Visible Features of Trusted Extensions

After you have successfully completed the login process, as explained in Chapter 2, Logging In to Trusted Extensions, you can work within Trusted Extensions. Your work is subject to security restrictions. Restrictions that are specific to Trusted Extensions include the label range of the system, your clearance, and your choice of a single-level or multilevel session. As the following figure illustrates, several features distinguish a system that is configured with Trusted Extensions from an Oracle Solaris system.
