Analysis of intrusion detection systems

Performance Analysis of Wireless Intrusion Detection Systems

Wireless network security has a considerable attention in recent years. Several security efforts have been exerted to combat the wireless attacks, but unfortunately complete attack prevention at the first line of defense such as authentication, encryption, and firewall is not realistically attainable. Thus, the emphasis on detecting wireless attacks at a second line of defense, in the form of W...

Intrusion Detection Systems and Intrusion Prevention Systems

Evolving Intrusion Detection Systems

An Intrusion Detection System (IDS) is a program that analyzes what happens or has happened during an execution and tries to find indications that the computer has been misused. An IDS does not eliminate the use of preventive mechanism but it works as the last defensive mechanism in securing the system. This Chapter evaluates the performances of two Genetic Programming techniques for IDS namely...

Intrusion Detection Systems

Modern Intrusion Detection Systems

Intrusion detection systems (IDS) help detect unauthorized activities or intrusions that may compromise the confidentiality, integrity or availability of a resource. This paper presents a general overview of IDSs, the way they are classified and the different algorithms used to detect anomalous activities. It also describes the various approaches and the importance of IDSs in information security.
