Subdomain 1.2: Define identity concepts
1.Which statement best describes identity as the primary security perimeter in a modern security approach?
- A.Access decisions rely primarily on verifying who or what is requesting access, rather than on the network location of the request
- B.Access decisions rely primarily on the physical location of the datacenter hosting the resource being requested
- C.Access decisions rely primarily on whether the request originates from inside the corporate firewall
- D.Access decisions rely primarily on the strength of the encryption algorithm used to transmit the request
Show answer & explanation
Correct answer: A — Access decisions rely primarily on verifying who or what is requesting access, rather than on the network location of the request
- A. Correct. As organizations move away from network-based perimeters, identity becomes the control point: access is granted based on verifying the requesting user, device, or workload rather than where the request originates.
- B. Incorrect. Datacenter location is an infrastructure detail and does not verify who or what is making the request, so it cannot serve as a security perimeter.
- C. Incorrect. Trusting requests simply because they come from inside a corporate network reflects the older network-perimeter model that identity-centric security replaces.
- D. Incorrect. Encryption strength protects data in transit but says nothing about whether the requesting identity should be trusted, so it does not define the perimeter.
