You are reviewing access control models and want to implement a model that allows the owner of an object to grant privileges to other users. Which of the following meets this requirement?Group of answer choicesRole-Based Access Control (RBAC) modelDiscretionary Access Control (DAC) modelRule-based access control modelMandatory Access Control (MAC) model
Solution
The model that allows the owner of an object to grant privileges to other users is the Discretionary Access Control (DAC) model. In this model, the data owners have the discretion to grant access rights to other users or revoke their access rights. This is different from other models like Role-Based Access Control (RBAC) where access is granted based on the role of the user, or Mandatory Access Control (MAC) where access is granted based on predefined policies. Rule-based access control model, on the other hand, grants access based on a set of rules defined by a system administrator.
