CHAPTER 7.4 INFORMATION SECURITY Because Holmes & Narver, Inc., was engaged in classified work for the U, S, Atomic Energy Commission, it was necessary not only to obtain clearances for its personnel and to establish physical security standards, but to establish, as well, an information control program to prevent unauthorized dissemination of classified information. When a prospective overseas employee was first processed through the Security Division, his final step in the processing procedure was a thorough 40 minute security lecture in a lecture room provided for that purpose. Everything expected of him in the control of information to which he would have access was carefully explained to him. He was familiarized with the Atomic Energy Act of 1946 and with the penalties for its violation, The personnel clearance procedure was explained to him, as were the responsibilities placed on a cleared employee. Finally, a question and answer period was held in order that all points could be clarified, (An outline of the lecture is presented as an ex- hibit at the end of this section.) When the overseas employee was finally cleared by AEC and put on a flight list for overseas, he was again called into the lecture room, where a 45-minute secondary security lecture was given him, reviewing information given him in the first security lecture and admonishing him to control his letter writing at the job and his participation in "scuttlebutt" sessions there. At the close of the second lecture, another question and answer period was held and a 16 mm sound film "Operation Sandstone” was shom, "Operation Sandstone" as shown in this instance, consisted of a depiction of a part of that operation which emphasized security aspects, which in general would apply to present and future operations, (An outline of this lecture is pre- sented as an exhibit at the end of this section.) To meet the different circumstances found in the Home Office the first lecture givenprospective Home Office employees was somewhat varied in emphasis from that given the overseas employee, More stress was laid on storage, handling, and transmittal of classified documents and on the control of special areas; and he (or she), like the over- seas employee, was thoroughly indoctrinated in the control of classified information, When the Home Office employees had received their AEC clearances, they were called to the lecture room in groups for a second security lecture, These groups were called at convenient times and in numbers calculated to cause the least interference with work. This lecture, for the most part, consisted of a thorough explanation of GM-37, "Storage, Handling and Transmittal of Classified Documents." For this, special charts were used, as well as the 16 mm Oak Ridge security sound film, At the conclusion of the lecture a question and answer period served to clarify any points in question. 7-18
