Zorluk: ZorPhysical Security Controls and Environmental Measures

A network facility security officer is auditing physical defense mechanisms and environmental protection systems across an enterprise data center. Match each physical security or environmental vulnerability scenario on the left with the corresponding technical control on the right that provides appropriate mitigation.

  • Risk of side-channel electromagnetic eavesdropping on sensitive wireless operations from outside the physical building boundary.Faraday cage / RF shielding enclosure
  • Risk of thermal shock, electrical shorting, and equipment destruction during fire suppression inside high-density server racks.Clean-agent gaseous fire suppression system (e.g., FM-200 or Novec 1230)
  • Risk of single-corded network switches experiencing unexpected power loss upon primary circuit branch failure.Rack-mounted Automatic Transfer Switch (ATS)
  • Risk of undetected fluid accumulation beneath raised access flooring due to cooling pipe condensation or HVAC drain pan overflow.Conductive liquid-detection sensing cable array

Cevap

Electromagnetic eavesdropping matches with Faraday cage / RF shielding enclosure; thermal shock and equipment destruction from fire matches with Clean-agent gaseous fire suppression system; single-corded power failure matches with Rack-mounted Automatic Transfer Switch (ATS); and undetected sub-floor fluid accumulation matches with Conductive liquid-detection sensing cable array.
Each risk factor requires a targeted physical or environmental control: RF shielding blocks electromagnetic leakage; clean-agent gases put out electrical fires cleanly; automatic transfer switches grant dual-feed resilience to single-corded network hardware; and liquid-detection cables spot hidden sub-floor leaks.

Adım Adım Çözüm

1
Analyze the electromagnetic emissions scenario.
Identified electromagnetic leakage outside building boundaries as an RF security threat (TEMPEST).
Faraday cages and metallic mesh/enclosures block electromagnetic signals and RF propagation.
2
Analyze fire protection requirements for energized electronics.
Determined that water sprinklers cause shorts and chemical powders damage equipment.
Clean-agent gaseous systems extinguish fires without liquid residue or electrical conductivity.
3
Evaluate power redundancy for single-corded hardware.
Selected a mechanism that allows legacy single-cord hardware to connect to dual utility feeds.
Rack-mounted ATS units draw from dual circuits and rapidly switch feeds if primary power fails.
4
Identify early warning systems for fluid leaks under raised floors.
Selected sub-floor moisture sensing arrays.
Conductive sensing cables placed under raised floors detect localized moisture immediately upon contact.
