 2.x.x Module (Currently 2.2.x) under development. It can be installed and configured in any Apache Server to protect it against Cross Site Request Forgery attacks. mod_csrfprotector provides protection to both POST and GET requests (not enabled by default).

How mod_csrfprotector works?

Once installed in Apache Server, every request that is made to the server, and validated against CSRF attacks by the input filters. Input filter follows a protocol as mentioned by developer in configuration, which helps the module to decide weather to validated the request. The input filter checks for appropriate token sent with request. Request if forwarded to other filters or content generator (like php or cgi) in validation is successful. Otherwise, appropriate actions are taken as per configuration. For ex: 403, Forbidden header is send to client. The Output filter, checks for content type of output generated by content generator and if it is `text/html` or `text/xhtml` it appends javascript code to the output. This js code in client side is responsible for attaching CSRFP_token with every required request sent from client.
