Information Security (INFOSEC) - Secure Room Standards - BMS on Perimeter Doors
IS-02.01.08
CAT I
10
Where an IDS is used in lieu of 4-hour random checks, for secure rooms or collateral classified open storage areas containing SIPRNet assets, each perimeter door (primary and secondary) must be protected by a balanced magnetic switch (BMS) that meets the standards of UL 634.
NOTE: The alarm contact must be an actual BMS, which is defined as a "Triple Biased" alarm contact. Introduction of a foreign magnet by an intruder in an attempt to defeat the BMS will result in an alarm being sent. Simple and Dual Biased contacts are not BMS and will result in a finding.
Where an IDS is used in lieu of 4-hour random checks, for secure rooms or collateral classified open storage areas containing SIPRNet assets, each perimeter door (primary and secondary) shall be protected by a balanced magnetic switch (BMS) that meets the standards of UL 634.
NOTE: Ensure the alarm contact is an actual BMS, which is defined as a "Triple Biased" alarm contact. Introduction of a foreign magnet by an intruder in an attempt to defeat the BMS will result in an alarm being sent.
If used, Simple and Dual Biased contacts are not BMS and will result in a CAT II finding.
No alarm contacts on all doors is a CAT I finding.
TACTICAL ENVIRONMENT: This check is applicable where Secure Rooms are used to protect classified materials or systems in a tactical environment. 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.
