It's not just terrorism; it's any rare risk in the news. The big fear in Canada right now, following a particularly gruesome incident, is random decapitations on intercity buses. In the US, fears of school shootings are much greater than the actual risks. In the UK, it's child predators. And people all over the world mistakenly fear flying more than driving. But the very definition of news is something that hardly ever happens. If an incident is in the news, we shouldn't worry about it. It's when something is so common that its no longer news - car crashes, domestic violence - that we should worry. But that's not the way people think.

Psychologically, this makes sense. We are a species of storytellers. We have good imaginations and we respond more emotionally to stories than to data. We also judge the probability of something by how easy it is to imagine, so stories that are in the news feel more probable - and ominous - than stories that are not. As a result, we overreact to the rare risks we hear stories about, and fear specific plots more than general threats.

The problem with building security around specific targets and tactics is that its only effective if we happen to guess the plot correctly. If we spend billions defending the Underground and terrorists bomb a school instead, we've wasted our money. If we focus on the World Cup and terrorists attack Wimbledon, we've wasted our money.

It's this fetish-like focus on tactics that results in the security follies at airports. We ban guns and knives, and terrorists use box-cutters. We take away box-cutters and corkscrews, so they put explosives in their shoes. We screen shoes, so they use liquids. We take away liquids, and they're going to do something else. Or they'll ignore airplanes entirely and attack a school, church, theatre, stadium, shopping mall, airport terminal outside the security area, or any of the other places where people pack together tightly.

These are stupid games, so let's stop playing. Some high-profile targets deserve special attention and some tactics are worse than others. Airplanes are particularly important targets because they are national symbols and because a small bomb can kill everyone aboard. Seats of government are also symbolic, and therefore attractive, targets. But targets and tactics are interchangeable.

The following three things are true about terrorism. One, the number of potential terrorist targets is infinite. Two, the odds of the terrorists going after any one target is zero. And three, the cost to the terrorist of switching targets is zero.

We need to defend against the broad threat of terrorism, not against specific movie plots. Security is most effective when it doesn't require us to guess. We need to focus resources on intelligence and investigation: identifying terrorists, cutting off their funding and stopping them regardless of what their plans are. We need to focus resources on emergency response: lessening the impact of a terrorist attack, regardless of what it is. And we need to face the geopolitical consequences of our foreign policy.

In 2006, UK police arrested the liquid bombers not through diligent airport security, but through intelligence and investigation. It didn't matter what the bombers' target was. It didn't matter what their tactic was. They would have been arrested regardless. That's smart security. Now we confiscate liquids at airports, just in case another group happens to attack the exact same target in exactly the same way. That's just illogical.

This essay originally appeared in The Guardian. Nothing I haven't already said elsewhere.

It's unclear if this error is random or systemic. If it's random -- a small percentage of all votes are dropped -- then it is highly unlikely that this affected the outcome of any election. If it's systemic -- a small percentage of votes for a particular candidate are dropped -- then it is much more problematic.

Ohio is trying to sue:

Ohio Secretary of State Jennifer Brunner is seeking to recover millions of dollars her state spent on the touch-screen machines and is urging the state legislature to require optical scanners statewide instead.

In a lawsuit, Brunner charged on Aug. 6 that touch-screen machines made by the former Diebold Election Systems and bought by 11 Ohio counties "produce computer stoppages" or delays and are vulnerable to "hacking, tampering and other attacks." In all, 44 Ohio counties spent $83 million in 2006 on Diebold's touch screens.

In other news, election officials sometimes take voting machines home for the night.

My 2004 essay: "Why Election Technology is Hard."

I was just reminded of this randomly just by reading this list of new tools released at the Defcon this year. Sounds like a busy conference, with a lot of hackers who love what they do. Good stuff.

It has become more like a global fair than what most people think of conferences; even the badge is highly unique. I say this because there are so many things to do at DEFCON, other than going to talks, that you could spend your whole weekend looking at the “World’s Largest Boar!” so to speak. One of the CTF (Capture the Flag) contest winners this year actually exclaimed that he only made it to 2 talks in 12 years! I am also one of those individuals who barely get a chance to go to talks and now that the speaker pool is so diverse it’s hard to find all of the “stuff” they release.

Same applies to the "primary weapon" of a modern TV war: "evidence of atrocities of the opposing side."

What's the truth? Who knows... progress brought us "TV wars,"  is this the first "YouTube war"? But if we cannot believe the media coverage, how can we believe a random video online? Well ...  maybe the same way we often believe Wikipedia over Britannica. 

In any case, if there was a better time to turn off the TV (and tune off the web news...), it would be now. Also, time to get the dust off my copy of Toffler?

Rant mode off :-)

In particular, SSL certificates (as used to identify https websites) might contain one of these weak keys — and so it would be possible for an attacker to successfully impersonate a secure website. Of course the attacker would need to persuade you to mistakenly visit their site — but it just so happens that one of the more devastating attacks on DNS has recently been discovered; so that’s not as unlikely as it must have seemed back in May.

Anyway, my old friend Ben Laurie (who is with Google these days) and I have been trawling the Internet to determine how many certificates there are containing these weak keys — and there’s a lot: around 1.5% of the certs we’ve examined.

But more of that another day! because earlier this week, Ben spotted that one of the weak certs was for Sun’s “OpenID” website, and that two more OpenID sites were weak as well (by weak we mean that a database lookup could reveal the private key!)

OpenID, for those who are unfamiliar with it, is a scheme for allowing you to prove your identity to site A (viz: provide your user name and password) and then use that identity on site B. There’s a queue of people offering the first bit, but rather less offering the second : because it means you rely on someone else’s due diligence in knowing who their users are — where “who” is a hard sort of thing to get your head around in an online environment.

The problem that Ben and I have identified (advisory here), is that an attacker can poison a DNS cache so it serves up the wrong IP address for openid.sun.com. Then, even if the victim is really cautious and uses https and checks the cert, their credentials can be phished. Thereafter, anyone who trusts Sun as an identity provider could be very disappointed. There’s other attacks as well, but you’ve probably got the general idea by now.

In principle Sun should make a replacement certificate and that should be it (and so they have — read Robin Wilton’s comments here). Except that they need to put the old certificate onto a Certificate Revocation List (CRL) because otherwise it will still be trusted from now until it expires (a fair while off). Sadly, many web browsers, and most of the OpenID codebases haven’t bothered with CRLs (or they don’t enable their checking by default so it’s as if it wasn’t there for most users).

One has to conclude that Sun (and the other two providers) should not be trusted by anyone for quite a while to come. But does that matter ? Since OpenID didn’t promise all that much anyway, does a serious flaw (which does require a certain amount of work to construct an attack) make any difference? At present this looks like the modern equivalent of a small earthquake in Chile.

At any rate, legit torrents of the video presentations are available from The Last HOPE Video Tracker. Art of Information Security is seeding torrents, and plans to do so for the next 10 days.

Check ‘em out.

Cheers, Erik
