Another breathless fearmongering. "threatens"? No, I don't think network booting is even all that common outside of extremely niche scenarios.

Instead, it applies only to organizations with machines that boot from local networks, or conceivably from Internet-connected resources.

Who is PXE-booting over the open Internet!?

Several large bare-metal hosting companies. Not over the open Internet, but that doesn't matter if the management networks are shared and the price of admission a single server rental.

It's incredibly common though? I've run across it and I work on games and client software, not server stuff.
