As running different business websites, I wanted to secure them by using an intrusion detection.
The tool I decided to use is
PHPIDS. For all who wants to know more about it, there is an article available at
Heise Security.
The Zip file does not include PHPIDS, which is available at
www.php-ids.org/downloads/. But it does include a MODx plugin, ready to use.
PHPIDS is LGPL licensed, my plugin too.
You can download it from
