Information Security

The Information and Personnel Security Branch develops and oversees implementation of Department of the Navy (DON) policy for the designation, marking, protection, and dissemination of classified and controlled unclassified information. This combined guidance is commonly referred to as the DON Information Security Program (ISP). The DON ISP harmonizes and aligns processes among collateral, Sensitive Compartmented Information (SCI), Special Access Program (SAP), and Controlled Unclassified Information (CUI) to the maximum extent possible to promote information sharing, facilitate judicious use of scarce resources, simplify management implementation, and oversight. The Branch also maintains the DON’s authoritative list of all current security classification guides and Original Classification Authorities (OCAs). We also provide security review service for the Secretariat, Commandant of the Marine Corps and Chief of Naval Operations on all materials provided to the Congress.

The Information and Personnel Security Branch is the DON ISP requirements advocate at Department of Defense and interagency policy forums.



What precautions should I take before posting government information on the internet?
Before you post any type of government information, including names of government personnel with their job affiliations, on a publicly accessible web site, you must have the information reviewed by your command for public release. This review also includes a pre-publication security review to prevent classified or "for official use only" information from being inadvertently released to the public.
Do I have to submit all documents originating in the DC area for pre-publication review by N09N2 and DoD?
SECNAVINST 5510.36, exhibit 8B, lists the types of information that must be forwarded to CNO(N09N2) for review by the Assistant Secretary of Defense (Public Affairs) prior to publication. This includes information which "Originates or is proposed for public release in the Washington DC area" (paragraph 1.a). The long-standing interpretation of this requirement is that it is directed to and applies to Senior Level personnel (i.e., Flag Officers and SES) dealing with political policy and military "hot-button" issues that have the potential to be of news-worthy interest, such as the TV evening news or the newspaper. Follow the guidelines of Exhibit 8B and coordinate with your public affairs office to complete pre-publication security reviews at your command to the maximum extent possible.
If I am processing an unclassified e-mail on a classified system, do I have to mark it "UNCLASSIFIED"?
Yes. All documents, to include attachments, drafted and transmitted on a classified network need to be appropriately marked per SECNAV M-5510.36, Chapter 6.
I received an e-mail on a classified system that is not marked. How do I handle the document and am I required to mark the document at the same level of the classified network?
Request the sender to properly mark the document. Safeguard it at the highest classification level of the system until you receive the proper marking of the document from the sender. The basic principle for this policy is addressed in SECNAV M-5510.36, Chapters 4, 6, and 7.
