Book Description :

Nearly every business depends on its network to provide information services to carry out essential activities, and network intrusion attacks have been growing increasingly frequent and severe. When network intrusions do occur, it’s imperative that a thorough and systematic analysis and investigation of the attack is conducted to determine the nature of the threat and the extent of information lost, stolen, or damaged during the attack. A thorough and timely investigation and response can serve to minimize network downtime and ensure that critical business systems are maintained in full operation. Network Intrusion Analysis teaches the reader about the various tools and techniques to use during a network intrusion investigation. The book focuses on the methodology of an attack as well as the investigative methodology, challenges, and concerns. This is the first book that provides such a thorough analysis of network intrusion investigation and response. Network Intrusion Analysis addresses the entire process of investigating a network intrusion by: *Providing a step-by-step guide to the tools and techniques used in the analysis and investigation of a network intrusion. *Providing real-world examples of network intrusions, along with associated workarounds. *Walking you through the methodology and practical steps needed to conduct a thorough intrusion investigation and incident response, including a wealth of practical, hands-on tools for incident assessment and mitigation.

Book Description :

“Practical Intrusion Analysis provides a solid fundamental overview of the art and science of intrusion analysis.” –Nate Miller, Cofounder, Stratum Security The Only Definitive Guide to New State-of-the-Art Techniques in Intrusion Detection and Prevention Recently, powerful innovations in intrusion detection and prevention have evolved in response to emerging threats and changing business environments. However, security practitioners have found little reliable, usable information about these new IDS/IPS technologies. In Practical Intrusion Analysis, one of the field’s leading experts brings together these innovations for the first time and demonstrates how they can be used to analyze attacks, mitigate damage, and track attackers. Ryan Trost reviews the fundamental techniques and business drivers of intrusion detection and prevention by analyzing today’s new vulnerabilities and attack vectors. Next, he presents complete explanations of powerful new IDS/IPS methodologies based on Network Behavioral Analysis (NBA), data visualization, geospatial analysis, and more. Writing for security practitioners and managers at all experience levels, Trost introduces new solutions for virtually every environment. Coverage includes Assessing the strengths and limitations of mainstream monitoring tools and IDS technologies Using Attack Graphs to map paths of network vulnerability and becoming more proactive about preventing intrusions Analyzing network behavior to immediately detect polymorphic worms, zero-day exploits, and botnet DoS attacks Understanding the theory, advantages, and disadvantages of the latest Web Application Firewalls Implementing IDS/IPS systems that protect wireless data traffic Enhancing your intrusion detection efforts by converging with physical security defenses Identifying attackers’ “geographical fingerprints” and using that information to respond more effectively Visualizing data traffic to identify suspicious patterns more quickly Revisiting intrusion detection ROI in light of new threats, compliance risks, and technical alternatives Includes contributions from these leading network security experts: Jeff Forristal, a.k.a.

Book Description :

Achieving complete and accurate cyber situation awareness (SA) is crucial for security analysts to make right decisions. A large number of algorithms and tools have been developed to aid the cyber security analysis, such as vulnerability analysis, intrusion detection, network and system monitoring and recovery, and so on. Although these algorithms and tools have eased the security analysts work to some extent, their knowledge bases are usually isolated from each other. Its a very challenging task for security analysts to combine these knowledge bases and generate a wholistic understanding towards the enterprise networks real situation.To address the above problem, this paper takes the following approach. 1) Based on existing theories of situation awareness, a Situation Knowledge Reference Model (SKRM) is constructed to integrate data, information, algorithms/tools, and human knowledge into a whole stack. SKRM serves as an umbrella model that enables e ective analysis of complex cyber-security problems. 2) The Bayesian Network is employed to incorporate and fuse information from di erent knowledge bases. Due to the overwhelming amount of alerts and the high false rates, digging out real facts is di cult. In addition, security analysis is usually bound with a number of uncertainties. Hence, Bayesian Networks is an e ective approach to leverage the collected evidence and eliminate uncertainties.With SKRM as the guidance, two independent security problems are identified: the stealthy bridge problem in cloud and the zero-day attack path problem. This paper will demonstrate how these problems can be analyzed and addressed by constructing proper Bayesian Networks on top of di erent layers from SKRM.First, the stealthy bridge problem. Enterprise network islands in cloud are expected to be absolutely isolated from each other except for some public services. However, current virtualization mechanism cannot ensure such perfect isolation. Some stealthy bridges may be created to break the isolation due to virtual machine image sharing and virtual machine co-residency. This paper proposes to build a cloud-level attack graph to capture the potential attacks enabled by stealthy bridges and reveal possible hidden attack paths that are previously missed by individual enterprise network attack graphs. Based on the cloud-level attack graph, a cross-layer Bayesian network is constructed to infer the existence of stealthy bridges given supporting evidence from other intrusion steps.Second, the zero-day attack path problem. A zero-day attack path is a multi- step attack path that includes one or more zero-day exploits. This paper proposes a probabilistic approach to identify the zero-day attack paths. An object instance graph is first established to capture the intrusion propagation. A Bayesian network is then built to compute the probabilities of object instances being infected. Connected through dependency relations, the instances with high infection probabilities form a path, which is viewed as the zero-day attack path.

Book Description :

There is increasing pressure to protect computer networks against unauthorized intrusion, and some work in this area is concerned with engineering systems that are robust to attack. However, no system can be made invulnerable. Data Analysis for Network Cyber-Security focuses on monitoring and analyzing network traffic data, with the intention of preventing, or quickly identifying, malicious activity. Such work involves the intersection of statistics, data mining and computer science. Fundamentally, network traffic is relational, embodying a link between devices. As such, graph analysis approaches are a natural candidate. However, such methods do not scale well to the demands of real problems, and the critical aspect of the timing of communications events is not accounted for in these approaches. This book gathers papers from leading researchers to provide both background to the problems and a description of cutting-edge methodology. The contributors are from diverse institutions and areas of expertise and were brought together at a workshop held at the University of Bristol in March 2013 to address the issues of network cyber security. The workshop was supported by the Heilbronn Institute for Mathematical Research.
