In this paper, we in introduce a specification based intrusion detection model for detecting attacks on routing protocols in MANETs. Intrusion detection is a viable approach to enhancing the security of existing computers and networks. Briefly, an intrusion detection system monitors activity in a system or network in order to identify ongoing attacks. Intrusion detection techniques can be class...

By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...

Security term in mobile ad hoc networks has several aspects because of the special specification of these networks. In this paper a distributed architecture was proposed in which each node performed intrusion detection based on its own and its neighbors’ data. Fuzzy-neural interface was used that is the composition of learning ability of neural network and fuzzy Ratiocination of fuzzy system as...

Specification-based intrusion detection, where manually specified program behavioral specifications are used as a basis to detect attacks, have been proposed as a promising alternative that combine the strengths of misuse detection (accurate detection of known attacks) and anomaly detection (ability to detect novel attacks). However, the question of whether this promise can be realized in pract...

An Intrusion Detection System (IDS) protects computer networks against attacks and intrusions, in combination with firewalls and anti-virus systems. An IDS is therefore a crucial element of a network security posture. One class of IDS is called signature-based network IDSs as they monitor network traffic, looking for evidence of malicious behavior as specified in attack descriptions (referred t...

Due to the prevalence of Wireless Sensor Networks (WSNs) in the many mission-critical applications such as military areas, security has been considered as one of the essential parameters in Quality of Service (QoS), and Intrusion Detection System (IDS) is considered as a fundamental requirement for security in these networks. This paper presents a lightweight Intrusion Detection System to prote...

increasing the popularity of sip based services (voip, iptv, ims infrastructure) lead to concerns about its ‎security. the main signaling protocol of next generation networks and voip systems is session initiation protocol ‎‎(sip). inherent vulnerabilities of sip, misconfiguration of its related components and also its implementation ‎deficiencies cause some security concerns in sip based infra...
