In the context of access control, what does compartmentalization provide?

Compartmentalization in access control refers to the strategy of dividing resources or systems into separate sections, each with its own specific access controls and requirements. This method ensures that access rights are minimized and only granted to individuals who need them for their specific roles or tasks. By requiring multiple controls for access, compartmentalization enhances security by limiting the exposure of sensitive information or critical systems.

When access is compartmentalized, if an individual gains unauthorized access to one compartment, this does not automatically grant them access to other compartments. This layered approach significantly reduces the risk of a security breach, thereby enhancing the overall security posture of an organization. Compartmentalization aligns closely with the principle of least privilege, ensuring that users only have access to the information and systems necessary for their job functions.
