Which of the following is the MOST effective type of access control?
A. Centralized
B. Role-based
C. Decentralized
D. Discretionary
Explanation:
Role-based access control allows users to be grouped into job-related categories, which significantly cases the required administrative overhead. Discretionary access control would require a greater degree of administrative overhead. Decentralized access control generally requires a greater number of staff to administer, while centralized access control is an incomplete answer.
