Book Description
In this chapter we propose a method for the extraction of data from network flow and a contextual separation of partial connections, using a set of network metrics that create a signature defining the connection behavior. We begin with defining the input dataset of captured communication and the process of extracting metrics from separated connections. Then we define the set of metrics included in the final behavioral signature. The second part of the chapter describes experiments performed with a state-of-the-art set of network metrics, with comparison to our proposed experimental set. The chapter concludes with the results of our experiments.

Book Description
This chapter discusses the problematic intersection of risk management, mission assurance, security, and information systems through the illustrative example of the United States (US) Department of Defense (DoD). A concise history of systems security engineering (SSE) is provided with emphasis on recent revitalization efforts. Next, a review of established and emerging SSE methods, processes, and tools (MPT) frequently used to assess and manage critical shortfalls in the development and fielding of complex information-centric systems is provided. From this review, a common theme emerges—the need for a holistic multidisciplinary approach that addresses people, processes, and technologies to manage system complexity, while providing cost-effective security solutions through the use of established systems engineering techniques. Multiple cases and scenarios that promote the discovery and shared understanding of security solutions for complex systems by those trained in the art and science of systems engineering, information security, and risk management are demonstrated.

Book Description
Nowadays, cybersecurity makes headlines across the media and in companies, blogs, social networks, among other places. The Internet is a wild cyberspace, an arena for commercialization, consumerism, business, and leisure, to name a few activities. Networks, populations, and nations around the world, now interconnected through the Internet, rely on it for their daily lives. But some Internet users have learned to take advantage of vulnerable systems and of Internet technologies for their own good, sending out spam, phishing, data breaches, botnets, and other threats. An underground criminal network has emerged, creating complex malware kits for several purposes. “Hacktivism” has become a popular term with many supporters worldwide, but cyberwarfare is now on the rise, gaining more and more attention from nation-states. This chapter provides a quick overview of these topics, discussing them in a timely manner, referencing key events from the past while focusing on the present day.

Book Description
Memory errors, such as stack and integer vulnerabilities, still rank among the top most dangerous software security issues. Existing protection techniques, like Address Space Layout Randomization and Stack-Smashing Protection, prevent potential intrusions by crashing applications when anomalous behaviors are detected. Unfortunately, typical networking server architectures, such those used on Web servers ones, limit the effectiveness of such countermeasures. Since memory error exploits usually rely on highly specific processor characteristics, the same exploit rarely works on different hardware architectures. This paper proposes a novel strategy to thwart memory error exploitation by dynamically changing, upon crash detection, the variant executing the networking server. Required software diversification among variants is obtained using off-the-shelf cross-compilation suites, whereas hardware diversification relies on processor emulation. The proposed case study shows the feasibility and effectiveness of the approach to reduce the likelihood, and in some cases even prevent the possibility, of exploiting memory errors.

Book Description
Security assurance is the guarantee provided with regard to access control, security privileges, and enforcement over time as users interact with an application. For a big-data application that shares and exchanges information from multiple sources in different formats, security assurance must reconcile local security capabilities to meet stakeholder needs. This chapter presents a role-based access control (RBAC) approach to modeling a global security policy and generating an enforcement mechanism for a big-data application by integrating the local policies of the sources, which are assumed to communicate via XML, the de facto standard for information sharing/exchange. Towards this goal, the Unified Modeling Language (UML) is extended to define new diagrams to capture XML for RBAC security and for policy modeling. To illustrate, we use a big-data application in law enforcement for motor vehicle crashes, showing how global security can be achieved in a repository that links different crash data repositories from multiple sources.

Book Description
In this chapter we state that metrics and indicators are key, reusable organizational assets for providing suitable data and information for analyzing, recommending, and ultimately making decisions. In a nutshell, the metric represents the specification of a measurement process that transforms an entity attribute (i.e., the input; such as a security property) into a measure (i.e., the output, which is data), and the (elementary) indicator is the specification of an evaluation process, which has as input a metric’s measure and produces an indicator value (i.e., information). There is abundant literature on ICT security and risk assessment, but very often basic issues such as why, what, how, when, who, and where to measure and evaluate are weakly intertwined and specified. One hypothesis in our research is that, without appropriate recorded metadata of information needs, attributes, metrics, and indicators, it is difficult to ensure that measure and indicator values are repeatable and consistently comparable among an organization’s measurement and evaluation (M&E) projects. We show the added value of metrics and indicators as informational resources for M&E processes, illustrating a couple of them from a system security practical case.

Book Description
This chapter introduces natural language information assurance and security (NL IAS), a new front in information security effort enabled by applying the Ontological Semantics approach to natural language processing to the existing and new applications. It reviews the earlier (1999–2004) application implementations, their increasing and expanding computational semantic foundations, and new advances (2010–2013). The thrust of the chapter is that access to comprehensive natural language meaning—incrementally approximating human understanding and based on the dedicated semantic resources, the language independent property rich ontology, and language-specific lexicons—is necessary for the design and implementation of high precision applications in authenticating and protecting natural language files.
