What is the DoD Information Security Program document number?

The correct choice identifies the DoD Information Security Program document as DoDI 5200.01. This document is a critical component of the Department of Defense’s overarching strategy for information security, providing comprehensive guidelines and protocols to safeguard sensitive information within the DoD.

DoDI 5200.01 outlines the policies and procedures necessary for protecting information systems and their data from unauthorized access and threats, thus ensuring confidentiality, integrity, and availability. This instruction serves as a foundational reference for compliance with federal laws, regulations, and policies concerning information security, streamlining how personnel manage sensitive information across various platforms in the defense environment.

The other choices refer to different documents or concepts that are not directly related to the DoD Information Security Program. For example, DoD 8500.01 pertains to information assurance and risk management framework, while the reference to ARPANET is associated with early networking rather than current information security practices. Lastly, DoDI 1000.01 does not address the information security program specifically, focusing instead on other administrative issues within the DoD.
