Schneier: Either Everyone Is Cyber-secure Or No One Is 130

Posted by Soulskill from the nobody's-safe-except-the-amish dept.
Presto Vivace sends a new essay from Bruce Schneier called "The Democratization of Cyberattack." Quoting: When I was working with the Guardian on the Snowden documents, the one top-secret program the NSA desperately did not want us to expose was QUANTUM. This is the NSA's program for what is called packet injection--basically, a technology that allows the agency to hack into computers.Turns out, though, that the NSA was not alone in its use of this technology. The Chinese government uses packet injection to attack computers. The cyberweapons manufacturer Hacking Team sells packet injection technology to any government willing to pay for it. Criminals use it. And there are hacker tools that give the capability to individuals as well. ... We can't choose a world where the U.S. gets to spy but China doesn't, or even a world where governments get to spy and criminals don't. We need to choose, as a matter of policy, communications systems that are secure for all users, or ones that are vulnerable to all attackers. It's security or surveillance.

    There is just one problem to Bruce's argument: The largest and most powerful spy agency in the world disagrees with his fundamental assumption. We often forget that the NSA has two missions, and they are exactly the two things that Bruce argues cannot co-exist: To secure the computing infrastructure of the US against foreign espionage, and to provide espionage on foreign communication.
