What are the differences between access control methods?

There are several access control methods, including discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC). Each has its own principles and use cases.

Can you explain discretionary access control?

Discretionary access control (DAC) allows the owner of a resource to make decisions on who can access it. The owner can grant or revoke access rights.

What about mandatory access control?

Mandatory access control (MAC) enforces access policies based on regulations set by a central authority. Users cannot change access permissions.

And role-based access control?

Role-based access control (RBAC) assigns permissions based on user roles within an organization, simplifying management of user rights.

Which method is the most secure?

Mandatory access control (MAC) is generally considered the most secure, as it restricts access based on strict policies that cannot be altered by users.
