Intrusion Detection For PHP Applications With PHPIDS

Post date: June 24, 2008, 14:06 Category: Security Views: 5228 Comments
Tutorial quote: This tutorial explains how to set up PHPIDS on a web server with Apache2 and PHP5. PHPIDS (PHP-Intrusion Detection System) is a simple to use, well structured, fast and state-of-the-art security layer for your PHP based web application. The IDS neither strips, sanitizes nor filters any malicious input, it simply recognizes when an attacker tries to break your site and reacts in exactly the way you want it to. Based on a set of approved and heavily tested filter rules any attack is given a numerical impact rating which makes it easy to decide what kind of action should follow the hacking attempt. This could range from simple logging to sending out an emergency mail to the development team, displaying a warning message for the attacker or even ending the userís session.
