De-elevation of Super User Access
Does this mean that Super User access would be provided and removed based on specific need? If so, I think this is the only way to adhere to the "least privilege" principle completely.

Gee so it's just like a mainframe running RACF in 1984
Finally we are back to the days when the system has real security!

Multilevel security
 

Multilevel security should be about multi-layer security. When individuals need to go to next level they get permission otherwise they could not proceed. This is one of the good approach when it comes best practices on secure network and system design.

Re: De-elevation of Super User Access
Main idea should be the fact that there is no super user. You get permission based on the need you have and that is given temporary.

I hear you. At the same time there was always security vulnerabilities as you know.

I like the idea of having a dump terminal for the users and locking down everting else in the back end, however security is about balance of CIA: Confidentiality, Integrity and Availability

Re: Gee so it's just like a mainframe running RACF in 1984
yes, we had a guy that could look over your shoulder at your 3270 terminal , on the closed network, running proprietary protocols, encrypted with simple routines.  That guy could read your screen.

Other than that, the no wireless, no terminal that was not explicitly defined to the system approach worked quite well.

Systems of systems
I wonder how they would be securing systems of systems while they are having hard time to secure a single system. Noting is ever be perfect when it comes to security, all we are doing minimizing the risk.

Re: De-elevation of Super User Access
Sorry if my first post didn't phrase as such but that was the point behind my statement. Permanent elevation is quite common and not a good security practice.
