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 :

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 Description :

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.

Book Description :

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.

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 :

Advances in Web technologies have brought about a massive increase in online businesses, but security has significantly lagged behind. We and others argue that governments can and should play a major role in providing a reliable and secure environment for online businesses because they have a major stake in growing the economy. Our finding from previous research indicates that security is usually overlooked; it comes as an afterthought or is perceived from a purely technical dimension. This study attempts to describe and analyze the current role of the government of Jordan in facilitating the security of e-business. Our starting premise is that governments should recognize the full range of socio-technical implications that security may have on the adoption of e-business. This can be achieved by understanding the real security needs and concerns of the various stakeholders at the different e-business stages and then aligning them to its policy and plans. Moreover, we argue that in order for the government to be an effective partner in developing a secure e-business environment, legislating laws and regulations is insufficient; instead, governments must increase security education and awareness, ensure compliance with security standards and regulations, and protect the country’s critical ICT infrastructure.

Book Description :

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.

Book Description :

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.

Book Description :

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.

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.

Book Description :

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.

Book Description :

Deploying an appropriate collection of information security countermeasures in an organization should result in high-level blocking power against existing threats. In this chapter, a new knapsack-based approach is proposed for finding out which subset of countermeasures is the best at preventing probable security attacks. In this regard, an effectiveness score is defined for each countermeasure based on its mitigation level against all threats. Organizations are always looking for more effective low-cost solutions, so another consideration is that the implementation cost of the selected countermeasure portfolio should not exceed the allocated budget. Following the knapsack idea, the implementation cost of each countermeasure and its effectiveness, defined as inputs and the best subset, are chosen with respect to budget limits. Our results are compared with similar research and recommend the same countermeasure portfolio.

Book Description :

Man-in-the-browser is a Trojan that infects a Web browser. A Trojan has the ability to modify Web pages and online transaction content, or insert itself in a covert manner, without the user noticing anything suspicious. This chapter presents a study of several man-in-the-browser attacks that tamper with the user’s transactions and examines different attack vectors on several software layers. We conclude that there are many possible points of attack on different software layers and components of a Web browser, as the user’s transaction data flows through these layers. We also propose some countermeasures to mitigate these attacks. Our conceptual solution is based on cryptographic identification and integrity monitoring of software components.

Book Description :

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.

Book Description :

CCTV systems are broadly deployed in the present world. Despite this, the impact on anti-social and criminal behavior has been minimal. To ensure in-time reaction for intelligent surveillance, it is a fundamental task for real-world applications to determine the trajectory of any interested subject. However, precise video information for subjects (e.g., face information) is not always available, especially in zones without cameras. In these cases, we have to use event reasoning techniques to combine all kinds of dynamic information (e.g., video analytics, card reading results, etc.) as well as background information (e.g., topological information). This chapter hence proposes an event reasoning based framework for trajectory tracking. The main idea is to use inference rules to infer the passage of a subject when there is not enough dynamic information. We demonstrate the significance and usefulness of our framework with a simulation experiment, which shows better performance than using dynamic information only.

Book Description :

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.

Book Description :

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 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 :

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.
