Which access control model originates from the military and uses security labels?
- access control list
- discretionary access control
- mandatory access control
- role-based access control
| Explanation & Hint:
The access control model that originates from the military and uses security labels is Mandatory Access Control (MAC). In MAC systems, access decisions are based on security labels, which include classifications (such as top secret, secret, confidential) and categories (that represent sensitivity to certain subjects, like nuclear, military, financial). The system enforces access controls based on these labels, and users cannot change the labels or access controls at their discretion. This model is known for its strictness and is commonly used in environments that require a high level of security. |
