Recent years have seen a growing interest in computational methods based upon natural phenomena with biologically inspired techniques. The use of immune mechanisms in intrusion detection is an appealing concept. This paper reviews and assesses the analogy between the human immune system and intrusion detection systems. We show how immune metaphors can be used efficiently to build intrusion detection...
In recent years, the network attack become more and more widespread and difficult in against. The traditional technique, such as Firewall is good, but when malicious traffic originates from inside network or enters through a hole in the firewall you may need another line of defense to protect you. This is a article introducing the concepts of IDS, what they do, the functions they serve, the classification...
To protect SIP communication networks from attacks, especially flooding attacks like denial-of-service or message spam, intrusion detection systems (IDS) are deployed at the ingress point of the network to filter potential malicious traffic. A key issue of IDS performance is the operation of its firewall to block malicious user requests. Depending on the complexity of the firewall ruleset, filtering...
