Grayson's organization is concerned about environmental attacks against their datacenter. What type of monitoring is best suited to detecting environmental attacks in a scenario like this?

Environmental monitoring involves things like temperature, water or flood sensors, and other detection capabilities that help organizations know if a natural disaster or other environmental issue has occurred. Video cameras cannot detect many of these and are not typically deployed to places where they would detect things like under-floor leaks or floods. Intrusion alarm systems do not provide this type of detection, and log analysis would require environmental monitoring sensors.
