Pi-IDS: evaluation of open-source intrusion detection systems on Raspberry Pi 2

Intrusion detection and prevention systems (IDS/IPS) are a critical component of computer network security. This paper presents the results of an experiment comparing two open source IDS - Snort IDS and Bro IDS on a multi-purpose and low-cost computer called Raspberry Pi 2 (Model B), with a specific objective of determining their performance, efficiency and efficacy for use in computer network environments, where cost is a determining factor. Such environments could include SOHO and educational institution computer networks.
