Introduction

Chapter 1. Introduction

A. Purpose This Intelligence Community (IC) Technical Specification sets forth the physical and technical security specifications and best practices for meeting standards of Intelligence

Community Standard (ICS) 705-1 (Physical and Technical Standards for Sensitive

Compartmented Information Facilities). When the technical specifications herein are applied to new construction and renovations of Sensitive Compartmented Information Facilities

(SCIFs), they shall satisfy the standards outlined in ICS 705-1 to enable uniform and reciprocal use across all IC elements and to assure information sharing to the greatest extent possible. This document is the implementing specification for Intelligence Community

Directive (ICD) 705, Physical and Technical Security Standards for Sensitive

Compartmented Information Facilities (ICS-705-1) and Standards for Accreditation and

Reciprocal Use of Sensitive Compartmented Information Facilities (ICS-705-2) and supersedes Director of Central Intelligence Directive (DCID) 6/9.

The specifications contained herein will facilitate the protection of Sensitive Compartmented

Information (SCI) against compromising emanations, inadvertent observation and disclosure by unauthorized persons, and the detection of unauthorized entry.

B. Applicability IC Elements shall fully implement this standard within 180 days of its signature.

SCIFs that have been de-accredited but controlled at the SECRET level (IAW 32 Code of

Federal Regulations (CFR) parts 2001 and 2004) for less than one year may be reaccredited one time using the previous standard. The IC SCIF repository shall indicate that the accreditation was based upon the previous standards.

UNCLASSIFIED Chapter 2

Risk Management

Chapter 2. Risk Management

A. Analytical Risk Management Process

1. The Accrediting Official (AO) and the Site Security Manager (SSM) should evaluate each proposed SCIF for threats, vulnerabilities, and assets to determine the most efficient countermeasures required for physical and technical security. In some cases, based upon that risk assessment, it may be determined that it is more practical or efficient to mitigate a standard. In other cases, it may be determined that additional security measures should be employed due to a significant risk factor.

2. Security begins when the initial requirement for a SCIF is known. To ensure the integrity of the construction and final accreditation, security plans should be coordinated with the AO before construction plans are designed, materials ordered, or contracts let.

a) Security standards shall apply to all proposed SCI facilities and shall be coordinated with the AO for guidance and approval. Location of facility construction and or fabrication does not exclude a facility from security standards and or review and approval by the AO. SCI facilities include but are not limited to fixed facilities, mobile platforms, prefabricated structures, containers, modular applications or other new or emerging applications and technologies that may meet performance standards for use in SCI facility construction.

b) Mitigations are verifiable, non-standard methods that shall be approved by the

AO to effectively meet the physical/technical security protection level(s) of the standard. While most standards may be effectively mitigated via non-standard construction, additional security countermeasures and/or procedures, some standards are based upon tested and verified equipment (e.g., a combination lock meeting Federal Specification FF-L 2740A) chosen because of special attributes and could not be mitigated with non-tested equipment. The AO‟s approval is documented to confirm that the mitigation is at least equal to the physical/technical security level of the standard.

c) Exceeding a standard, even when based upon risk, requires that a waiver be processed and approved in accordance with ICD 705.

3. The risk management process includes a critical evaluation of threats, vulnerability, and assets to determine the need and value of countermeasures. The process may include the following:

a) Threat Analysis. Assess the capabilities, intentions, and opportunity of an adversary to exploit or damage assets or information. Reference the threat information provided in the National Threat Identification and Prioritization

Assessment (NTIPA) produced by the National Counterintelligence Executive

(NCIX) for inside the U.S. and/or the Overseas Security Policy Board (OSPB), Security Environment Threat List (SETL) for outside the U.S. to determine technical threat to a location. When evaluating for TEMPEST, the Certified

TEMPEST Technical Authorities (CTTA) shall use the National Security Agency

Information Assurance (NSA IA) list as an additional resource for specific technical threat information. NOTE: These threat documents are classified.

Associating the threat level or other threat information with the SCIF location

(including country, city, etc.) will normally carry the same classification level identified in the threat document. Ensure that SCIF planning documents and discussions that identify threat with the country or SCIF location are protected accordingly. It is critical to identify other occupants of common and adjacent buildings. (However, do not attempt to collect information against U.S. persons in violation of Executive Order (EO) 12333.) In areas where there is a diplomatic presence of high and critical threat countries, additional countermeasures may be necessary.

b) Vulnerability Analysis. Assess the inherent susceptibility to attack of a procedure, facility, information system, equipment, or policy.

c) Probability Analysis. Assess the probability of an adverse action, incident, or attack occurring.

d) Consequence Analysis. Assess the consequences of such an action (expressed as a measure of loss, such as cost in dollars, resources, programmatic effect/mission impact, etc.).

B. Security in Depth (SID)

1. SID describes the factors that enhance the probability of detection before actual penetration to the SCIF occurs. The existence of a layer or layers of security that offer mitigations for risks may be accepted by the AO. An important factor in determining risk is whether layers of security already exist at the facility. If applied, these layers may, with AO approval, alter construction requirements and extend security alarm response time to the maximum of 15 minutes. Complete documentation of any/all SID measures in place will assist in making risk decisions necessary to render a final standards decision.

2. SID is mandatory for SCIFs located outside the U.S. due to increased threat.

3. The primary means to achieve SID are listed below and are acceptable. SID requires that at least one of the following mitigations is applied:

a) Military installations, embassy compounds, U.S. Government (USG) compounds, or contractor compounds with a dedicated response force of U.S.

persons.

b) Controlled buildings with separate building access controls, alarms, elevator controls, stairwell controls, etc., required to gain access to the buildings or elevators. These controls shall be fully coordinated with a formal agreement or managed by the entity that owns the SCIF.

c) Controlled office areas adjacent to or surrounding SCIFs that are protected by alarm equipment installed in accordance with manufacturer‟s instructions. These controls shall be fully coordinated with a formal agreement or managed by the entity that owns the SCIF.

d) Fenced compounds with access controlled vehicle gate and/or pedestrian gate.

e) The AO may develop additional strategies to mitigate risk and increase probability of detection of unauthorized entry.

C. Compartmented Area (CA)

1. Definition

A CA is an area, room, or a set of rooms within a SCIF that provides controlled separation between control systems, compartments, sub-compartments, or Controlled

Access Programs.

2. Requirements

a) The CA shall be approved by the AO with the concurrence of the CA Program

Manager or designee. The CA Checklist (Chapter 13) shall be used to request approval.

b) Any construction or security requirements above those listed herein require prior approval from the element head as described in ICS 705-2.

3. Access Control

a) Access control to the CA may be accomplished by visual recognition or mechanical/electronic access control devices.

b) Spin-dial combination locks shall not be installed on CA doors.

c) Independent alarm systems shall not be installed in a CA.

4. Visual Protection of CA Workstations

If compartmented information will be displayed on a computer terminal or group of terminals in an area where everyone is not accessed to the program, the following measures may be applied to reduce the ability of “shoulder surfing” or inadvertent viewing of compartmented information:

Position the computer screen away from doorway/cubicle opening.

Use a polarizing privacy screen.

Use partitions and/or signs.

Existing private offices or rooms may be used but may not be a mandatory requirement.

5. Closed Storage

When the storage, processing, and use of compartmented information, product, or deliverables is required, and all information shall be stored while not in use, then all of the following shall apply:

a) Access and visual controls identified above shall be the standard safeguard.

b) Compartmented information shall be physically stored in a General Services

Administration (GSA) approved safe.

6. Open Storage

In rare instances when open storage of information is required, the following apply:

a) If the parent SCIF is accredited for open storage, a private office with access control on the door is adequate physical security protection.

b) If the parent SCIF has been built and accredited for closed storage, then the

CA perimeter shall be constructed and accredited to open storage standards.

c) The CA AO may approve open or closed storage within the CA. Storage requirements shall be noted in both the CA Fixed Facility Checklist (FFC) and, if appropriate, in a Memorandum of Understanding (MOU).

7. Acoustic and Technical Security

a) All TEMPEST, administrative telephone, and technical surveillance countermeasure (TSCM) requirements for the parent SCIF shall apply to the CA and shall be reciprocally accepted.

b) When compartmented discussions are required, the following apply:

(1) Use existing rooms that have been accredited for SCI discussions.

(2) Use administrative procedures to restrict access to the room during conversations.

UNCLASSIFIED Chapter 3
