CSA Exam CCZT Topic 2 Question 29 Discussion

Policy is the element of ZT that focuses on the governance rules that define the ''who, what, when, how, and why'' aspects of accessing target resources. Policy is the core component of a ZTA that determines the access decisions and controls for each request based on various attributes and factors, such as user identity, device posture, network location, resource sensitivity, and environmental context. Policy is also the element that enables the ZT principles of ''never trust, always verify'' and ''scrutinize explicitly'' by enforcing granular, dynamic, and data-driven rules for each access request.
