What are the differences between access control models?

There are several access control models, including Discretionary Access Control (DAC), Mandatory Access Control (MAC), Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC). Each has its own strengths and weaknesses.

Can you explain how Role-Based Access Control (RBAC) works?

Sure! RBAC assigns permissions to roles rather than individual users. Users are then assigned to roles, which simplifies management and enhances security.

What are the advantages of using Mandatory Access Control (MAC)?

MAC provides a high level of security by enforcing strict policies that cannot be altered by users. It's often used in environments that require strong data protection.

How does Attribute-Based Access Control (ABAC) differ from RBAC?

ABAC uses attributes (like user, resource, and environment attributes) to make access decisions, allowing for more granular control compared to RBAC, which is role-centric.
