Barely Skims the Surface
So much more to securing a data center. Need to broaden your approach to look at both environmental and security factors.
You location has a lot to do with the risks you face. Look at what types of severe weather events could impact that location.
If near an interstate, an accident with hazmat materials could shut it down. Look at the city water supply system and determine how many tank trucks you would need to keep going for a certain amount of time. Hopefully, you data center is not located anywhere near a high crime area, but do note what types of business and agencies are in your neighborhood. Do they attract people you do not want near your data center?
I spent many years reviewing the security of data centers. I could usually find a vulnerability that would enable a person with evil intent to enter the building and gain access to the critical areas. Often, the protection of the generator and diesel fuel storage is overlooked. Could critical air conditioning equipment be easily compromised?Too frequently, delivery trucks could drive up to the loading dock without being screened. They should be screened at a safe distance from the building.
Depending on police response when intrusion detection alarms are sounded is a recipe for disaster. It's good to know your police response times, both to a 9-1-1 and to an electronic alarm, relayed through a central station. Your guard force should be armed preferably with special police authority, and be well trained. The fire department and police should be given tours of your facility so they both understand its importance and have some plans for how to respond to an emergency.
