A firewall application on SOHO networks with Raspberry Pi and snort

Abstract

In small and home office (SOHO) computer networks, an intrusion detection system can be activated to intercept the possible attack. Network traffic analysis is the basis of attack detection methods. In the intrusion detection process, both hardware and software solutions are available, as well as in systems that are bundled together. Hosting these systems in SOHO networks is usually negligible because it is considered a costly and laborious investment. In order to overcome this disadvantage open source code Intrusion Detection Systems (IDS) such as snort and strata can be used together with raspberry pi computers. In this study, a raspberry pi device was prepared on a small scale network and a network traffic analysis application was performed with the snort IDS module installed on it. It has been determined that some of the malicious traffic on the network by activated developing system.
