DISA Releases Initial Zero Trust Reference Architecture ChakisAtelier/iStock.com email May 14, 2021 12:54 PM ET The architecture will help the military “maintain information superiority on the digital battlefield,” according to the press release. The Defense Information Systems Agency finished the initial version of its zero-trust reference architecture for cybersecurity, according to a May 13 press release. Zero trust is a cybersecurity paradigm that calls for a data-focused, rather than network and perimeter-based, approach—and though the concept has been gaining steam in government, an executive order released May 12 specifically directs agencies to implement it. Then-DISA Director Vice Adm. Nancy Norton originally announced in July that DISA would release a zero-trust reference architecture for the Defense Department.
