ICD 705 is the Intelligence Community Directive that sets the physical and technical security standards for Sensitive Compartmented Information Facilities (SCIFs), covering construction, TEMPEST, acoustic protection, access control, and more. Meeting ICD 705 is what allows a facility to be accredited to process classified information — and because the accrediting official has discretion in how requirements are applied, experienced guidance helps you meet the standard without over-building beyond what’s actually required.
