MIL-STD 188-125-1 details the minimum performance requirements for low-risk protection from mission-aborting damage due to HEMP attacks. The description of these threats are defined in MIL-STD-2169. MIL-STD-188-125-1 also addresses minimum testing requirements for demonstrating that prescribed performance has been achieved and for verifying that the installed protection subsystem provides the operationally required hardness for the completed facility.
The MIL-STD-188-125-1 test specification defines the design and testing criteria for specifically designated fixed ground-based facilities in HEMP-hardened, critical, time-urgent C4I networks. Facilities include subscriber terminals and data processing centers, transmitting and receiving communications stations, and relay facilities. MIL-STD-188-125-1 applies to both new construction and the retrofit of existing facilities.
Although only local portions of facility interconnects are addressed, it is assumed that survivable long-haul communications paths, fiber optic links, or other hardened interconnects between facilities will be provided as required for mission accomplishment. MIL-STD-188-125-1 can also be used for HEMP protection of other ground-based communications-electronics facilities that require HEMP hardening.
Keystone Compliance has completed numerous site surveys to determine the level of protection against HEMP attacks. Our team diligently completes the assessments and provides valuable feedback on any weaknesses that should be addressed. This feedback often includes suggestions for remediating any aperture points of entry (POE) and conductive points of entry. Our experience provides insight on improving protection as well as in determining specific locations within the facility that be more likely to serve as a point of entry.
