Zero Trust is a security model that eliminates implicit trust and continuously validates every stage of access in an organization. It aims to reduce cybersecurity threats, such as ransomware, by assigning the least required access needed to perform specific tasks. Authentication and authorization are discrete functions that cybersecurity teams perform before allowing access to networks and systems. The model has three main tenets: risk awareness, least privileged access, and continuous access verification. The five pillars of Zero Trust are identity, device, network, application workload, and data. The strategy lays out four main goals: zero trust culture adoption, DoD information systems secured and defended, technology acceleration, and zero trust enablement. An example of a Zero Trust policy is allowing granular access only to the data and functionality of an application that a specific entity requires.
