ABSTRACT:
The system of the present invention provides physical access control for storage media in stand-alone workstations which are processing classified or unclassified sensitive information. The system protects the workstation media from theft, tampering and from observation of the monitor by passers-by. The system, when invoked, presents an alarmed-state security screen, allows only passwords to be entered from the keyboard, and protects writable media from access or removal. An alarm sounds if (a) any drives (both internal and external) containing writable media are opened or removed, (b) the program is interrupted, (c) too many invalid password characters are entered, or (d) the power is interrupted.
