Abstract

An intrusion detection system is a device or an application which monitor network, system activities for malicious activities, policy violations and also produces reports to a management station. This paper surveys proposed work on Intrusion Detection System and describe about comprehensive classification of various IDS approaches according to their employed detection technique. The main categories explored in this paper are anomaly detection, rule based intrusion detection and PCA based modular neural network. Thus the paper’s main aim is to include the most recent advancement in the area intrusion detection system as well as predict the future course of research.

Abstract

Mobile ad hoc networks have inherently different properties than traditional wired networks. These new characteristics present different security vulnerabilities and this paper provides a detailed classification of these threats. Threats exist to a mobile ad hoc network both from external nodes unauthorised to participate in the mobile ad hoc networks, and from internal nodes, which have the authorisation credentials to participate in the mobile ad hoc network. Internal nodes giving rise to threats can be further divided according to their behaviour — failed, badly failed, selfish and malicious nodes. Failed and selfish nodes are those which do not perform certain operations that the protocol spec- ifies that they should, the former due to some unfore seen failure and the latter due to selfishness to conserve power. Badly failed nodes may perform operations incorrectly, introducing false and misleading information into the network. Malicious nodes may deliberately disrupt the network using a variety of attacks. All categories of node behaviour should be considered when designing protocols for mobile ad hoc networks.
