NIS08-1: A Multi-level Security Based Autonomic Parameter Selection Approach for an Effective and Early Detection of Internet Worms

Abstract

In light of the fast propagation of recent Internet worms, human intervention in securing the Internet during worm outbreaks is of little significance. In order to reduce the damage worms may cause, existing Intrusion Detection Systems (IDSs) need to be adaptive to the security-related requirements of their monitoring networks. This paper presents a Multilevel security based Autonomic Parameter Selector (MAPS) that can be implemented over any existing IDSs. The deployment architecture consists of a number of hierarchically placed local security managers, metropolitan security managers, and a global security manager. These security managers report events to a Worm Advisory System (WAS). WAS accordingly sets the threat level of the network. Based on this level, MAPS selects the most optimum parameters for the entire IDS to combat against the propagating worm. The MAPS architecture maintains the system performance by constantly evaluating three metrics, namely False Negative Avoidance, False Positive Avoidance, and Performance Overhead. Extensive experiments, using real network traffic and a recently proposed worm detection system, demonstrate that MAPS is capable of advising an IDS with optimum parameter values to effectively and promptly hinder further propagation of worms.

Combating against internet worms in large‐scale networks: an autonomic signature‐based solution

“…The proposed system, which is an extension of works presented in References [8,9], automatically detects novel worms through an anomaly analysis-based module. The newly detected worms are used to automatically generate the signature for the propagating worm.…”
