Intrusion Detection Systems: Study and Comparison

Abstract

With the huge rise of the internet and the notable technological development in recent years, the number of users has greatly increased. The internet serves countless personal and professional needs for people and companies. However, this interconnection of computers also allows attackers and malicious users to exploit these resources for malicious purposes, which exposes today’s computer networks to an increasing number of attacks and threats security, with new types of techniques and attacks appearing continuously and which are increasing both in number, severity and impact. For these reasons, researchers and systems administrators seek effective and automated security strategies and solutions in order to reduce damage or stop a big part of threats able to protect the corporate network and information systems. One of the best solution in this context are Intrusion Detection Systems (IDS), which are used for protecting computer networks and information systems.
