Schwartz On Security: Don't Get Hacked For the Holidays

The Gawker data breach highlights how few companies employ passwords for security, and how many Web site users treat them as little more than a nuisance.

But what's also fascinating, he said, is that when it comes to poor password selection, "the problem has changed very little over the past 20 years."

In fact, a 1990 study of Unix password selection found quite similar results to Imperva’s study. Of course, the equation since then has changed, as Shulman noted. Get your Gawker password hacked, and if it's the same as your Gmail, Amazon and Facebook passwords, you could be in for embarrassment, if not trouble.

The frequency with which people do reuse passwords was further highlighted, indirectly, by the Gawker attackers. Notably, they publicized their attack by finding Gawker passwords that also allowed them to log into people's Twitter and Facebook accounts, because they’d recycled the same password. Furthermore, Twitter traced at least one spam attack to the stolen Gawker credentials.

Perhaps unrelated Web sites can't force users to choose different passwords, but why don't they at least force users or customers to choose stronger ones?

Well, as the ninth most popular Gawker password highlights, Web site users are first and foremost consumers, and corporate password requirements reflect this. Namely, Web sites don't want to scare away users -- who generate advertising revenue -- or customers.

In fact, passwords are often a marketing Trojan horse, or maybe not even that subtle. According to a paper delivered at the ninth annual Workshop on the Economics of Information Security at Harvard University, passwords are often employed "primarily for psychological reasons, both as a justification for collecting marketing data, and as a way to build trusted relationships with customers." Note that the word "security" is lacking from that equation.

This commercial reality was also highlighted during the Gawker debacle, in internal company communications leaked by attackers. Notably, after Gawker employees determined that their Web site and systems had been exploited and monitored for at least a month, they thought the breach was confined solely to the names of people who'd commented on content. "Just the peasants?" asked Gawker's Richard Lawson. Yes, came the answer. Only, no.

Ironically, one of the best guides to using strong passwords was published four years ago by Lifehacker. The first piece of advice? "Don't use the same password for everything." Perhaps the second should have been: Don't be a peasant.
