Starting with the Solaris 10 11/06 release, Solaris Trusted Extensions provides multilevel security for the Solaris OS. This feature enables you to control information in a flexible but highly secure manner. You can now enforce strict access controls to your data based on data sensitivity, not just data ownership.
An installation that accesses Solaris Trusted Extensions differs from a standard installation. For a list of these installation differences and further information about Solaris Trusted Extensions, see Installing or Upgrading the Solaris OS for Trusted Extensions in Solaris Trusted Extensions Installation and Configuration for Solaris 10 11/06 and Solaris 10 8/07 Releases.
