ABSTRACT:
A computer workstation having a window output display for potential use in security-sensitive environments provides multilevel security by physical isolation of processes in predefined security levels, each process or like-classified group of processes is displayed only through a suitably labeled window, access to the window requiring access through a previously security qualified physical signal path. The invention does not compromise security by mixing a software-based security environment with other untested software. All security is hardware-based.
