Available in PDF, EPUB and Kindle. Book excerpt: Every day, people interact with numerous computer systems, networks, and services that require the exchange of sensitive data. However, the Internet is a highly distributed system operated by many different entities and as such should not be trusted by end users. Users, whether consumers or businesses, retain no control over how their information is routed among the many networks that comprise the Internet. Therefore, there is a strong need for cryptographic protocols to authenticate, verify trust, and establish a secure channel for exchanging data. This chapter presents a series of projects and demonstrations for systems and networking professionals who want to increase their comprehension of security concepts and protocols. The material presented here is derived from existing courses taught by the authors in the areas of cryptography, network security, and wireless security.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless physical layer security approaches can prevent eavesdropping without upper layer data encryption. However, such techniques are hampered by time-varying wireless channel conditions and they are typically feasible only when the legitimate partners in the Wyner’s wire-tap channel model have an advantage over the source-eavesdropper channels. Node cooperation is an effective strategy to overcome this challenge and enhance the performance of secure wireless communications. This chapter addresses secure wireless communications of a source-destination pair with the help of multiple cooperating amplify-and-forward relays in the presence of one or more eavesdroppers. The role of channel fading is characterized in terms of average (ergodic) secure communication rates. Overall, this work establishes the utility of node cooperation for improving secure wireless communications and provides a unified analytical framework for assessing the ergodic secrecy rates of cooperative amplify-and-forward relay networks in a generalized fading environment with independent but non-identically distributed channel fading statistics.

Available in PDF, EPUB and Kindle. Book excerpt: Providing data security in the optical layer enables low latency data encryption and enlarges the capacity for secure data transmission. As the demand for both secure and high speed transmission grows dramatically, secure data transmission is pushing the requirements for processing speed and network capacity. As fiber-optic systems form the backbone of communication networks, optical approaches for protecting the network security increases the available capacity of the network. Moreover, compared to electric circuits, fiber-optic systems are immune to electromagnetic interference and have high processing speeds. In this chapter, we discuss using fiber-optic-based techniques to defend against threats in the network, including optical encryption, optical code-division multiple access (CDMA), optical key distribution, optical steganography, anti-jamming, and optical chaos-based communication. These approaches are categorized by their different applications for protecting the properties of network security, including confidentiality, privacy, and availability.

Available in PDF, EPUB and Kindle. Book excerpt: Trustworthy systems are essential for critical operations—they ensure that reliability, usability, interoperability, and security are built into the systems, and that the systems deliver when they are most needed. There are environments where trustworthiness is an essential property in military, government, and civil domains. Examples include missile deployment control systems, the tax submission system of the federal government, and nuclear safety control systems. However, not many methods exist for the systematic engineering of trustworthy software systems. In this chapter we describe the application of the NFR Approach for designing a trustworthy software system. The NFR Approach, where NFR stands for “non-functional requirement,” treats trustworthiness as a goal to be achieved during the process of software development. The NFR Approach uses a structure called the Softgoal Interdependency Graph to capture the trustworthiness definition, depict architectural elements as softgoals, and rationalize the extent of trustworthiness in the design. Advantages of this approach include the ability to nurture consensus among multiple definitions of trustworthiness, capture design rationale, evaluate qualitatively the extent of trustworthiness achieved, and maintain historical records of design decisions. We apply the NFR Approach to design a trustworthy Phoenix system, which is a message-oriented middleware system used by the US Air Force.

Available in PDF, EPUB and Kindle. Book excerpt: Information security has become a key issue. Human resources, including all people working with information technology, play a significant role in information security issues. The key factor for human resources in relation to information security is awareness about threats, challenges, and risks lurking in the information exchange environment. Improving staff awareness of information security should be one of the significant, permanent goals in an organization’s information security policies. This chapter investigates information security awareness in terms of knowledge, attitude, and behavior. Research was carried out using a survey method. To evaluate the information security awareness of staff, we developed nine components. Seven independent variables—gender, education level, IT awareness, working experience, occupation, field, and job category—were also selected for developing the conceptual model. Results showed that, among the investigated variables, gender, IT awareness, occupation field, and job category had significant correlations to information security awareness.

Available in PDF, EPUB and Kindle. Book excerpt: Lack of security is a constant concern in open distributed systems. Because of this problem, many tools for evaluating vulnerabilities of networks, as well as for their protection, are being developed and largely deployed; for example, techniques for encryption, antivirus, firewall, and IDSs (Intrusion Detection Systems). Among these, there are IDSs that are increasingly conceived, designed, and implemented. Currently, IDSs are created using software agents. Although IDSs can provide intrusion detection and countermeasures against threats, they are subjected to attacks. Thus, it is necessary to ensure security for IDSs. This chapter proposes a framework for providing self-security, self-reliability of message exchange, self-reliability of components, and self-integrity for IDSs based on agents. The proposed solution is implemented as an extension of the IDS-NIDIA (Network Intrusion Detection System Based on Intelligent Agents), whose architecture has an intelligent agent society that communicates in a cooperative way in a distributed environment. Some tests show the applicability of the proposed solution.

Available in PDF, EPUB and Kindle. Book excerpt: In wireless ad hoc networks, most of the authentication protocols assume a single source of trust. However, in the presence of multiple trust sources (called source group in this chapter), it becomes difficult to design resource- (or energy-) efficient authentication protocols, especially for multicast/broadcast services, utilizing multiple trust sources at the same time. Some traditional authentication approaches may be extended and used for this purpose. However, the communication overhead, for example, may increase significantly in proportion to the number of trust sources. In this chapter, we propose a new scheme named as Multi-Source Authentication with Split-Join One-Way Key Chain (SOKC). In this new technique, the communication overhead is small and constant, and the memory requirement at the verifier node is also minimal. The source group node needs to store n keys, where n represents the key chain length, which may be a reasonable requirement considering that the trust sources usually have more resources compared to other regular node(s) in the network (e.g., base stations in wireless sensor networks).

Available in PDF, EPUB and Kindle. Book excerpt: The need for well-trained Information Security and Assurance (ISA) professionals, as well as general information security awareness, has increased considerably in the last decade and shows no sign of slowing. To address this need, both industry and academia have been driven to innovative approaches. The use of digital games and game mechanics to further education has received growing attention and respect in the last several years. There is strong evidence that thoughtful employment of gaming elements can improve motivation and understanding. This paper provides a broad background on the topics of game-based learning, gamification, and serious games. Further, it describes our ongoing approach to developing and promoting digital games for information security awareness, including two game designs and a gamification system architecture.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
