A security professional has reviewed a recent site assessment and has noted that a server room on the second floor of a building has Heating, Ventilation, and Air Conditioning (HVAC) intakes on the gr

Removing UV filters from HVAC intakes would increase risk by eliminating a biological/microbial filtration layer, and simply replacing the fire suppression without addressing the ground-level intake vulnerability leaves a significant physical attack vector unmitigated.

Adding more UV filters to supply and return ducts does not address the fundamental vulnerability of a ground-level HVAC intake being physically accessible and susceptible to deliberate contamination or physical tampering, leaving the root risk unresolved.

Adding physical security around HVAC intakes provides only a deterrent or detection control but does not eliminate the risk of airborne contaminants, flooding, or other environmental threats that a relocated/elevated intake would prevent, making it a less comprehensive mitigation.

Elevating the HVAC intake via a plenum or external shaft mitigates ground-level threats such as chemical or biological agent introduction, vandalism, and flooding by moving the intake to a less accessible height. Converting the server room fire suppression addresses a critical risk: Aero-K (a dry powder agent) can damage sensitive electronic equipment, and replacing it with a clean agent system (such as FM-200 or Halon alternative) protects both personnel and hardware while effectively suppressing fires without residue.
