what is cui specified?

CUI Specified is a subset of Controlled Unclassified Information (CUI) that must be protected using explicit handling and safeguarding rules laid out in particular laws, regulations, or government‑wide policies. It is not classified, but it is more tightly controlled than standard “CUI Basic” because its protection requirements are spelled out in those authorities.

What CUI Specified Means

• CUI Specified is CUI where the authorizing law or regulation includes specific handling, safeguarding, or dissemination controls that differ from the default CUI rules.

• If the authority says “you must protect this information and here is exactly how,” that information falls into the CUI Specified category.

• This category often appears in higher‑risk or high‑priority government and defense programs, where misuse could create serious national security or privacy issues.

How It Differs From CUI Basic

• CUI Basic uses a common, baseline set of controls (for example, the general requirements aligned with NIST SP 800‑171) without additional, special procedures.

• CUI Specified adds extra or different requirements mandated directly by law or regulation, so organizations must follow those instructions in addition to baseline CUI protections.

• Because of that, CUI Specified is usually more complex to manage, with stricter access, marking, and dissemination rules than CUI Basic.

Typical Examples

• Information controlled under International Traffic in Arms Regulations (ITAR), covering certain defense items, technical data, or related services.

• Naval Nuclear Propulsion Information (NNPI), which concerns design, operation, and maintenance of U.S. Navy nuclear propulsion plants and facilities.

• Certain “controlled technical information” with military or space applications, where specific federal codes prescribe how it must be marked and protected.

Why It Matters In Practice

• Organizations handling CUI Specified must implement the precise controls in the governing authority: specialized markings, stricter access limitations, secure transmission, and defined decontrol rules.

• This often means stronger encryption, tighter role‑based access, more detailed incident reporting, and more frequent security assessments than for basic CUI.

• Failing to follow the specific rules for a CUI Specified category can create compliance violations even if general CUI safeguards are in place.
