An organization wants to implement an access control system based on its data classification policy that includes the following data types:
Confidential
Restricted
Internal
Public
The access control system should support SSO federation to map users into groups. Each group should only access systems that process and store data at the classification assigned to the group. Which of the following should the organization implement to enforce its requirements with minimal impact to systems and resources?
Correct Answer: A
Attribute-Based Access Control (ABAC) with a tagging strategy allows flexible and granular access control based on resource classification and user attributes. This minimizes system impact and ensures compliance with data classification policies. This aligns with CASP+ objective 3.4, focusing on advanced access control mechanisms.
