The requirement for computer terminals processing classified material is outlined in OPNAVINST C5510.93. This instruction specifically addresses the safeguarding of classified information within the U.S. Navy, providing the necessary guidelines and standards for the protection of classified data. It covers various aspects of information security, including the handling of equipment and technologies that interact with classified materials.
