Following the September 11th terror attacks in New York City and Washington, D.C., policymakers in the United States began placing a stronger emphasis on cybersecurity and terror prevention. Due to the rapidly changing nature of cybersecurity, it was difficult to quickly address all the cybersecurity threats looming over the United States. Early efforts to improve cybersecurity included the establishment of the Department of Homeland Security to organize cyber threat data across various agencies. Several pieces of data-sharing legislation were circulating through Congress at this time, as well. Soon after, the U.S.A. Patriot Act became law. President Obama prioritized cybersecurity during his administration, and President Trump is prioritizing the issue, as well. This research paper finds the aforementioned policies implemented after the 9/11 attacks to be successfully detecting online communication between terrorist actors and protecting the cybersecurity interests of the United States.
