Detecting anomalous network traffic in organizational private networks

Abstract

During the last decade, network monitoring and intrusion detection have become essential techniques of cyber security. Nowadays, many institutions are using advanced solutions for detecting malicious network traffic, discovering network anomalies, and preventing cyber attacks. However, most research in this area has not been conducted specifically for organizational private networks, and their special properties have not been considered. In this paper, we first present a study of traffic patterns in a corporate private network, and then propose two novel algorithms for detecting anomalous network traffic and node behavior in such networks.
