![]() This form of MAC is considered the most flexible implementation, but it also is the most complex to deploy across the enterprise. ![]() This type of access control is what is employed in SELinux. Typical basic access control elements include users, roles and types and together they form a security context which is the basis for the security labels. The access control check will compare the assigned user's credentials to that of the resource or object they are attempting to access.Ī security context is associated with resources and is used to determine assess. ![]() Users attempting to access a resource will result in the operating system performing an access control check. Identifier labels are applied to resources and users are assigned a similar access identifier. This type of MAC requires that the file system has built-in support for security labels.Īccess controls are typically implemented through the use of label identifiers for every file system object. Common MAC implementations Security label access controlĪ fine-grained form of mandatory access control is to apply security labels to individual resources, including processes, and the access control decisions are against a particular resource and a given user attempting to gain access. Rules and policies are defined that associate subjects and object permissions and access controls. Subjects are the entities requesting access and objects are the resources that subjects are trying to access. Access determinations are based on designed access control polices and are not based on local resource owner determinations.Īccess is typically granted by defining sets of subjects and sets of objects. Mandatory access control is a non-discretionary access control system because the rules and polices that determine access is determined by a security control authority and not distributed to local users. Controlling access to local computer system resources with kernel-level capabilities.
