Intrusion Detection Systems are fast-growing techniques for monitoring and garnering electronic evidences about suspicious activities that signify threats to computer systems. Generally, these mechanisms overwhelmingly describe and record patterns of suspicious packets as alerts in the form of intrusion logs. Thereafter, analysts must subsequently validate the content of each intrusion log to ascertain...
In recent years, the security issues on computer networks have become one of the primary concerns because the pervasiveness of computer technology has rendered computer networks to be more vulnerable to attacks than ever before. It is necessary to take corrective actions in the process of detecting surreptitious attacks to ensure proper safety of the entire system. However, effective post-intrusive...
With the rapid expansion of computer networks during the past few years, security has become a crucial issue for modern computer systems. A new idea challenging the classical self/non-self viewpoint has become popular amongst immunologists. It is called the danger theory. The new theory suggests that the immune system reacts to threats based on the correlation of various (danger) signals and it provides...
Computer networks have added new dimensions to the global communication. But intrusions and misuses have always threatened the secured data communication over networks. Consequently, network security has come into issue. Now-a-days intrusion detection systems play an important role in security infrastructures. Intrusions typically start with intruders infiltrating a network through a vulnerable host...
Computer networks are one of those unique gifts of modern science which enriched human life with the blessing of global connectivity. But as the network advanced, intrusions and misuses followed. Consequently, network security has come into issue. Now-a-days intrusion detection systems have become a standard component in security infrastructures. Intrusions typically start with intruders infiltrating...
With the progression of time, we have been blessed with the gifts of science. Computer networks are one of those gifts. But as the network proceeded, intrusions and misuses followed. Consequently, network security has come to the fore front and has become one of the most important issues. Now-a-days intrusion detection systems have become a standard component in security infrastructures. Intrusions...
An artificial immune system (ARTIS) enlightened by the biological immune system is emerging as a new field of computation intelligence research. At present, it showed us many properties after the research to the immune system, including distributed computation, self-organization and lightweight, which were discovered to meet the requests of ARTIS. So the Immunology applied to the intrusion detection...
The rapid proliferation of computer networks has changed the prospect of network security. An easy accessibility condition cause computer networkpsilas vulnerable against several threats from hackers. Threats to networks are numerous and potentially devastating. Up to the moment, researchers have developed Intrusion Detection Systems (IDS) capable of detecting attacks in several available environments...
Recently network intrusion detection is one of the hottest research topics. Existing network-based Intrusion Detection System (IDS) has drawbacks in many aspects, among of which the two outstanding problems are the high ratio of false alarms and the lack of self-adaptation. The powerful information processing capabilities of the biological immune system, such as feature extraction, pattern recognition,...
Recent security incidents and analysis have demonstrated that current intrusion detection systems (1DS) to some attacks are no longer feasible. Implementing an effective intrusion detection capability is an elusive goal, not solved easily or with a single mechanism. However, we argue that "SoftMan" (SM) technology goes a long way toward realizing the ideal behavior desired in an intrusion...
A honeypot is a type of information system that is used to obtain information on intruders in a network. When a honeypot is deployed in front of a firewall, it can serve as an early warning system. When deployed behind the firewall, it can serve as part of a defense-in-depth system and can be used to detect attackers who bypass the firewall and the intrusion detection system (IDS) or threats from...
