What is a key benefit of ZTNA in terms of access control?

The benefit of ZTNA (Zero Trust Network Access) that stands out is its ability to enforce granular access control policies. This approach is fundamental to the zero-trust security model, which assumes that no user or device should be trusted by default, regardless of whether they are inside or outside the network perimeter.

With granular access control, ZTNA allows organizations to define specific access policies based on various factors such as user role, device health, location, and application sensitivity. This level of specificity ensures that users are granted access only to the resources they need to perform their job functions, significantly reducing the risk of unauthorized access and data breaches. By implementing such precise controls, organizations can also respond more effectively to security incidents by quickly adjusting access permissions as needed.

In comparison, options suggesting unlimited access, the elimination of user credentials, or simplification of the authentication process do not reflect the core principles of ZTNA. Unlimited access contradicts the zero-trust model by undermining its primary objective of limiting access. Eliminating credentials would pose significant security risks, as verification of identity is crucial in any access control framework. Simplifying authentication might improve user experience but does not inherently address the fundamental purpose of ZTNA—enhancing security through controlled access.
