Which OPNAV instruction contains procedures for securing AIS material?

The correct answer is that OPNAVINST 5239.1 contains the procedures for securing Automated Information Systems (AIS) material. This instruction specifically addresses the security measures and protocols necessary for protecting AIS resources and associated information. It emphasizes the importance of safeguarding sensitive data and ensures compliance with security regulations within the Navy's operational environment.

Understanding the context of AIS material is crucial; these systems often handle classified or sensitive information, requiring robust security protocols to mitigate risks. By following the guidelines laid out in OPNAVINST 5239.1, personnel can ensure the integrity, confidentiality, and availability of the information processed by these systems.

The other options pertain to different aspects of Navy operations and security. While they may cover related topics such as information assurance and administrative procedures, they do not specifically focus on the securing of AIS material like OPNAVINST 5239.1 does. This makes understanding the appropriate regulations essential for those working with or overseeing AIS within the Navy.
