§11103 Applicability to national security systems

Title 40 › Subtitle SUBTITLE III— - INFORMATION TECHNOLOGY MANAGEMENT › Chapter CHAPTER 111— - GENERAL › § 11103

Last updated Apr 6, 2026|Official source

Summary

Federal agencies must call a computer or communications system a national security system when it is used for intelligence, for secret code work tied to national security, for military command and control, as part of a weapon system, or when it is directly critical to military or intelligence missions. Systems used only for routine business tasks like payroll, finance, logistics, or personnel are not national security systems. Most of chapter 113 does not apply to national security systems. But sections 11313, 11315, and 11316 do apply. Agency heads must follow sections 11302 and 11312 as much as they can. They must also follow section 11303 as much as they can, and they must follow 11303(b)(5) except for subparagraph (B)(iv).
