The Trusted Extensions software provides a set of policies and services to extend the security features of the Oracle Solaris operating system. These extensions provide access control that is based on label relationships.
Labels control access to data and maintain the classification of data. The labels are attributes that are interpreted by the system security policy. The system security policy is the set of rules that is enforced by system software to protect information that is being processed on the system. The term security policy can refer to the policy itself or to the implementation of the policy. For more information, see Trusted Extensions Security Policy.
This section includes overview information about label types, ranges, components, and relationships.
