Associated with IA controls: PESS-1
Failure to meet standards for ensuring that there is structural integrity of the physical perimeter surrounding a secure room (AKA: collateral classified open storage area) IAW DoD Manual 5200.01, Volume 3 could result in the undetected loss or compromise of classified material.
For secure rooms or areas (*containing inspectable SIPRNet assets) check windows as follows: 1. Window placement in secure rooms should be minimal. Ideally, there should be no large or entirely glass walls; although this will not automatically result in a finding if the glass is hardened to the same degree as the contiguous walls and properly obscured from outside viewing. 2. Windows that are less than 18 feet above the ground measured from the bottom of the window, or are easily accessible by means of objects directly beneath the windows shall be constructed from or covered with materials that provide protection from forced entry. The protection provided to the windows need be no stronger than the strength of the contiguous walls. Hurricane rated windows, ballistic proof windows, non-opening double or triple pane windows, etc. should be considered acceptable as equivalent to contiguous walls. Welded steel bars attached to the structure surrounding the window may also be used for hardening. 3. All windows within 18 feet of ground level, that are capable of being opened from inside the protected space shall also be protected by an IDS, either independently or by motion detection sensors in the space. 4. Windows will be covered with curtains, screens or otherwise limit visibility into the secure room space when classified equipment, documents or media can be viewed from outside the area. TACTICAL ENVIRONMENT: This check is applicable where secure rooms are used to protect classified materials or systems. The only exception will be for urgent (short term) tactical operations or other contingency situations where fixed facilities and equipment are not yet present or incapable of being used.
