Data Center Security

Physical controls are a crucial part of creating a secure environment


Emergency exit doors should also be covered with video cameras. The hardware should be located on the secure side only. Depending on local life safety and building codes, time-delayed egress hardware with loud horns should be used on these doors to give security personnel additional time to respond and to discourage their use except in an emergency.

Mission-critical facilities require redundancy in all aspects of the support infrastructure, which may entail redundant power grid connections and multiple fiber providers for communication. The connecting vaults for these multiple utilities are typically located at a distance away from the building and should be monitored through the facility’s security system. Finally, as a very important part of a data center’s critical support infrastructure, the security systems should be designed with redundancy as well.

In developing the security strategies for a data center, it is always better to plan for the worst and hope for the best.
