The Internet’s relatively unfettered transmission of information risks exposing individuals to extremist content. Using online survey data (N = 768) of American youth and young adults, we examine factors that bring individuals into contact with online material advocating violence. Combining aspects of social structure-social learning theory with insights from routine activity theory, we find that exposure to violence-advocating materials is positively correlated with online behaviors, including the use of social media platforms and the virtual spaces individuals frequent. Target antagonism is also correlated with exposure to violence-advocating materials, but guardianship and online and offline associations are not. Finally, feelings of dissatisfaction with major social institutions and economic disengagement are associated with exposure to violent materials online.

This thesis explores the nature of cyber security at the beginning of the 21st century. In the current security paradigm, security strategies based on anticipatory governance have become essential in the management of the constantly changing cyber security environment. Thus, this thesis aims to understand security strategies and governance introduced in the European region. The increased dependency on cyber space is visible in all public private sectors and governmental operations, as well as communications between groups and individuals. As a result, cyber attacks on public and private entities are increasing. This requires a security framework that is flexible and establishes different types of security cooperation to manage the widespread cyber risks. This is essential to the development of security strategies, governance forms, practices, and guidelines for enhancing resilience and preparedness towards cyber risks. Therefore, I am examining cyber security through the lenses of nodal governance and governmentality, which enables me to understand European cyber security strategies and governance forms developed by the Council of Europe, the European Union, and the North Atlantic Treaty Organization. To analyse existing strategies and governance forms, I have used two critical security schools, the Copenhagen School and the Paris School, which cover different aspects of the security agenda. The thesis develops a substantive analytical framework through two case studies, namely cyber security and cyber terrorism. The findings in this thesis identifies problem areas, such as the complexity of the nodal system, the legislative lacuna, reliance on different governance forms, transparency and accountability, and types of anticipatory governance and regulatory practices.

Attacks on computer systems for both criminal and political purposes are on the rise in both the United States and around the world. Foreign terrorist organizations are also developing information technology skills to advance their goals. Looking at the convergence of these two phenomena, many prominent security experts in both government and private industry have rung an alarm bell regarding the potential for acts of cyber-terrorism. However, there is no precise definition of cyber-terrorism under United States law or in practice among cyber-security academicians. The lack of a common starting point is one of the reasons existing law fails to directly address cyberterrorism. This paper furnishes a lexicon of cyber-related malicious activities and argues for a common working definition of cyber-terrorism. This definition can be both incorporated into current counter-terror legislation and used by government agencies to combat cyberterrorism. This paper arrives at that definition by analyzing the various definitions proposed by security experts and those in use by governmental organizations. This paper builds on these definitions to arrive at a new definition that is at once broad enough to cover the potentially unique effects of a weapon of cyber-terrorism, while narrow enough to exclude computer network attacks that are relatively minor in nature. Second, analyzing several recent cyber attacks, this paper finds that, while we have not yet faced a “cyber 9/11,” computer network attacks for political purposes are on the rise and becoming increasing complex. Third, this paper analyzes current law related to both cyber-crimes and terrorism, finding that while these laws are applicable in many instances, they fall short in adequately focusing on the most important factor when addressing cyber-terrorism: prevention. This paper concludes by recommending that cyber-terrorism, as defined in this paper, be incorporated into some of our most frequently used laws to combat terrorism.

The acceleration of the historical tempo and the move from hierarchical to networked conceptions of power is disintegrating the mechanisms of control and political representation at the disposal of the state. The upshot of this is that ‘resistance confronts domination, empowerment reacts against powerlessness, and alternative projects challenge the logic embedded in the new global order’ (Castells 1997, 69). These reactions and mobilisations, often take ‘unusual formats and proceed through unexpected ways’ (Castells 1997, 69). This chapter deals with one such alternative project. It is a preliminary empirical analysis of the adoption by the Lebanese-based terrorist group Hizbollah (Party of God) of a strategy of cybercortical warfare. In his introduction to the Vintage edition of Covering Islam (1997), Edward Said refers to the ‘information wars that have gone on since 1948 around the whole question of the Middle East’ (p. xxi). He is particularly concerned with the way in which Hizbollah ‘who identify themselves and are perceived locally as resistance fighters’ are ‘commonly referred to in the American media as terrorists’ (p. xiii). Hizbollah are one of a number of groups that have utilized the Internet ‘to produce and articulate a conscious and forceful self-image’ (Said: 66) of themselves not as terrorists, but as resistance fighters and statesmen. The major focus of this chapter is the way in which Hizbollah have wielded the Internet as a weapon in their information war. As will be demonstrated, the group’s collection of Web sites is targeted not at Lebanese or Palestinian audiences, but at the Israeli population and global publics. For this reason, the chapter represents a case study of the possibilities of the new technology, discussed and defined by this chapter as ‘cybercortical warfare’.

The US electricity infrastructure uses Industrial Control Systems (ICS) to oversee its operations. These systems are connected online for better efficiency, making them susceptible to cyberattacks. Current research has extensively addressed ICS vulnerabilities that can be exploited by cybercriminals. Vulnerabilities, however, are only one of the many factors influencing offender decision-making in cyberattacks. Furthermore, numerous conceptions of threats, vulnerabilities, and consequences exist, which further complicate ICS security assessments. This exploratory study therefore has two main goals. First, it seeks to compare industry and hacker perceptions on electricity ICS threats, vulnerabilities, and consequences. Second, it seeks to identify a broader set of factors that influence offender decision-making in ICS cyberattacks.

The digital era of information technology appears to be a new space and place for the Indonesian Shiite communities to express their existence and conceal their “cloak” in the country.. Internet, websites, Facebook pages, Blog spots, and Twitter are tilized by these Shiite followers and supporters to show their presence, activities, interactivity, and thoughts about Islam. Responding to those Shia media, the anti-Shia movements such as the fundamentalist Sunnis, the Wahabi-Salafi’s, the Wahabi-Takfiri’s supporters have created their online publications and fan pages to counter those Shia’s publications. The online media battles on sectarianism issue then have sparked in the cyberspace of Indonesia in the last three years. Using a critical cultural studies tradition and textual approach, this study tries to examine the rise of Shia and anti-Shia online media as well as the meanings and contexts in which violent actions occurred amongst the Sunni-Shia Muslim communities on it. This paper also attempts to look closely at the way the media writes, covers, and build opinions and attitude to inform and provoke the public.
