When a guide is being drafted for a new trade secret special control program, a security administrator, the program manager, and a patent attorney determine what information will be revealed through any type of media in the program. The four sections of the guide (1) list the types of information that must be designated as trade secrets and thus safeguarded from unauthorized disclosure, (2) prescribe marking requirements, (3) indicate physical security requirements, and (4) list administrative security requirements. Perimeter construction guidelines specify the minimum height and building material for the walls, as well as the material and locking methods for the doors. Access control guidelines describe the purpose of such control, the definition of unauthorized access, restrictions on photographs, when lock combinations should be changed, the retrieval of employee access instruments, and when to reprogram the access system. Eighteen items are listed as administrative requirements, ranging from the designation of security coordinators and monitors to a review of all photographic requests by the patents manager.
