Alarm Clustering for Intrusion Detection Systems in Computer Networks

Until recently, network administrators manually arranged alarms produced by Intrusion Detection Systems (IDSs) to attain a highlevel description of threats. As the number of alarms is increasingly growing, automatic tools for alarm clustering have been proposed to provide such a high level description of the attack scenario. In addition, it has been shown that effective threat analysis require ...

Alarm Reduction and Correlation in Intrusion Detection Systems

Large Critical Complex Infrastructures are increasingly dependent on IP networks. Reliability by redundancy and tolerance are an imperative for such dependable networks. In order to achieve the desired reliability, the detection of faults, misuse, and attacks is essential. This can be achieved by applying methods of intrusion detection. However, in large systems, these methods produce an uncont...

Intrusion Detection Alarm Correlation: a Survey

It is 17 years since Dorothy Denning proposed the first intrusion detection model. These systems have evolved rapidly from that model to present alarm correlation methods. Up to the moment, researchers have developed Intrusion Detection Systems (IDS) capable of detecting attacks in several environments. A boundlessness of methods for misuse detection as well as anomaly detection has been applie...

False alarm minimization techniques in signature-based intrusion detection systems: A survey

A network based Intrusion Detection System (IDS) gathers and analyzes network packets and report possible low level security violations to a system administrator. In a large network setup, these low level and partial reports become unmanageable to the administrator resulting in some unattended events. Further it is known that state of the art IDS generate many false alarms. There are techniques...
