I work for a company which makes network devices. We&#x27;ve detected many hostile intrusions in our network. If you make hardware or software that runs in enterprise datacenters, someone is surely going to be trying to steal your source code to find exploits and possibly put backdoors in.<p>We use multi-factor authentication just to get in the corporate network and a separate, airlocked engineering network to store our IP. From what I&#x27;ve talked to from my colleagues at other major device manufacturers, this is becoming the industry standard (seven years ago I scoffed at Ericsson&#x27;s paranoia for having a sequestered engineering network. Turns out they just saw the attacks earlier than we did).<p>In our case, doesn&#x27;t seem to be the NSA. Looks more like China. Could easily be either one, or yet another party. This is the world we live in.
