mod_anti_tamper – Anti Tamper Module for Apache 2.x

What Is Mod AntiTamper (AT)

AntiTamper is an Apache 2.x module that could be used to prevent some sort of url and cookie tampering.

Specifically, AT could stop a lot of those malicious bots that take advantage from search engines. Moreover, attack techniques like HTTP Response Splitting and session hijacking/fixation will be mitigated.

Is important to notice that mod_anti_tamper is not an alternative to mod_security, which is more exaustive and useful for all web situations. AT could be a complement to mod_security.

Introduction
- What is HMAC
HMAC is a validation algorithm to check the integrity of informations coupled with a secret password (more here).
AT will automatically generate a password and will save it in a ‘safe’ place (root owner with 600 mode).

How AT Works
AT is composed by two primary active components.
1. A filter for url links integrity check.
2. A filter for cookie integrity check.
