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: 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 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.

Book excerpt: In order to increase the accuracy of intrusion detection rate and reduce the false alarm rate for cyber-security analysis, attack correlation has become an indispensable component in most intrusion detection systems. However, traditional intrusion detection techniques often fail to handle the complex and uncertain network attack correlation tasks. We propose the creation of semantic networks that build relationships among network attacks and assist in automatically identifying and predicting related attacks. Also, our method can increase the precision in detecting probable attacks. Experimental results show that our semantic network, using the Anderberg similarity measure, performs better in terms of precision and recall compared to existing correlation approaches in the cyber-security domain.

Book excerpt: Educational tools related to firewalls and firewall configurations are central to the development of cybersecurity education, due to the integral role firewalls play in this field. To assess the current state of firewall education, we developed a set of criteria that educational exercises should meet. They should be competitive, interactive, extensible, and approachable. These criteria were then applied to three existing firewall exercises in order to gauge their strengths and weaknesses. With that information in mind, we then looked to emerging trends in firewalls and firewall education. We found that many of the emerging trends align with our criteria, but diverge from them in other important ways.

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.

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: 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: We propose a network-type scheme of private information retrieval, presented as a modification of the conventional setup, where the user is replaced with two users, the user-sender and the user-receiver. As a result of communication, the user-receiver becomes informed about the bit located at a certain position of the database, owned by the servers. Each server receives a query from the user-sender that contains information about the position in a hidden form and the server cannot disclose this position. On the basis of the query and the database, each server forms the replica, which is then transmitted to the user-receiver. By combining replicas, the user-receiver decodes the retrieved bit. We present a simple algebraic scheme where the communication complexity and the computational complexity are expressed as functions of the logarithm of the database size. The approaches allow extensions to the one-server scheme, the multi-scheme with noisy replicas of a fixed number of servers, and the authentication of a certain fragment of the database.

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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: The current mechanism implemented for Web session management implies exchanging session cookies between a Web application client (usually a browser) and a Web application server. Besides having privacy issues, the security of Web sessions can be affected by various reasons related to cookies. There are several vulnerabilities that threaten a Web application specifically related to cookies: theft, tampering, and/or forgery. Any of these vulnerabilities may favor session theft and/or unauthorized access using the identity of another user in the system. In this chapter, we present an alternative technique for management of Web sessions, where no session cookies are sent to clients while maintaining backward compatibility. As a result, the proposed technique is shown to avoid several specific vulnerabilities that affect the security of Web application sessions and users. The proposed mechanism works transparently for Web applications, and a proof of concept was successfully tested with Web applications based on different languages such as Php, Perl, Ruby, and Python.

Available in PDF, EPUB and Kindle. Book excerpt: Cyber-terrorism is common nowadays. There is a complex network of private and public organizations used in supervising the Internet. Even so, the complexity of the system is leading to an increase in the response time due to various bottlenecks in relation to information flow. As a result, a paradigm shift in security auditing in cyberspace is required. An approach based on intelligent agents may decrease the time needed to gather and process the basic information. A multi-agent system with the goal of helping the user, the security expert, and the security officer is presented in this chapter. The system will process local knowledge databases as well as external information provided by social networks, news feeds, and other forms of published information available on the Internet. An executive summary will be automatically generated and presented to the security chief of the organization using the system. Also, the system may provide advice to ordinary users when disputable decisions regarding computing node security must be made.

Book excerpt: Access control comprises a central concept in ICT security, leveraged for the protection of various resources, including systems, networks, applications, services, corporate assets, and information. It has also emerged as an important mechanism for the protection of personal data, resulting in a family of models referred to as privacy-aware access control. Due to the increasing complexity of the ICT ecosystem, various approaches have been proposed with the aim to provide expressive access control models and, in this context, Semantic Web technologies have also been leveraged. This chapter investigates the application of Semantic Web technologies in access control, highlighting the main trends in the area and outlining the most characteristic approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Over the years, many networks hosted by large companies or organizations have been crippled by intrusions launched with minimal effort. Such attacks have caused the loss of millions of dollars for the company and created serious security threats. As a result, network administrators and security experts across the globe have barricaded their networks with expensive Intrusion Detection Systems (IDS) to detect and take action in dealing with various network attacks. There is still a very challenging task to develop a cost-effective approach that can deal with network intrusions. Furthermore, large networks generate huge traffic data that serve as inputs for IDSes. In this chapter, we present a Network Intrusion Detection System (NIDS) built using Apache Hadoop and HStreaming, which can detect and alert administrators in real time. The system makes use of a simple yet versatile Naive Bayes classifier for predicting an attack. The experimental results show some promising outcomes.
