SUMMARY OF REVISIONS

This document was substantially revised and must be completely reviewed. This revision was substantially rewritten to change the emphasis for EMSEC from a stand-alone program to an integral part of IP. It deletes references to acquisition (paragraph 2), and implements the EMSEC certification part of the certification and accreditation process (paragraph 9). It also clarifies application of the instruction to those contractors who contract to perform Air Force functions (paragraph 2). It clarifies the three EMSEC assessments (paragraph 2.1.1) and three EMSEC countermeasures reviews (paragraph 5), and the process to authenticate them (paragraphs 4.3.2, 5.3, 6, 8, and 9). It adds the basic steps for validating EMSEC countermeasures reviews (paragraph 6), adds the requirement for the user to notify the wing IP office to make the EMSEC inspection (paragraph 4.2), and removes the annual requirement for EMSEC inspections (paragraph 8). It provides instructions for the EMSEC certification (paragraph 9) and removes the instruction for a reassessment during an annual inspection (paragraph 8). It makes one level of authority for approving temporary waivers (paragraph 11.2.2.1.1). It replaces reference to the term “command, control, communications, and computer (C4)” with “information systems”. It deletes Air Force Communications Security (AFCOMSEC) Form 7001, Emission Security Assessment/Emission Security Countermeasures Review, from being prescribed by this publication (it is now prescribed by AFSSI 7010, [S] The Emission Security Assessment [U]).

### Section A - The Emission Security Program

1. Introduction. The Air Force EMSEC process has experienced many changes. Although these changes were attempts to meet the variances of a dynamic world, they require security protection measures far beyond the needs of the average user. In the past, EMSEC tended to stand alone; however, IP now requires a more balanced approach not only to the control of compromising emanations, NONSTOP, and HIJACK, but to communications security (COMSEC); COMPUSEC; and SATE as well. The prime objective of EMSEC is to identify requirements from the standpoint of IP risk management principles and provide the appropriate protection at the least possible, or no, cost. Key to this process is a partnership between the wing IP office and the user. The wing IP office assesses the need for EMSEC as part of IP; determines the required countermeasures; advises commanders of vulnerabilities, threats, and risks; and recommends a practical and feasible course of action to the wing commander. The user applies identified countermeasures.

2. Emission Security Requirements. Air Force organizations and contractors doing business as the Air Force, whether procuring or using systems to process classified national security information, must apply EMSEC proportional to the threat of exploitation.

> 2.1. They must consider the potential damage to national security if classified national security information is compromised, and:

> > 2.1.1. Assess the need for EMSEC for each aspect (control of compromising emanations, NON-STOP, and HIJACK) and determine the specific countermeasures before beginning architectural engineering and facility design, procuring systems, or beginning engineering and installation.

> > 2.1.2. Implement or apply required countermeasures before using systems to process classified national security information.

> > 2.1.3. Operate and maintain systems to preserve the integrity of required countermeasures.

> 2.2. Processing classified national security information without complying with the above requirements is a reportable security incident under AFI 31-401, Managing the Information Security Program, except as allowed for by waiver in paragraph 11.

3. Emission Security Process. Assess equipment and facilities to determine the need for EMSEC (control of compromising emanations, NONSTOP, and HIJACK); determine, validate, and implement or apply the required countermeasures; and periodically reassess EMSEC requirements. The following paragraphs further define this process (see Attachment 2).

4. Emission Security Assessments. This process determines the need for EMSEC for a system that processes classified national security information.

> 4.1. The using Air Force organization determines if the system will process classified national security information.

> 4.2. If the system will process classified national security information, the using organization must contact the wing IP office.

> > 4.2.1. The wing IP office makes the EMSEC assessment for wing-level systems and programs.

> > 4.2.2. The major command (MAJCOM) IP office makes the EMSEC assessment for MAJCOM-level programs.

> > 4.2.3. The lead MAJCOM IP office, or the certified TEMPEST technical authority (CTTA), makes the EMSEC assessments for Air Force-level programs.

> > 4.2.4. For Special Category (SPECAT) information, the CTTA makes the EMSEC assessments.

> 4.3. All IP offices:

> > 4.3.1. Use AFSSI 7010 to make the assessments.

> > 4.3.2. Document the EMSEC assessment on AFCOMSEC Form 7001 according to AFSSI 7010.

5. Emission Security Countermeasures Reviews. This process determines the needed control of compromising emanations, NONSTOP, and HIJACK countermeasures for a system that processes classified national security information.

> 5.1. If the EMSEC assessment determined the need for the control of compromising emanations, NONSTOP, or HIJACK, make the appropriate countermeasures review. Use Air Force Systems Security Memorandum (AFSSM) 7011, The Emission Security Countermeasures Review to make each review.

> 5.2. The same IP office that made the EMSEC assessments makes the EMSEC countermeasures review.

> 5.3. Whenever possible, document the EMSEC countermeasures reviews on the same AFCOMSEC Form 7001 used for the EMSEC assessments. Where this is not possible, complete an additional AFCOMSEC Form 7001 for the countermeasures review with an appropriate reference to the associated assessment.

6. Validation Requirements. The CTTA must validate the EMSEC countermeasures review because of the costs involved in applying countermeasures to some facilities and the cost of some countermeasures. Validate EMSEC countermeasures reviews according to AFSSM 7011. Whenever possible, document the validation on the same AFCOMSEC Form 7001 used for the EMSEC countermeasures review. Where this is not possible, complete an additional AFCOMSEC Form 7001 for the validation with an appropriate reference to the associated assessment and countermeasures review.

7. Applying Countermeasures. The user applies, implements, and maintains the required countermeasures identified by the EMSEC countermeasures review. Notify the wing IP office when completed.

8. Emission Security Inspection. Upon notification from the user, the wing IP office makes an EMSEC inspection to make sure the required EMSEC countermeasures are effectively applied or implemented. The EMSEC countermeasures review is the basis for the EMSEC inspection. The user must correct deficiencies discovered by an EMSEC inspection or request a temporary or permanent waiver before processing classified national security information.

9. Emission Security Certification. As a part of the certification and accreditation process, the wing IP office certifies all required EMSEC countermeasures are in place after the EMSEC inspection. Certify the system as meeting EMSEC requirements according to AFSSM 7011. Whenever possible, document the EMSEC certification on the same AFCOMSEC Form 7001 used for the EMSEC countermeasures review. Where this is not possible, complete an additional AFCOMSEC Form 7001 for the certification with an appropriate reference to the associated assessment, countermeasures review, and validation.

10. Reassessing Requirements. Reassess EMSEC requirements when required by a COMPUSEC risk analysis, the threat changes, or when the classification level of the information changes. Make a reassessment by reviewing and confirming the information on the AFCOMSEC Form 7001 is still valid. You do not need a new AFCOMSEC Form 7001 for changes such as equipment, office, room, or building changes, that do not change the outcome of the EMSEC assessment or countermeasures review. Make pen and ink changes instead. If the form gets too messy, re-accomplish the form.

11. Waivers. There are two kinds of EMSEC waivers: temporary and permanent.

> 11.1. AFCOMSEC Form 3331, Request for Waiver From Information Protection Criteria. Use this form to document and request either a temporary (see Attachment 3) or permanent waiver (see Attachment 4). Attach a copy of the EMSEC countermeasures review.

> 11.2. Temporary Waiver. A temporary waiver allows the processing of classified national security information when the user is not able to implement or apply all required EMSEC countermeasures. A temporary waiver is valid for one year to allow the user to accomplish the mission while they implement or apply all required EMSEC countermeasures.

> > 11.2.1. Conditions. The following conditions must exist before processing a temporary waiver:

> > > 11.2.1.1. All required EMSEC countermeasures were not installed or applied during installation.

> > > 11.2.1.2. Operation is required for mission accomplishment.

> > > 11.2.1.3. The user cannot install all required EMSEC countermeasures before system turn-on.

> > 11.2.2. Processing a Temporary Waiver. The user originates the request for a temporary waiver, then sends it to the wing IP office for coordination, and approval or disapproval by the appropriate authority.

> > > 11.2.2.1. The control of compromising emanations.

> > > > 11.2.2.1.1. For collateral information, the approval authority for the temporary waiver is the designated approving authority (DAA).

> > > > 11.2.2.1.2. For SPECAT information, process the temporary waiver through the SPECAT EMSEC person to the SPECAT DAA.

> > > > 11.2.2.1.3. For Global Command and Control System (GCCS) information, process the temporary waiver through the MAJCOM IP office to the GCCS DAA.

> > > 11.2.2.2. NONSTOP and HIJACK. The CTTA approves all NONSTOP and HIJACK temporary waivers. NOTE: The terms NONSTOP and HIJACK have classified definitions (see AFSSI 7010).

> > > > 11.2.2.2.1. For collateral information, the approval authority is the Air Force CTTA.

> > > > 11.2.2.2.2. For SPECAT information, process the temporary waiver through the SPECAT EMSEC person to HQ AFCA/GCIS.

> > > > 11.2.2.2.3. For GCCS information, process the temporary waiver through the MAJCOM IP office to HQ AFCA/GCIS.

> > 11.2.3. Temporary Waiver Renewals. A temporary waiver is renewable for one year only if the user is making an active effort to correct the problem; otherwise do not renew it. Process a renewal according to paragraph 11.2.2 before the current temporary waiver expires. Only two renewals are permitted.

> > 11.2.4. Temporary Waiver Cancellations. Cancel the temporary waiver after applying the required EMSEC countermeasures (see Attachment 3 for instructions).

> > 11.2.5. Temporary Waiver Copies. Forward a copy of all temporary waivers, including renewals and cancellations, to the MAJCOM IP office or SPECAT EMSEC person and HQ AFCA/GCIS.

> 11.3. Permanent Waiver. Only a CTTA may waive a specific EMSEC countermeasure. Such things as an extremely low volume of classified national security information, a low level of classification, disproportionate costs, impossible to do, or other conditions that make the application of the EMSEC countermeasure seem inappropriate to the wing IP office, are the basis for a permanent waiver. Permanent waivers have no expiration date and are valid as long as the conditions for approval do not change. Process requests as follows:

> > 11.3.1. The user initiates the request and forwards the request to the wing IP office for review.

> > 11.3.2. The wing IP office reviews the request for validity and, if valid, forwards the request to the MAJCOM IP office or SPECAT EMSEC person for review.

> > 11.3.3. The MAJCOM IP office or SPECAT EMSEC person reviews the request and, if valid, forwards the request, along with appropriate supportive comments, to HQ AFCA/GCIS.
