Which access control model allows users to manage permissions for various resources in a flexible manner?

Discretionary Access Control (DAC) is designed to give users the ability to manage permissions for various resources in a flexible manner. In a DAC model, the owner of a resource has the authority to make decisions about who can access their resource and what permissions they have. This model enables individuals to grant access to other users at their discretion, which allows for a dynamic and adaptable approach to permissions management.

DAC is particularly valuable in environments where collaboration is essential, as it empowers users to share information and resources without requiring intervention from an administrative authority for every access request. It contrasts with more restrictive models, which might limit how permissions can be assigned or modified. By allowing users the freedom to control access, DAC supports a more fluid and situationally adaptive security framework, enabling tailored access based on the specific needs and relationships between users and resources.
