Exfiltrating data from Air-Gapped Networks via Router LEDs

Thanks MGySgt (Join to see) for posting the article. Interesting concept. I like SSG Robert Webster's comment regarding access controls. What I have found, both in the US and Internationally, is the gulf between the IT Security and Physical Security silos in a company. The bigger the gulf, the more likely you can penetrate the company/network.

And this is why physical security to the wiring closet and other node locations is or should be a consideration in network security.
Even says so in most security guides that I know of.

Interesting concept, but note: "If the attacker has physical access to the target’s facility..."

Why would I keep my routers in an insecure location where someone can continuously monitor it with a camera?
