Answer: An attribute-based access control (ABAC) system that evaluates policies using attributes of users, data, and the environment.
An attribute-based access control (ABAC) system is the most suitable model for a dynamic access control system that adjusts permissions based on the sensitivity of the data being accessed while ensuring data protection. ABAC evaluates policies based on attributes of users, data, and the environment, allowing for a more granular and flexible approach to access control. This model enables dynamic adjustments to permissions as the sensitivity of the data changes, ensuring that only authorized users can access the data under the current conditions. Unlike RBAC, which may lack the flexibility to adapt to changes in data sensitivity, or MAC, which may be too rigid, ABAC provides the necessary adaptability and precision. DAC, while flexible, relies on manual adjustments which can be inefficient and prone to errors in large environments.

For a system designed to dynamically adjust access permissions based on the sensitivity of the data being accessed, which model offers the greatest flexibility while ensuring data protection?
A
A mandatory access control (MAC) system that classifies all data and user roles with sensitivity levels, enforcing strict access rules.
B
A role-based access control (RBAC) system with static permissions assigned to user roles.
C
An attribute-based access control (ABAC) system that evaluates policies using attributes of users, data, and the environment.
D
A discretionary access control (DAC) system where data owners manually adjust permissions based on sensitivity.
