Description
Discretionary Access Control (DAC) is based on the premise that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. DAC allows the owner to determine who will have access to objects they control. An example of DAC includes user controlled file permissions. DAC models have the potential for the access controls to propagate without limit resulting in unauthorized access to said objects. When applications provide a discretionary access control mechanism, the application must be able to limit the propagation of those access rights. Rationale for non-applicability: This SRG applies to single-user applications. Therefore, access rights cannot propagate to other users.
