Small Rooms / SCIF

When viewed as a six sided enclosure, the breech points of most rooms can be easily identified. Windows are vulnerable to laser listening devices, ductwork can easily channel sound to adjacent areas and doors form an obvious weak point. Sound transmission through utility penetrations, access floor cavities and above suspended ceilings can create a lack of confidential privacy.
