Planning walkthrough

TEMPEST and SCIF planning checklist

Review selected project-record questions. An unanswered item remains not reviewed; it does not count toward progress or imply a gap. CTTA/AO determinations stay outside the self-check.

Self-checkable documentation records

Mark Yes, No, or Not applicable. No items appear as follow-up gaps; unknown/not reviewed remains visible until selected.

Existing shielded enclosure is identified and described.

Not reviewed until an answer is selected.

Existing supplemental shielding is identified and described.

Not reviewed until an answer is selected.

Perimeter wall construction is described.

Not reviewed until an answer is selected.

Ceiling and floor materials, thicknesses, and distances are recorded.

Not reviewed until an answer is selected.

Window quantities, sizes, and countermeasures are recorded.

Not reviewed until an answer is selected.

Signal lines and their exits are documented.

Not reviewed until an answer is selected.

Installed filters and isolators have make, model, and location recorded.

Not reviewed until an answer is selected.

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

Applicable adjacent occupants are shown.

Not reviewed until an answer is selected.

Authority-owned determinations

  • Whether TEMPEST countermeasures, including RF protection, are required.
  • CTTA facility-specific recommendations.
  • Required filtering or isolation for systems and penetrations.
  • Power and communications countermeasures.
  • Required dielectric breaks, grounding, or penetration treatment.
  • Whether RF protection is required at the inspectable-space boundary.

These six CTTA/AO items are not self-certified or included in progress.

0% of self-checkable items reviewed; all other items are not reviewed.

Worked use

Record existing paths and conditions before an authority review. Marking a record “No” makes it a follow-up item; it does not determine compliance.

Limitations

This is not an official checklist submission, compliance score, accreditation assessment, construction specification, or TEMPEST determination. Use current project CSA, AO, and CTTA direction.
