Which instruction governs the safeguarding of classified material?

The safeguarding of classified material is primarily governed by SECNAV M5510.36 (series). This instruction outlines the procedures and policies necessary for protecting classified information within the Department of the Navy, providing comprehensive guidance on the handling, storage, transmission, and destruction of classified materials.

By adhering to the stipulations set forth in SECNAV M5510.36, personnel are equipped with the knowledge and procedures needed to maintain the integrity and security of sensitive information, thereby minimizing the risk of unauthorized access or disclosure. The instruction is vital in establishing the standards and responsibilities of personnel in managing classified material effectively.

The other choices represent different instructions that cover various aspects of security and management within the Navy but do not specifically focus on the safeguarding of classified materials. Understanding this distinction is important for ensuring compliance with the correct guidelines related to classified information.
