How DRM Makes Us All Less Safe

May 6th is the official Day Against DRM. I’m a bit late writing anything about it, but I wanted to highlight this great post by Parker Higgins about an aspect of DRM that is rarely discussed: how DRM makes us less safe. We’ve talked a lot lately about how the NSA and its surveillance efforts have made us all less safe, but that’s also true for DRM.
DRM on its own is bad, but DRM backed by the force of law is even worse. Legitimate, useful, and otherwise lawful speech falls by the wayside in the name of enforcing DRM—and one area hit the hardest is security research.
Section 1201 of the Digital Millennium Copyright Act (DMCA) is the U.S. law that prohibits circumventing “technical measures,” even if the purpose of that circumvention is otherwise lawful. The law contains exceptions for encryption research and security testing, but the exceptions are narrow and don’t help researchers and testers in most real-world circumstances. It’s risky and expensive to find the limits of those safe harbors.
As a result, we’ve seen chilling effects on research about media and devices that contain DRM. Over the years, we’ve collected dozens of examples of the DMCA chilling free expression and scientific research. That makes the community less likely to identify and fix threats to our infrastructure and devices before they can be exploited.
That post also reminds us of Cory Doctorow’s powerful speech about how DRM is the first battle in the war on general computing. The point there is that, effectively, DRM is based on the faulty belief that we can take a key aspect of computing out of computing, and that, inherently weakens security as well. Part of this is the nature of DRM, in that it’s a form of weak security — in that it’s intended purpose is to stop you from doing something you might want to do. But that only serves to open up vulnerabilities (sometimes lots of them), by forcing your computer to (1) do something in secret (otherwise it wouldn’t be able to stop you) and (2) to try to stop a computer from doing basic computing. And that combination makes it quite dangerous — as we’ve seen a few times in the past.
DRM serves a business purpose for the companies who insist on it, but it does nothing valuable for the end user and, worse, it makes their computers less safe.
