Intrusion Detection And Correlation

Details how intrusion detection works in network security with comparisons to traditional methods such as firewalls and cryptography Analyzes the challenges in interpreting and correlating Intrusion Detection alerts

This book constitutes the refereed proceedings of the International Conference on Advances in Security of Information and Communication Networks, Sec Net 2013, held in Cairo, Egypt, in September 2013. The 21 revised full papers presented were carefully reviewed and selected from 62 submissions. The papers are organized in topical sections on networking security; data and information security; authentication and privacy; security applications.

To defend against computer and network attacks, multiple, complementary security devices such as intrusion detection systems (IDSs), and firewalls are widely deployed to monitor networks and hosts. These various IDSs will flag alerts when suspicious events are observed. This book is an edited volume by world class leaders within computer network and information security presented in an easy-to-follow style. It introduces defense alert systems against computer and network attacks. It also covers integrating intrusion alerts within security policy framework for intrusion response, related case studies and much more.

This book constitutes the refereed proceedings of the 21st Conference of the Canadian Society for Computational Studies of Intelligence, Canadian AI 2008, held in Windsor, Canada, in May 2008. The 30 revised full papers presented together with 5 revised short papers were carefully reviewed and selected from 75 submissions. The papers present original high-quality research in all areas of Artificial Intelligence and apply historical AI techniques to modern problem domains as well as recent techniques to historical problem settings.

The Navy's Intrusion Detection process is currently reactive in nature. It is designed and programmed to detect and provide alerts to the Fleet Information Warfare Center (FlWC) of suspicious network activity while it is in progress, as well as to record/store data for future reference. However, the majority of activity taking place within and across Naval networks is legitimate and not an unauthorized activity. To allow for efficient access and utilization of the information systems sharing the network the Intrusion Detection Systems must be set at a level that filters out activity deemed as normal or non%hostile, while still providing an appropriate level of security. With this filtering in place an IDS system will not register all suspicious activity, and may not detect mild and seemingly harmless activity. When increasing security, limits must be imposed upon access. This thesis examines FIWC network incident data from 1999 to see if a correlation can be drawn between United States visibility in the foreign media during 1999 and the occurrence of suspicious network incidents. A positive correlation may provide advance-warning indicators that could lead to the development of a procedure for increasing security posture based on the current environment. These indicators would provide a more proactive method of defense, significantly reduce potential damage caused by hostile network incidents and provide for more efficient network activity.

Network Intrusion Detection and Prevention: Concepts and Techniques provides detailed and concise information on different types of attacks, theoretical foundation of attack detection approaches, implementation, data collection, evaluation, and intrusion response. Additionally, it provides an overview of some of the commercially/publicly available intrusion detection and response systems. On the topic of intrusion detection system it is impossible to include everything there is to say on all subjects. However, we have tried to cover the most important and common ones. Network Intrusion Detection and Prevention: Concepts and Techniques is designed for researchers and practitioners in industry. This book is suitable for advanced-level students in computer science as a reference book as well.
