Automatic Profiling Is Useless

No surprise:

Automated passenger profiling is rubbish, the Home Office has conceded in an amusing—and we presume inadvertent—blurt. “Attempts at automated profiling have been used in trial operations [at UK ports of entry] and has proved [sic] that the systems and technology available are of limited use,” says home secretary Jacqui Smith in her response to Lord Carlile’s latest terror legislation review.

The U.S. wants to do it anyway:

The Justice Department is considering letting the FBI investigate Americans without any evidence of wrongdoing, relying instead on a terrorist profile that could single out Muslims, Arabs or other racial or ethnic groups.

I’ve written about profiling before.

The War on T-Shirts

London Heathrow security stopped someone from boarding a plane for wearing a Transformers T-shirt showing a cartoon gun.

It’s easy to laugh and move on. How stupid can these people be, we wonder. But there’s a more important security lesson here. Security screening is hard, and every false threat the screeners watch out for make it more likely that real threats slip through. At a party the other night, someone told me about the time he accidentally brought a large knife through airport security. The screener pulled his bag aside, searched it, and pulled out a water bottle.

It’s not just the water bottles and the t-shirts and the gun jewelry—this kind of thing actually makes us all less safe.

Bletchley Park May Close Due to Lack of Funds

Sad.

But, despite an impressive contribution to the war effort, the Bletchley Park site, now a museum, faces a bleak future unless it can secure funding to keep its doors open and its numerous exhibits from rotting away.

The Bletchley Park Trust receives no external funding. It has been deemed ineligible for funding by the National Lottery, and turned down by the Bill & Melinda Gates Foundation because the Microsoft founder will only fund internet-based technology projects.

“We are just about surviving. Money—or lack of it—is our big problem here. I think we have two to three more years of survival, but we need this time to find a solution to this,” said Simon Greenish, the Trust’s director.

As a result of lack of funds, the Trust is unable to rebuild the site’s rotting infrastructure and faces an uncertain future. “The Trust is the hardest-up museum I know,” said Greenish. “We have this huge estate to run and it’s one of the most important World War II stories there is.”

Anybody out there want to help put together a major contribution?

EDITED TO ADD (5/30): Yes, I am willing to be a focal point for donations. But I’m hoping for some major donors.

EDITED TO ADD (6/13): Donate here.

Crossing Borders with Laptops and PDAs

Last month a US court ruled that border agents can search your laptop, or any other electronic device, when you’re entering the country. They can take your computer and download its entire contents, or keep it for several days. Customs and Border Patrol has not published any rules regarding this practice, and I and others have written a letter to Congress urging it to investigate and regulate this practice.

But the US is not alone. British customs agents search laptops for pornography. And there are reports on the internet of this sort of thing happening at other borders, too. You might not like it, but it’s a fact. So how do you protect yourself?

Encrypting your entire hard drive, something you should certainly do for security in case your computer is lost or stolen, won’t work here. The border agent is likely to start this whole process with a “please type in your password”. Of course you can refuse, but the agent can search you further, detain you longer, refuse you entry into the country and otherwise ruin your day.

You’re going to have to hide your data. Set a portion of your hard drive to be encrypted with a different key – even if you also encrypt your entire hard drive – and keep your sensitive data there. Lots of programs allow you to do this. I use PGP Disk . TrueCrypt is also good, and free.

While customs agents might poke around on your laptop, they’re unlikely to find the encrypted partition. (You can make the icon invisible, for some added protection.) And if they download the contents of your hard drive to examine later, you won’t care.

Be sure to choose a strong encryption password. Details are too complicated for a quick tip, but basically anything easy to remember is easy to guess. (My advice is here.) Unfortunately, this isn’t a perfect solution. Your computer might have left a copy of the password on the disk somewhere, and (as I also describe at the above link) smart forensic software will find it.

So your best defence is to clean up your laptop. A customs agent can’t read what you don’t have. You don’t need five years’ worth of email and client data. You don’t need your old love letters and those photos (you know the ones I’m talking about). Delete everything you don’t absolutely need. And use a secure file erasure program to do it. While you’re at it, delete your browser’s cookies, cache and browsing history. It’s nobody’s business what websites you’ve visited. And turn your computer off – don’t just put it to sleep – before you go through customs; that deletes other things. Think of all this as the last thing to do before you stow your electronic devices for landing. Some companies now give their employees forensically clean laptops for travel, and have them download any sensitive data over a virtual private network once they’ve entered the country. They send any work back the same way, and delete everything again before crossing the border to go home. This is a good idea if you can do it.

If you can’t, consider putting your sensitive data on a USB drive or even a camera memory card: even 16GB cards are reasonably priced these days. Encrypt it, of course, because it’s easy to lose something that small. Slip it in your pocket, and it’s likely to remain unnoticed even if the customs agent pokes through your laptop. If someone does discover it, you can try saying: “I don’t know what’s on there. My boss told me to give it to the head of the New York office.” If you’ve chosen a strong encryption password, you won’t care if he confiscates it.

Lastly, don’t forget your phone and PDA. Customs agents can search those too: emails, your phone book, your calendar. Unfortunately, there’s nothing you can do here except delete things.

I know this all sounds like work, and that it’s easier to just ignore everything here and hope you don’t get searched. Today, the odds are in your favour. But new forensic tools are making automatic searches easier and easier, and the recent US court ruling is likely to embolden other countries. It’s better to be safe than sorry.

This essay originally appeared in The Guardian.

Some other advice here.

EDITED TO ADD (5/18): Many people have pointed out to me that I advise people to lie to a government agent. That is, of course, illegal in the U.S. and probably most other countries—and probably not the best advice for me to be on record as giving. So be sure you clear your story first with both your boss and the New York office.

Cell Phone Spying

A handy guide:

A service called World Tracker lets you use data from cell phone towers and GPS systems to pinpoint anyone’s exact whereabouts, any time—as long as they’ve got their phone on them.

All you have to do is log on to the web site and enter the target phone number. The site sends a single text message to the phone that requires one response for confirmation. Once the response is sent, you are locked in to their location and can track them step-by-step. The response is only required the first time the phone is contacted, so you can imagine how easily it could be handled without the phone’s owner even knowing.

Once connected, the service shows you the exact location of the phone by the minute, conveniently pinpointed on a Google Map. So far, the service is only available in the UK, but the company has indicated plans to expand its service to other countries soon.

[…]

Dozens of programs are available that’ll turn any cell phone into a high-tech, long-range listening device. And the scariest part? They run virtually undetectable to the average eye.

Take, for example, Flexispy. The service promises to let you “catch cheating wives or cheating husbands” and even “bug meeting rooms.” Its tools use a phone’s microphone to let you hear essentially any conversations within earshot. Once the program is installed, all you have to do is dial a number to tap into the phone’s mic and hear everything going on. The phone won’t even ring, and its owner will have no idea you are virtually there at his side.

Al Qaeda Threat Overrated

Seems obvious to me:

“I reject the notion that Al Qaeda is waiting for ‘the big one’ or holding back an attack,” Sheehan writes. “A terrorist cell capable of attacking doesn’t sit and wait for some more opportune moment. It’s not their style, nor is it in the best interest of their operational security. Delaying an attack gives law enforcement more time to detect a plot or penetrate the organization.”

Terrorism is not about standing armies, mass movements, riots in the streets or even palace coups. It’s about tiny groups that want to make a big bang. So you keep tracking cells and potential cells, and when you find them you destroy them. After Spanish police cornered leading members of the group that attacked trains in Madrid in 2004, they blew themselves up. The threat in Spain declined dramatically.

Indonesia is another case Sheehan and I talked about. Several high-profile associates of bin Laden were nailed there in the two years after 9/11, then sent off to secret CIA prisons for interrogation. The suspects are now at Guantánamo. But suicide bombings continued until police using forensic evidence—pieces of car bombs and pieces of the suicide bombers—tracked down Dr. Azahari bin Husin, “the Demolition Man,” and the little group around him. In a November 2005 shootout the cops killed Dr. Azahari and crushed his cell. After that such attacks in Indonesia stopped.

The drive to obliterate the remaining hives of Al Qaeda training activity along the Afghanistan-Pakistan frontier and those that developed in some corners of Iraq after the U.S. invasion in 2003 needs to continue, says Sheehan. It’s especially important to keep wanna-be jihadists in the West from joining with more experienced fighters who can give them hands-on weapons and explosives training. When left to their own devices, as it were, most homegrown terrorists can’t cut it. For example, on July 7, 2005, four bombers blew themselves up on public transport in London, killing 56 people. Two of those bombers had trained in Pakistan. Another cell tried to do the same thing two weeks later, but its members had less foreign training, or none. All the bombs were duds.

[…]

Sir David Omand, who used to head Britain’s version of the National Security Agency and oversaw its entire intelligence establishment from the Cabinet Office earlier this decade, described terrorism as “one corner” of the global security threat posed by weapons proliferation and political instability. That in turn is only one of three major dangers facing the world over the next few years. The others are the deteriorating environment and a meltdown of the global economy. Putting terrorism in perspective, said Sir David, “leads naturally to a risk management approach, which is very different from what we’ve heard from Washington these last few years, which is to ‘eliminate the threat’.”

Yet when I asked the panelists at the forum if Al Qaeda has been overrated, suggesting as Sheehan does that most of its recruits are bunglers, all shook their heads. Nobody wants to say such a thing on the record, in case there’s another attack tomorrow and their remarks get quoted back to them.

That’s part of what makes Sheehan so refreshing. He knows there’s a big risk that he’ll be misinterpreted; he’ll be called soft on terror by ass-covering bureaucrats, breathless reporters and fear-peddling politicians. And yet he charges ahead. He expects another attack sometime, somewhere. He hopes it won’t be made to seem more apocalyptic than it is. “Don’t overhype it, because that’s what Al Qaeda wants you to do. Terrorism is about psychology.” In the meantime, said Sheehan, finishing his fruit juice, “the relentless 24/7 job for people like me is to find and crush those guys.”

I’ve ordered Sheehan’s book, Crush the Cell: How to Defeat Terrorism Without Terrorizing Ourselves.
