One thing you guys are missing about the security issue is that all
devices must be controlled under it also.

Every terminal/tape drive/printer/fax/whatever must also be classified
as to its security clearance.

This security is in addition to any other security that is in place.

If a printer is not "top secret" cleared then you cannot print a top
secret document to it even if you have the clearance.  And you cannot
display it on a terminal that does not have the proper clearance.

About all  OS400 can do is limit security officer signon to specific
devices.
