Attachment 2 – Collaboration Peripherals in SCIF or SAPF DoD Secure Spaces
Component Senior Information Security Officers (SISO), in coordination with the
appropriate Sensitive Compartmented Information Facility (SCIF) Accrediting Official (SCIF
AO) or the Special Access Program Facility (SAPF) Accrediting Official (SAPF AO), must
establish standard operating procedures for the use of any collaboration peripherals approved in
accordance with this attachment. In SCIF-based situations where the Component with
cognizance over the computer, the Component that accredited the SCIF, or the Component that
occupies the SCIF differ, the Component SISO, SCIF AO, and Cognizant Security Authority
must coordinate with each other. In similar SAPF-based situations, the Component SISO, SAPF
AO, and Program Security Officer must coordinate with each other. Universal serial bus (USB)
collaboration peripherals that have been connected to classified computers may not subsequently
be connected to unclassified computers, or vice versa. Personally- or privately-owned headsets,
microphones, desktop telephone units, and webcams are prohibited in DoD secure spaces.
Microphones
Wireless headsets, with or without microphone capability, are prohibited in DoD secure
spaces. Headsets with noise-cancelling capabilities contain embedded microphones and are
considered headsets with microphones regardless of any other user-accessible microphone
capability. Microphone capabilities built into unclassified computers are prohibited in DoD
secure spaces unless physically disabled

. Wired external headsets with a microphone capability
that is not controlled by a push-to-talk (PTT) feature
5
or a telephone security group (TSG)-
approved positive disconnection device (PDD) that operates by physical (not software) means
(referred to jointly as “PTT/PDD”) are prohibited when attached to an unclassified computer in a
DoD secure space. The use of wired externally-connected headsets with microphone capability
on unclassified desktop telephone units and computer-based “softphone” telephones in DoD
secure spaces must include a PTT/PDD capability (either in the headset itself, physically wired
in-line with the headset, or integrated into the desktop telephone unit) in accordance with
Committee on National Security Instructions 5000, 5001, 5002, and applicable annexes.
Component SISOs may authorize the use of wired, externally-connected headsets with
PTT/PDD microphone capabilities on unclassified computers in SCIFs and SAPFs, subject to
restriction by the SCIF AO and SAPF AO respectively. Component SISOs may authorize the
use of built-in microphone capabilities or wired externally-connected headsets with microphone
capabilities on classified computers in SCIFs and SAPFs, subject to restriction by the SCIF AO
and SAPF AO respectively. Wired externally-connected headsets without microphone capability
are authorized on classified and unclassified computers in SCIFs and SAPFs.

“Physically disabled” is a method of disablement that cannot be made or reversed, by privileged or non-privileged
or administrators, through logical settings configured by software (such as applications, operating systems,
firmware, basic input/output system (BIOS), or unified extensible firmware interface (UEFI)), or otherwise
configured in volatile or non-volatile memory or storage.
5
“Push to talk” is a capability that requires the user of a device to depress a physical button somewhere on the
device to physically enable the device’s microphone, and that automatically physically disables the microphone
when the button is released. The microphone remains physically disabled whenever the button is not depressed.
