Question

An organization is trying to decide which type of access control is most appropriate for the network. The current access control approach is too complex and requires significant overhead. Management would like to simplify the access control and provide user with the ability to determine what permissions should be applied to files, document, and directories. The access control method that BEST satisfies these objectives is:

Options

  • ARule-based access control
  • BRole-based access control
  • CMandatory access control
  • DDiscretionary access control

Why each option

The organization aims to simplify access control and empower users to determine permissions for their files and directories. Discretionary access control (DAC) is the most suitable method as it allows resource owners to manage access.

ARule-based access control

Rule-based access control defines access based on a set of system-defined rules, which often adds complexity and does not inherently give individual users control over their own resource permissions.

BRole-based access control

Role-based access control (RBAC) assigns permissions to roles, and users inherit those permissions by being assigned to a role, which does not provide users with the direct ability to determine permissions on their specific files and directories.

CMandatory access control

Mandatory access control (MAC) strictly enforces system-wide access policies based on security labels and sensitivity levels, overriding user discretion, making it highly complex and directly contrary to empowering users to manage their own file permissions.

DDiscretionary access controlCorrect

Discretionary Access Control (DAC) grants the owner of an object (like a file or directory) the ability to define and modify permissions for other users. This directly aligns with the requirement to give users the 'ability to determine what permissions should be applied to files, documents, and directories' and can simplify centralized overhead by delegating control to resource owners.
