Which type of access control is managed consistently by administrators for all data?

The type of access control that is managed consistently by administrators for all data is Mandatory (Non-Discretionary) Access Control. This approach is characterized by its structured and regulated control over who can access specific information, based on a set of rules defined by the organization.

In Mandatory Access Control (MAC), users are granted access to data based on their security clearance level, and this level is determined by the system rather than the user themselves. The rules that govern access are predefined and enforced by the system, ensuring that no individual has the discretion to change permissions. This results in a uniform application of policies across all data, which helps maintain the integrity and security of sensitive information.

The benefits of this approach include a higher level of security because it limits user control over their access rights. It is particularly useful in environments where data sensitivity is critical, such as government or military settings, where strict compliance to access controls is necessary to safeguard information.

In contrast, the other access control models offer varying levels of user discretion and flexibility, which may lead to inconsistent application of permissions across different data sets.
