IEEE 802.11 i Security and Vulnerabilities

Despite using a variety of comprehensive preventive security measures, the Robust Secure Networks (RSNs) remain vulnerable to a number of attacks. Failure of preventive measures to address all RSN vulnerabilities dictates the need for enhancing the performance of Wireless Intrusion Detection Systems (WIDSs) to detect all attacks on RSNs with less false positive and false negative rates

Network Intrusion Detection and Prevention Systems in Educational Systems : A case of Yaba College of Technology

Nwogu, Emeka Joshua. 2012. Network Intrusion Detection and Prevention Systems in Educational Systems - A case of Yaba College of Technology. Bachelor’s Thesis. Kemi-Tornio University of Applied Sciences. Business and Culture. Pages 66. Appendix 1. The objective of this thesis work is to put forward a solution for improving the security network of Yaba College of Technology (YCT). This work focuses on implementation of a network intrusion detection and prevention system (IDPS), due to constant intrusions on the YCT’s network. Various networks attacks and their mitigation techniques are also discussed, to give a clear picture of intrusions. The work will help the College’s administrators to become increasingly cautions of attacks and perform regular risk analyses. The research methodologies used in this work are descriptive and exploratory research. In addition, a questionnaire survey and interviews were used to collect data necessary for in-depth knowledge of the intrusions in the College. The choice of the research methods was found relevant for the current work. Furthermore, the researcher intended to gain an increased understanding of and provide a detailed picture of IDPS and the issues to consider when implementing the system. Network intrusion has been a security issue since the inception of the computer systems and the Internet. When breaking into a computer or network system, confidentiality, integrity and availability (CIA) are the three most aspect of security that are targets for intruders. The CIA, important aspects of security, and other network resources, need to be well protected using robust security devices. Based on the research tests and results, this thesis proposes implementation of IDPS on the College’s network, which is an essential aspect of securing information and network resources

Unified architecture of mobile ad hoc network security (MANS) system

In this dissertation, a unified architecture of Mobile Ad-hoc Network Security (MANS) system is proposed, under which IDS agent, authentication, recovery policy and other policies can be defined formally and explicitly, and are enforced by a uniform architecture. A new authentication model for high-value transactions in cluster-based MANET is also designed in MANS system. This model is motivated by previous works but try to use their beauties and avoid their shortcomings, by using threshold sharing of the certificate signing key within each cluster to distribute the certificate services, and using certificate chain and certificate repository to achieve better scalability, less overhead and better security performance. An Intrusion Detection System is installed in every node, which is responsible for colleting local data from its host node and neighbor nodes within its communication range, pro-processing raw data and periodically broadcasting to its neighborhood, classifying normal or abnormal based on pro-processed data from its host node and neighbor nodes. Security recovery policy in ad hoc networks is the procedure of making a global decision according to messages received from distributed IDS and restore to operational health the whole system if any user or host that conducts the inappropriate, incorrect, or anomalous activities that threaten the connectivity or reliability of the networks and the authenticity of the data traffic in the networks. Finally, quantitative risk assessment model is proposed to numerically evaluate MANS security

A Novel Cooperative Intrusion Detection System for Mobile Ad Hoc Networks

Mobile ad hoc networks (MANETs) have experienced rapid growth in their use for various military, medical, and commercial scenarios. This is due to their dynamic nature that enables the deployment of such networks, in any target environment, without the need for a pre-existing infrastructure. On the other hand, the unique characteristics of MANETs, such as the lack of central networking points, limited wireless range, and constrained resources, have made the quest for securing such networks a challenging task. A large number of studies have focused on intrusion detection systems (IDSs) as a solid line of defense against various attacks targeting the vulnerable nature of MANETs. Since cooperation between nodes is mandatory to detect complex attacks in real time, various solutions have been proposed to provide cooperative IDSs (CIDSs) in efforts to improve detection efficiency. However, all of these solutions suffer from high rates of false alarms, and they violate the constrained-bandwidth nature of MANETs. To overcome these two problems, this research presented a novel CIDS utilizing the concept of social communities and the Dempster-Shafer theory (DST) of evidence. The concept of social communities was intended to establish reliable cooperative detection reporting while consuming minimal bandwidth. On the other hand, DST targeted decreasing false accusations through honoring partial/lack of evidence obtained solely from reliable sources. Experimental evaluation of the proposed CIDS resulted in consistently high detection rates, low false alarms rates, and low bandwidth consumption. The results of this research demonstrated the viability of applying the social communities concept combined with DST in achieving high detection accuracy and minimized bandwidth consumption throughout the detection process
