The document "Context-Based Access Control for Zero Trust" provides guidance on implementing context-based access control (CBAC) in Zero Trust architectures. It explains how traditional access controls, based on trust and static entitlements, are insufficient for modern security challenges. CBAC enhances security by making real-time, risk-based access decisions using dynamic signals like user behavior, device health, location, and network conditions. This approach aligns with Zero Trust principles, which continuously evaluate access requests and eliminate implicit trust.

CBAC adapts to evolving contexts and provides flexibility for human and non-human identities. It improves security by assessing contextual factors for every access request, making it a critical element for Zero Trust implementations. The document also compares CBAC with other access models, such as Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC), highlighting CBAC’s stronger alignment with Zero Trust due to its ability to consume dynamic signals and assess risks.

Additionally, the paper outlines a maturity model for CBAC, offers solutions for scaling and managing operational overhead, and explores how AI can enhance CBAC by speeding up decision-making and improving risk analysis. CBAC ultimately provides business benefits like improved security, operational efficiency, and compliance.
