Study of intrusion detection systems

Abstract

This paper presents the methodologies of IDS technologies. Essentially, any system requiring security must be protected from attacks. Intrusion detection systems are used to detect unusual activity in a network of computer systems to identify if activity is unfriendly or unauthorized in order to enable a response to that violation. To achieve this, there are two main types of IDS: network-based and host-based. This paper outlines these two types of IDS respectively and highlights the advantages of each kind. © 2013 Trade Science Inc. - INDIA.
