The escalation of attacks on computer systems, driven by both criminal motives and political agendas, poses a growing threat in the United States and globally. Concurrently, foreign terrorist organizations are harnessing information technology to further their objectives. The convergence of these phenomena has prompted widespread concern among security experts from government and private sectors, who emphasize the looming specter of cyber-terrorism. Despite this, a precise definition of cyber-terrorism remains elusive within United States law and among cybersecurity scholars, hampering effective legislative and strategic responses. This paper endeavors to fill this conceptual gap by presenting a comprehensive lexicon of cyber-related malicious activities and advocating for a unified understanding of cyber-terrorism. Such a definition is essential for integrating cyber-terrorism into existing counter-terror legislation and empowering government agencies to combat this emergent threat. Through an exhaustive analysis of proposed definitions by security experts and governmental organizations, a new definition is proposed-one that strikes a delicate balance, encompassing the unique ramifications of cyber-terrorism while excluding less significant cyber incidents. Moreover, recent cyber attacks underscore the pressing need for proactive measures, as the complexity and frequency of politically motivated cyber assaults continue to escalate, albeit without reaching a catastrophic "cyber 9/11" scenario thus far. Critically assessing current legal frameworks governing cyber-crimes and terrorism, the paper identifies gaps, particularly in the realm of prevention. Consequently, it advocates for the incorporation of the proposed definition of cyber-terrorism into key anti-terrorism laws, thereby bolstering efforts to preempt and mitigate this evolving threat landscape
