Solution
The mechanism in Role-Based Access Control (RBAC) that prevents privilege accumulation and enforces the principle of least privilege is Session Management Controls.
Here's a step-by-step explanation:
-
RBAC is a system that restricts system access to authorized users. It is used to control who has access to what within a system by assigning roles to users.
-
The principle of least privilege is a computer security concept in which a user is given the minimum levels of access necessary to complete his/her job functions.
-
Privilege accumulation is a situation where a user gathers more and more privileges over time, which can lead to a security risk if the user has more access rights than necessary.
-
Session management controls in RBAC help to prevent privilege accumulation and enforce the principle of least privilege. This is done by limiting the privileges of a user to the minimum necessary for the duration of their session.
-
When a user starts a session, they are assigned roles based on their needs for that session. Once the session is over, the roles are revoked, preventing the accumulation of privileges over time.
-
Therefore, through session management controls, RBAC ensures that users only have the access they need when they need it, thereby enforcing the principle of least privilege and preventing privilege accumulation.
