Focus on the Threat
In the wake of Saturday’s failed Times Square car bombing, it’s natural to ask how we can prevent this sort of thing from happening again. The answer is stop focusing on the specifics of what actually happened, and instead think about the threat in general.
Think about the security measures commonly proposed. Cameras won’t help. They don’t prevent terrorist attacks, and their forensic value after the fact is minimal. In the Times Square case, surely there’s enough other evidence—the car’s identification number, the auto body shop the stolen license plates came from, the name of the fertilizer store—to identify the guy. We will almost certainly not need the camera footage. The images released so far, like the images in so many other terrorist attacks, may make for exciting television, but their value to law enforcement officers is limited…
The Meaning of Trust
Security technologist and author Bruce Schneier looks at the age-old problem of insider threat
Rajendrasinh Makwana was a UNIX contractor for Fannie Mae. On October 24, he was fired. Before he left, he slipped a logic bomb into the organisation’s network. The bomb would have “detonated” on January 31. It was programmed to disable access to the server on which it was running, block any network monitoring software, systematically and irretrievably erase everything, and then replicate itself on all 4,000 Fannie Mae servers. Court papers claim the damage would have been in the millions of dollars.
Luckily, another programmer discovered the script a week later, and disabled it…
Scanners, Sensors are Wrong Way to Secure the Subway
We'll spend millions on new technology, and terrorists will just adapt
People intent on preventing a Moscow-style terrorist attack against the New York subway system are proposing a range of expensive new underground security measures, some temporary and some permanent.
They should save their money—and instead invest every penny they’re considering pouring into new technologies into intelligence and old-fashioned policing.
Intensifying security at specific stations only works against terrorists who aren’t smart enough to move to another station. Cameras are useful only if all the stars align: The terrorists happen to walk into the frame, the video feeds are being watched in real time and the police can respond quickly enough to be effective. They’re much more useful …
Google And Facebook's Privacy Illusion
These companies and others say privacy erosion is inevitable--but they're making it so.
In January Facebook Chief Executive, Mark Zuckerberg, declared the age of privacy to be over. A month earlier, Google Chief Eric Schmidt expressed a similar sentiment. Add Scott McNealy’s and Larry Ellison’s comments from a few years earlier, and you’ve got a whole lot of tech CEOs proclaiming the death of privacy—especially when it comes to young people.
It’s just not true. People, including the younger generation, still care about privacy. Yes, they’re far more public on the Internet than their parents: writing personal details on Facebook, posting embarrassing photos on Flickr and having intimate conversations on Twitter. But they take steps to protect their privacy and vociferously complain when they feel it violated. They’re not technically sophisticated about privacy and make mistakes all the time, but that’s mostly the fault of companies and Web sites that try to manipulate them for financial gain…
Should the Government Stop Outsourcing Code Development?
This essay appeared as the second half of a point/counterpoint with Marcus Ranum. Marcus’s half is here.
Information technology is increasingly everywhere, and it’s the same technologies everywhere. The same operating systems are used in corporate and government computers. The same software controls critical infrastructure and home shopping. The same networking technologies are used in every country. The same digital infrastructure underpins the small and the large, the important and the trivial, the local and the global; the same vendors, the same standards, the same protocols, the same applications…
Spy Cameras Won't Make Us Safer
On January 19, a team of at least 15 people assassinated Hamas leader Mahmoud al-Mabhouh. The Dubai police released video footage of 11 of them. While it was obviously a very professional operation, the 27 minutes of video is fascinating in its banality. Team members walk through the airport, check in and out of hotels, get in and out of taxis. They make no effort to hide themselves from the cameras, sometimes seeming to stare directly into them. They obviously don’t care that they’re being recorded, and—in fact—the cameras didn’t prevent the assassination, nor as far as we know have they helped as yet in identifying the killers…
U.S. Enables Chinese Hacking of Google
Google made headlines when it went public with the fact that Chinese hackers had penetrated some of its services, such as Gmail, in a politically motivated attempt at intelligence gathering. The news here isn’t that Chinese hackers engage in these activities or that their attempts are technically sophisticated—we knew that already—it’s that the U.S. government inadvertently aided the hackers.
In order to comply with government search warrants on user data, Google created a backdoor access system into Gmail accounts. This feature is what the Chinese hackers exploited to gain access…
Fixing Intelligence Failures
President Obama in his speech last week rightly focused on fixing the intelligence failures that resulted in Umar Farouk Abdulmutallab being ignored, rather than on technologies targeted at the details of his underwear-bomb plot. But while Obama’s instincts are right, reforming intelligence for this new century and its new threats is a more difficult task than he might like.
We don’t need new technologies, new laws, new bureaucratic overlords, or – for heaven’s sake – new agencies. What prevents information sharing among intelligence organizations is the culture of the generation that built those organizations…
Stop the Panic on Air Security
The Underwear Bomber failed. And our reaction to the failed plot is failing as well, by focusing on the specifics of this made-for-a-movie plot rather than the broad threat. While our reaction is predictable, it’s not going to make us safer.
We’re going to beef up airport security, because Umar Farouk AbdulMutallab allegedly snuck a bomb through a security checkpoint. We’re going to intensively screen Nigerians, because he is Nigerian. We’re going to field full body scanners, because they might have noticed the PETN that authorities say was hidden in his underwear. And so on…
Our Reaction Is the Real Security Failure
In the headlong rush to “fix” security after the Underwear Bomber’s unsuccessful Christmas Day attack, there’s far too little discussion about what worked and what didn’t, and what will and will not make us safer in the future.
The security checkpoints worked. Because we screen for obvious bombs, Umar Farouk Abdulmutallab—or, more precisely, whoever built the bomb—had to construct a far less reliable bomb than he would have otherwise. Instead of using a timer or a plunger or a reliable detonation mechanism, as would any commercial user of PETN, he had to resort to an ad hoc and much more inefficient homebrew mechanism: one involving a syringe and 20 minutes in the lavatory and we don’t know exactly what else. And it didn’t work…
