Implementing a business-driven enterprise security architecture like the SABSA model is a systematic process that moves from abstract business goals to concrete technical controls.

Outlines the security services, such as identity management, data encryption, and access control. ZTA is becoming foundational

Zero Trust Architecture implements a model of "never trust, always verify," "assume breach," and "least privileged access," continuously verifying the identity and permissions of all entities before granting access.
