Letting Users Select Single- or Multilevel Sessions

When you first log into a Trusted Solaris session, you specify whether you will be operating at a single sensitivity label or at multiple sensitivity labels (if you are permitted to). You then set your session clearance or session sensitivity label, that is, the security level at which you intend to operate.

In a single-level session, you can access only those objects at or dominated by your session sensitivity label.

In a multilevel session, you can access information at different sensitivity levels, as long as they are at or lower than your session clearance. In the Trusted Solaris environment, you can specify different sensitivity labels for different workspaces.
