If it does not use mandatory access control, this is not a finding. In computer security, mandatory access control ( MAC) refers to a type of access control by which the operating system or database constrains the ability of a subject or initiator to access or generally perform some sort of operation on an object or target. Network Device Management Security Requirements GuideĬheck the network device to determine if organization-defined mandatory access control policies are enforced over all subjects and objects. An example of where mandatory access control may be needed is to prevent administrators from tampering with audit objects. Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. ![]() The mandatory access control policies are defined uniquely for each network device, so they cannot be specified in the requirement. In computer systems security, role-based access control (RBAC) or role-based security is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control (DAC). The reference monitor enforces (mediates) access relationships between all subjects and objects based on privilege and need to know. This class of mandatory access control policies also constrains what actions subjects can take with respect to the propagation of access control privileges that is, a subject with a privilege cannot pass that privilege to other subjects.Įnforcement of mandatory access control is typically provided via an implementation that meets the reference monitor concept. Source(s): NIST SP 800-53 Rev.Mandatory access control policies constrain what actions subjects can take with information obtained from data objects for which they have already been granted access, thus preventing the subjects from passing the information to unauthorized subjects and objects. Mandatory Access Control, or MAC for short, refers to a cybersecurity system that looks to allow or deny access to private and protected information in an organization.

Source(s): CNSSI 4009-2015 A means of restricting access to system resources based on the sensitivity (as represented by a label) of the information contained in the system resource and the formal authorization (i.e., clearance) of users to access information of such sensitivity. eral additional kernel mandatory access controls, includ ing controls for the.

Organization-defined subjects may explicitly be granted organization-defined privileges (i.e., they are trusted subjects) such that they are not limited by some or all of the above constraints. A subject that has been granted access to information is constrained from doing any of the following: (i) passing the information to unauthorized subjects or objects (ii) granting its privileges to other subjects (iii) changing one or more security attributes on subjects, objects, the information system, or system components (iv) choosing the security attributes to be associated with newly-created or modified objects or (v) changing the rules governing access control. ![]() An access control policy that is uniformly enforced across all subjects and objects within the boundary of an information system.
