Assertion (A): The Zero Trust security model assumes that no network traffic is inherently trustworthy.
Reason (R): Zero Trust requires continuous verification of all users and devices regardless of their location.

Correct option is A

The Zero Trust security model indeed assumes that no network traffic, whether from external or internal sources, is inherently trustworthy. It also requires continuous verification of all users and devices, regardless of their location, which is the essence of Zero Trust security. The reason correctly explains the assertion.
Important Key Points:
1. Zero Trust Security Model: Zero Trust is a security model that operates on the principle of "never trust, always verify." It does not trust any network traffic by default, even if it originates from within the network.
2. Continuous Verification: The core of the Zero Trust model is continuous verification, meaning that user and device identities, as well as the security of their access, are always assessed before granting access to network resources.
3. Assumption of Untrustworthy Traffic: By assuming all traffic is untrusted, Zero Trust minimizes the potential for data breaches and unauthorized access, making it crucial for modern network security.
