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) could result in a lack of structural integrity and the undetected loss or compromise of classified material. Permanent construction materials; while not impenetrable, provide physical evidence of an attempted or actual intrusion into a secure room space. Construction materials and application techniques that are not permanent in nature can potentially be removed to allow for access to secure room space and then replaced by an intruder upon egress from the area. This effectively negates the detection capability afforded by permanent construction techniques and materials. Examples of non-permanent material would be modular walls that can be removed and replaced with ease or plywood board (or other materials) applied with screws or nails that can be removed from outside the secure room space and then replaced using common tools.

For secure rooms or areas (*containing inspectable SIPRNet assets) check: 1. That walls, floor, and roof construction of secure rooms are made of permanent construction materials; i.e., plaster, gypsum wallboard, metal panels, hardboard, wood, plywood, or other materials offering resistance to, and evidence of unauthorized entry into the area. Materials such as plywood must be attached in a manner so as not to enable easy removal of screws or nails to gain ingress and then replace upon egress. 2. The "True" ceiling shall be constructed of plaster, gypsum, wallboard material, hardware or any other acceptable material. TACTICAL ENVIRONMENT: This check is applicable where vaults or 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.
