Recently, there has been shift to multi-core processors and consequently multithreaded application design. Multithreaded Network Intrusion Detection and Prevention Systems (NIDPS) are now being considered. Suricata is a multithreaded open source NIDPS, being developed via the Open Information Security Forum (OISF). It is increasing in popularity, as it free to use under the General Public Licence (GPL), with open source code. This paper describes an experiment, comprising of a series of innovative tests to establish whether Suricata shows an increase in accuracy and system performance over the de facto standard, single threaded NIDPS Snort.
