Is Your Data Electromagnetically Secure?

Posted on 11/2/15 10:23 AM by Get Schooled in security, in Tips & Tricks

Servers and other electronic, magnetic, and wireless equipment emit and are affected by electromagnetic radiation. This gives rise to three potentially serious problems: snooping, interference, and electromagnetic pulse (EMP) susceptibility. Fortunately, all three problems can be easily mitigated with a faraday cage. The idea is that surrounding your equipment on all sides with a grounded metal cage that conducts electricity essentially shields the equipment from electrical energy. As long as the equipment doesn't touch the cage, wireless signals are prevented from getting in or out. Cages can also double as locked structures to keep unauthorized personnel away from sensitive equipment.
