Experts estimate that websites maintained by various Islamic extremists have increased to hundreds in recent years. Innovative operational capabilities enabled by Internet technology certainly pose serious challenges to U.S. counter-terrorism efforts. However, greater attention must be given to Islamic organizations that wage information campaigns, perpetuating resentment and discredit against the United States and her allies. While these sites may not openly call for violence, the sharing of common causes and goals with extremist organizations is worrisome. The repudiation of Western systems and global Islamization under the Shariah systems is often a transparent theme. The purpose of this thesis is to evaluate the effectiveness of these websites at attracting and engaging audiences to promote their cause by applying a web performance methodology commonly accepted in the commercial industry.

This study researches the varying threats that emanate from terrorists who carry their activity into the online arena. It examines several elements of this threat. First, it explores elements of virtual to virtual attacks. Second, it looks at threats against critical infrastructures that can be traced to online sources. Third, this thesis reports on ways that terrorists are using information technology such as the Internet for propaganda and communication purposes. Finally, it highlights the most crucial ways in which the United States government has responded to the problem. It concludes with a few recommendations for best practices for future engagement with varying aspects of cyberterrorism.

The bulk of this article is concerned with showing why computer hackers and terrorists are unlikely to form an unholy alliance to engage in so-called
cyberterrorism. The remainder of the paper examines why neither hacktivists nor crackers fall easily into the cyberterrorist category either.

This paper describes and discusses the process of secret communication known as steganography. The argument advanced here is that terrorists are unlikely to be employing digital steganography to facilitate secret intra-group communication as has been claimed. This is because terrorist use of digital steganography is both technically and operationally implausible. The position adopted in this paper is that terrorists are likely to employ low-tech steganography such as semagrams and null ciphers instead.

This paper is concerned with the origins and development of the concept of cyberterrorism. It seeks to excavate the story of the concept through an analysis of both popular/media renditions of the term and scholarly attempts to define the borders of same. The contention here is not that cyberterrorism cannot happen or will not happen, but that, contrary to popular perception, it has not happened yet.
