What approach best reduces security administration efforts?

• A. Access control lists (ACLs)
• B. Discretionary access controls (DACs)
• C. Mandatory access controls (MACs)
• D. Role-based access controls (RBACs)

Answer: (D)

Role-based access controls (RBAC) is the approach that significantly reduces security administration efforts because it simplifies the management of user permissions by assigning access rights based on predefined roles within the organization. Instead of managing individual permissions for each user, which can be both time-consuming and prone to errors, RBAC allows for easier management since users are grouped based on their roles, such as manager, finance, or IT staff. This role-centric model streamlines processes, especially in larger organizations where managing multiple user accounts and permissions can become unwieldy. By creating roles that encapsulate a set of permissions, security personnel can efficiently assign, modify, or revoke access as employees transition between roles or leave the organization. Other access control models like access control lists, discretionary access controls, and mandatory access controls may provide security benefits but don't offer the same level of efficiency in administration. ACLs require individual management of each access point, DACs empower users to make access decisions potentially leading to inconsistencies, and MACs impose strict classifications that can complicate administrative tasks rather than simplify them. This differentiation emphasizes why RBAC is the preferred method for minimizing unnecessary security administration efforts while maintaining robust access control.
