Single-level Versus Multilevel Sessions

In a multilevel session, you can operate at different labels. The range in which you operate is bounded at the upper end by the session clearance you specify and at the lower end by the minimum label assigned to you by your administrator.

In a single-level session, you specify a session label at which you operate for the entire session. In a single-level session, you can access and write to files at that label only. You cannot change the label of workspaces in the session. Note that you can assume a role within a single-level session and then operate at any label available to that role.
