FBI-Sponsored Backdoors

From a review of Susan Landau’s Surveillance or Security?:

To catch up with the new technologies of malfeasance, FBI director Robert Mueller traveled to Silicon Valley last November to persuade technology companies to build “backdoors” into their products. If Mueller’s wish were granted, the FBI would gain undetected real-time access to suspects’ Skype calls, Facebook chats, and other online communications­and in “clear text,” the industry lingo for unencrypted data. Backdoors, in other words, would make the Internet—and especially its burgeoning social media sector—”wiretappable.”

This is one of the cyber threats I talked about last week: insecurities deliberately created in some mistaken belief that they will stop crime. Once you build a backdoor into a product, you need to ensure that only the good guys use that backdoor, and only when they should. We’d all be much more secure if the backdoor didn’t exist at all.

The Efficacy of Post-9/11 Counterterrorism

This is an interesting article. The authors argue that the whole war-on-terror nonsense is useless—that’s not new—but that the security establishment knows it doesn’t work and abandoned many of the draconian security measures years ago, long before Obama became president. All that’s left of the war on terror is political, as lawmakers fund unwanted projects in an effort to be tough on crime.

I wish it were true, but I don’t buy it. The war on terror is an enormous cash cow, and law enforcement is spending the money as fast as it can get it. It’s also a great stalking horse for increases in police powers, and I see no signs of agencies like the FBI or the TSA not grabbing all the power they can.

The second half of the article is better. The authors argue that openness, not secrecy, improves security:

The worst mistakes and abuses of the War on Terror were possible, in no small part, because national security is still practiced more as a craft than a science. Lacking rigorous evaluations of its practices, the national security establishment was particularly vulnerable to the panic, grandiosity, and overreach that colored policymaking in the wake of 9/11.

To avoid making those sorts of mistakes again, it is essential that we reimagine national security as an object of scientific inquiry. Over the last four centuries, virtually every other aspect of statecraft—from the economy to social policy to even domestic law enforcement—has been opened up to engagement with and evaluation by civil society. The practice of national security is long overdue for a similar transformation.

Maintaining the nation’s security of course will continue to require some degree of secrecy. But there is little reason to think that appropriate secrecy is inconsistent with a fact-based culture of robust and multiplicative inquiry. Indeed, to whatever partial extent that culture already exists within the national security establishment, it has led the move away from many of the counterproductive security measures established after 9/11.

Yet, in the ten years that Congress has been debating issues like coercive interrogation, ethnic profiling, and military tribunals, the House and Senate Intelligence committees, which have all the proper security clearances to evaluate such questions, have never established any formal process to consistently evaluate and improve the effectiveness of U.S. counterterrorism measures.

Establishing proper oversight and evaluation of the efficacy of our security practices will not come easily, for the security craft guards its claims to privileged knowledge jealously. But as long as the practice of security remains hidden behind a veil of classified documents and accepted wisdoms handed down from generation to generation of security agents, our national security apparatus will never become fully modern.

Here’s the report the article was based on.

Cryptography and Wiretapping

Matt Blaze analyzes the 2010 U.S. Wiretap Report.

In 2000, government policy finally reversed course, acknowledging that encryption needed to become a critical part of security in modern networks, something that deserved to be encouraged, even if it might occasionally cause some trouble for law enforcement wiretappers. And since that time the transparent use of cryptography by everyday people (and criminals) has, in fact, exploded. Crypto software and algorithms, once categorized for arms control purposes as a “munition” alongside rocket launchers and nuclear triggers, can now be openly discussed, improved and incorporated into products and services without the end user even knowing that it’s there. Virtually every cellular telephone call is today encrypted and effectively impervious to unauthorized over-the-air eavesdropping. Web transactions, for everything from commerce to social networking, are now routinely encrypted end-to-end. (A few applications, particularly email and wireline telephony, remain stubbornly unencrypted, but they are increasingly the exception rather than the rule.)

So, with this increasing proliferation of eavesdrop-thwarting encryption built in to our infrastructure, we might expect law enforcement wiretap rooms to have become quiet, lonely places.

But not so fast: the latest wiretap report identifies a total of just six (out of 3194) cases in which encryption was encountered, and that prevented recovery of evidence a grand total of … (drumroll) … zero times. Not once. Previous wiretap reports have indicated similarly minuscule numbers.

I second Matt’s recommendation of Susan Landau’s book: Surveillance or Security: The Risks Posed by New Wiretapping Technologies (MIT Press, 2011). It’s an excellent discussion of the security and politics of wiretapping.

Fingerprint Scanner that Works at a Distance

Scanning fingerprints from six feet away.

Slightly smaller than a square tissue box, AIRprint houses two 1.3 megapixel cameras and a source of polarized light. One camera receives horizontally polarized light, while the other receives vertically polarized light. When light hits a finger, the ridges of the fingerprint reflect one polarization of light, while the valleys reflect another. “That’s where the real kicker is, because if you look at an image without any polarization, you can kind of see fingerprints, but not really well,” says Burcham. By separating the vertical and the horizontal polarization, the device can overlap those images to produce an accurate fingerprint, which is fed to a computer for verification.

No information on how accurate it is, but it’ll only get better.
