Which option is considered not a goal of an access control mechanism?

A goal of access control mechanisms is to define and manage who can access resources and what actions they can perform on those resources. Ensuring that permissions are enforced is crucial because it maintains the integrity and confidentiality of the system by allowing only authorized users to perform specific actions. Similarly, enforcing the principle of least privilege ensures that users are granted only the minimal level of access necessary to perform their functions, thereby reducing the risk of unauthorized access or misuse of information.

Acceptable usage guidelines are another key concept linked to access control, as they outline how resources should be used, ensuring that users adhere to established policies that protect the organization's assets.

In contrast, ensuring accurate usage is not a primary goal of access control mechanisms. While accuracy in data handling and processing is important, the primary focus of access control is on managing user permissions and ensuring that access policies are correctly followed. Therefore, the function of access control does not directly relate to guaranteeing the accuracy of how users engage with data, but rather to ensuring proper authorization and access rights are in place.
