ABSTRACT
Zero Trust Security has emerged as a key security approach in the world today. The US Cyber and Infrastructure Agency (CISA) drafted a Zero Trust Maturity Model in June 2021 to assist agencies with the development of their zero trust strategies and implementation plans. The maturity model has five pillars and three horizontal capabilities with three levels of maturity. This presentation will provide an overview of the maturity model and relate the importance of capabilities to a government/military context.
