On Nov. 22, the U.S. Department of Defense released their Zero Trust Strategy, a new approach to countering cyberattacks. The new framework employs a “‘never trust, always verify’” mindset, deviating from the Defense Department’s previously used perimeter defense model. The strategy is prompted by the “rapid growth” of offensive cyber threats and aims to fully implement the department-wide model by fiscal year 2027.
As our lives become increasingly dependent upon computer systems and cyber technologies grow ever more sophisticated, the internet has emerged as the new battleground of the 21st century. From criminals' stealing credit card and social security number information to foreign governments' hacking into American companies’ information systems, cyber attacks can take on myriad forms, prompting the government to formulate new measures to protect online security. Since cyberwarfare knows no territorial bounds, ensuring cybersecurity will also require international cooperation and an updated understanding of jus ad bellum, as it applies to cyber attacks.
