What instruction pertains to electronic data security procedures?

The correct choice focuses on OPNAVINST 5239.1, which specifically addresses electronic data security procedures. This instruction outlines the guidelines and standards for safeguarding sensitive data and maintaining data integrity within the Navy's operations. It covers aspects such as computer security measures, access control, system authentication, and the proper handling of information technology resources.

Understanding the context of this instruction is critical for fire controlmen, as they often work with sensitive electronic data related to weapon systems and platforms. Being familiar with the procedures and policies outlined in OPNAVINST 5239.1 helps ensure that data is adequately protected against unauthorized access, loss, or destruction, which is vital for operational security and mission success.

Other options, while relevant to various administrative and personnel regulations in the Navy, do not specifically relate to electronic data security procedures. For instance, BUPERSINST 1430.16 deals with enlisted advancement policy, SECNAVINST 5510.36 covers security and safeguarding of classified information, and NAVPERS 1070/600 is a form used for the record of enlisted service with no focus on electronic data security.
