CNSSAM tempest /1-13 17 January 2014 UNCLASSIFIED//FOR OFFICIAL USE ONLY CNSSAM tempest /01-13 CNSS Secretariat (IE32) National Security Agency * 9800 Savage Road * Suite 6716 * Ft Meade MD 20755-6716 UNCLASSIFIED//FOR OFFICIAL USE ONLY (U) FOREWORD 1. (U) Committee on National Security Systems Advisory Memorandum ( CNSSAM ) tempest /01-13, RED/BLACK Installation Guidance , provides criteria for the Installation of electronic equipment, cabling, and facility support for the processing of secure information.

2 This publication supersedes nstissam tempest / 2-95 and the tempest /2-95 Addendum of February 2000. 2. (U) tempest security is a function of the tempest characteristics of the processing equipment, the way the equipment is installed, the electromagnetic and physical characteristics of the facility, and the geographical environment of the facility location. 3. (U) The Guidance identified herein will be considered by a Certified tempest Technical Authority (CTTA) as part of the potential solution for facilities, system, and equipment that have been identified as requiring tempest countermeasures. Only those specific criteria identified by the CTTA will be implemented. When this document is implemented by direction or instruction, Government Agencies and Departments should contact their CTTA to obtain the applicable Installation criteria.

3 When implemented by contract, Government contractors should contact their appropriate government Contracting Office Technical Representative (COTR) for the applicable CTTA requirements. 4. (U) Committee on National Security Systems (CNSS) Representatives may obtain additional copies of this policy from the address below. Government contractors should contact their appropriate government Contracting Officer regarding further distribution and dissemination of this document. FOR THE NATIONAL MANAGER /s/ DEBORA A.

(U) Scope (U) This document defines the Guidance for the design of facilities and the Installation of equipment and systems that receive, transmit, route, switch, manipulate, graph, store, archive, calculate, generate, print, scan, or in any other manner process or transfer National Security Information (NSI).

9 This Guidance is part of the potential solution for facilities, systems and equipment identified as requiring tempest countermeasures. Additional tempest countermeasures, including facility and/or equipment shielding may also be a part of a potential solution, but is beyond the scope of this document. (U) Policy (U) The National Policy on the Control of Compromising Emanations (CNSSP 300) and its implementing instructions, tempest Countermeasures for Facilities (CNSSI 7000), and NONSTOP Countermeasures (NSTISSI 7001), establish the policy that certain systems and facilities that process NSI must be reviewed by a Certified tempest Technical Authority (CTTA). If such a review is required and the review determines that tempest countermeasures are required, the CTTA will consider a variety of methods that can be applied to the system/facility to achieve tempest security.

10 The RED/BLACK Guidance contained in this document will be considered by the CTTA along with other countermeasures, such as tempest suppressed equipment, filtering, and shielding, to determine the most cost-effective countermeasures to achieve tempest security. Only those specific criteria identified by the CTTA will be implemented. The authority to issue this Advisory Memorandum derives from National Security Directive 42, which outlines the roles and responsibilities for securing national security systems, consistent with applicable law, 12333, as amended, and other Presidential directives. Nothing in this Advisory Memorandum shall alter or supersede the authorities of the Director of National Intelligence. (U) Applicability (U) The Guidance contained herein, when specified by a CTTA, is applicable to Government departments, agencies, and contractors.
