IDS – Creating a simple Intrusion Detection System using Apache mod_rewrite
Using the Apache mod_rewrite module and a bit of php code I have devised a basic Intrusion Detection System for Apache running on Linux / Unix operating systems.
This is primarily as a demonstration of how aspects of an IDS can be implemented using existing tools provided in Linux and it’s applications. It could however be used with other reporting tools, or to feed the information into a full IDS to provide reporting or real time alerting.
