TEMPEST and SCIF planning checklist

Review selected TEMPEST and ICD 705 planning details, record visible gaps, and keep the items that require AO or CTTA determination separate from your self-check progress.

AO and CTTA determination required

This is a documentation walkthrough, not a compliance score. Review selected public checklist items here, then use the official forms and your AO and CTTA instructions for the real project determination.

Self-check progress

0 of 17 self-checkable items reviewed

0% reviewed · 6 items require CTTA determination

Follow-up gaps

Items you mark No will appear here. A No answer is a follow-up gap, not a compliance verdict.

Shielded enclosure

Any existing shielded enclosure is identified and described in the project record.

Not reviewed

Any existing supplemental shielding is identified and described in the project record.

Not reviewed

Perimeter wall construction is described in the project record.

Not reviewed

True and false ceiling and floor materials, thicknesses, and distances are recorded.

Not reviewed

Window quantities, sizes, and any existing countermeasures are recorded.

Not reviewed

Whether TEMPEST countermeasures, including RF protection, are required is determined for this facility.

CTTA determination required.
AO/CTTA determination

The CTTA's facility-specific recommendations are documented for the CSA and Accrediting Official.

CTTA determination required.
AO/CTTA determination

Power, signal, and telephone filters

Signal lines and distribution systems within the SCIF, including telephone, alarm, fiber, coaxial, and copper paths and their exits where applicable, are documented.

Not reviewed

Installed filters and isolators are documented with their make, model, and location.

Not reviewed

Exiting power-line paths, sources, materials, counts, and voltages are documented.

Not reviewed

Facility telecommunications systems are described in the project record.

Not reviewed

Required filtering, isolation, or other TEMPEST countermeasures are determined by the CTTA for the facility's systems and penetrations.

CTTA determination required.
AO/CTTA determination

Pipe and duct penetrations

HVAC, pipe, sprinkler, and other perimeter penetrations are mapped in the project record.

Not reviewed

Penetration paths, connections, composition, size, and accessibility are documented.

Not reviewed

Duct penetration quantities, sizes, protective measures, and inspection access are documented.

Not reviewed

Existing grounding mitigations, waveguides, and non-conductive sections are documented.

Not reviewed

Any required dielectric breaks, grounding, or other penetration treatments are determined for this facility.

CTTA determination required.
AO/CTTA determination

Inspectable space

Controlled-area status is recorded; if the SCIF is not in a controlled area, distances from its perimeter to the closest inspectable-space boundary are recorded.

Not reviewed

Foreign-controlled or foreign-occupied areas within 100 meters that are not readily accessible by SCIF personnel are shown on the external map.

Not reviewed

Internal plans show the SCIF, distribution lines, filters, conductors, and penetrations.

Not reviewed

If the SCIF is in a multi-story building not entirely controlled by the U.S. government, occupants above and below are shown; any non-government organizations across shared walls are also shown.

Not reviewed

Whether RF protection is required at the inspectable-space boundary is determined for this facility.

How this walkthrough works

Answer the self-checkable documentation questions with yes, no, or not applicable. The progress readout measures only whether you reviewed those items. Items reserved for the Accrediting Official or Certified TEMPEST Technical Authority stay outside the percentage and cannot be answered here.

What this does not score

This checklist does not determine compliance, accreditation readiness, required countermeasures, shielding performance, the classified threat environment, inspection results, waivers, or whether any documented condition is acceptable for your facility.

Important

This selected planning walkthrough is not a compliance score, accreditation assessment, official checklist submission, construction specification, or determination of required TEMPEST countermeasures. Use the latest applicable source documents and work with your Cognizant Security Authority, Accrediting Official, and Certified TEMPEST Technical Authority for project-specific requirements and acceptance.

Questions to verify

Frequently asked questions

Is the completion percentage a compliance score?

No. It measures how many self-checkable items you reviewed. It does not measure compliance, readiness, or the likelihood of accreditation. The AO and CTTA make the project determinations that matter.

Does this replace the official ODNI checklists?

No. Use the current documents and the instructions from your Cognizant Security Authority, AO, and CTTA. This walkthrough covers a selected planning subset and does not collect the facility details or attachments required by the official forms.

Why can I not answer the CTTA items?

Those items depend on the threat, equipment, location, and authority review. Presenting them as self-certifiable would turn a planning walkthrough into a false compliance claim.

Longlead shows which public projects may call for specialist shielding and secure-facility scope while your team can still prepare: on major federal projects, typically 9–18 months before the GC buys out your scope.
