Nowadays, computer systems have become more vulnerable to intrusions than ever. However, there is a limited number of open-source solutions to intrusion detection. Commercial products and hardware solutions are far too expensive for low-end users and enterprises. Our current research efforts focus on a fast, open-source intrusion detection system based on Snort and enriched with a fast pattern-matching algorithm, E2xB. i-Guard, the system we propose, is faster than existing solutions, even when it operates under attack conditions. Furthermore, it can be installed in every system, as it is a software-only solution, with a minimal cost of installation and maintenance.
