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 user’s session. PHPIDS enables you to see who’s attacking your site and how and all without the tedious trawling of logfiles or searching hacker forums for your domain. Last but not least it’s licensed under the fair LGPL! Contributions ------------- [](#contributions) If you would like to contribute, please open a pull request.

Credits ------- [](#credits) The project was started by Christian Matthies and Mario Heiderich . Mario spend a lot of time maintaining PHPIDS mostly on his own. Huge props for that.
