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.

In this chapter, we discuss the threats, challenges, and guidance associated with securing an organization’s core IT infrastructure at the network, host, and application levels in the cloud. According to the best knowledge of the authors, up to now, there are no research with this perspective on cloud security in the literature. This chapter represents our first discussion of this infrastructure security in the context of SPI service delivery models (SaaS, PaaS, and IaaS). Non-information security professionals are cautioned not to simply equate infrastructure security to infrastructure-as-a-service (IaaS) security. Although infrastructure security is more highly relevant to customers of IaaS, similar consideration should be given to providers’ platform-as-a-service (PaaS) and software-as-a-service (SaaS) environments, since they have ramifications to customer threat, risk, and compliance management. Another dimension is the cloud business model (public, private, and hybrid clouds), which is orthogonal to the SPI service delivery model; what we highlight is the relevance of discussion points as they apply to public and private clouds. When discussing public clouds, the scope of infrastructure security is limited to the layers of infrastructure that move beyond the organization’s control and into the hands of service providers (i.e., when responsibility to a secure infrastructure is transferred to the cloud service provider [CSP], based on the SPI delivery model). Information in this chapter is critical for customers in gaining an understanding of what security a CSP provides and what security the customer is responsible for providing. This chapter discusses conceptual issues, basic requirements, and practical suggestions for designing dynamically configured security infrastructure provisioned on demand as part of the cloud-based infrastructure. We end this chapter by describing general-use cases for provisioning cloud infrastructure that provide bases for defining security infrastructure requirements.

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.

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.

In this chapter we present a novel approach for securing financial XML transactions using an effective and intelligent fuzzy classification technique. Our approach defines the process of classifying XML content using a set of fuzzy variables. Upon fuzzy classification phase, a unique value is assigned to a defined attribute named "ImportanceLevel." Assigned value indicates the data sensitivity for each XML tag. The model also defines the process of securing classified financial XML message content by performing element-wise XML encryption on selected parts defined in fuzzy classification phase. Element-wise encryption is performed using symmetric encryption using AES algorithm with different key sizes. A key size of 128-bit is being used on tags classified with "Medium" importance level; a key size of 256-bit is being used on tags classified with "High" importance level. An implementation has been performed on a real-life environment using an online banking system to demonstrate system efficiency. Our experimental results verified tangible enhancements in encryption efficiency, processing-time reduction, and resulting XML message sizes.

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.

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.

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.
