Users Rejecting Security Advice Considered Rational

WeeBit writes "Researchers have different ideas as to why people fail to use security measures. Some feel that regardless of what happens, users will only do the minimum required. Others believe security tasks are rejected because users consider them to be a pain. A third group maintains user education is not working. [Microsoft Research's Cormac] Herley offers a different viewpoint. He contends that user rejection of security advice is based entirely on the economics of the process." Here is Dr. Herley's paper, So Long, And No Thanks for the Externalities: The Rational Rejection of Security Advice by Users (PDF).

Their reasoning was not the $50 one time cost but, "who would want to go to the trouble of accessing our data? we have nothing sensitive"

The more warnings you throw at them, the more accustomed they become to rejecting them and eventually they get a mentality where they deny all recommendations and wait for an attack to happen, then learn their lesson for that one attack only.

      In this case, the cost was $50 up front but the indirect cost would be needing to learn how to add new devices to the secured wireless, store yet another password somewhere, possibly change the password as problems occurred: all of which would likely lead to having network outages and having your team come back to fix it when it breaks.

    The paper is not entirely unreasonable. However, there are at least some holes in it.

    It lumps good and bad security advice together. The economic benefit of following bad security advice (e.g., buying antivirus software) is zero or negative, so of course anybody would be rational to ignore such advice. That doesn't mean it should be lumped together with *good* security advice. They're hypothesizing that people are acting like the idealized economic free agents beloved of economists: people with perfect information, acting rationally. Under this hypothesis, people would have perfect information about which security advice is good and which is bad.

    The article doesn't talk about costs to others. People who get their computers owned by a botnet aren't only suffering economic harm themselves, they're inflicting harm on other people. On p. 5 Herley talks about how Wells Fargo limits customers' liability to $50 if they're victims of fraud. That doesn't mean *nobody* pays the cost of the fraud. We all pay those costs, indirectly.

    Another problem is that in many cases Herley relies on back-of-the-envelope estimates of the damage caused by security failures. E.g., on p. 2 he estimates the economic costs of a particular exploit. But these estimates aren't based on any actual data. That particular calculation is also kind of stupid, because he says that a user shouldn't spend more than "0.98 seconds" (doesn't he understand significant figures?) protecting against a particular exploit. What his analysis ignores is that there may be hundreds of such exploits out there, and that anything you do that protects against one exploit (e.g., not using a dictionary word as your password) will also help to protect you against all the others. And forgive me if I'm a little skeptical of low-ball estimates originating from MS of the economic damage of computer security failures. That's like trusting GM to estimate the economic effects of global warming.

    It's obvious that most computer security practices are the equivalent of cracking the metaphorical nut with a sledgehammer. My personal pet hate is the password aging practice. It specifically does one of two things. It discourages people from choosing strong passwords because strong passwords are more difficult to create and remember than weak ones. The second is that users may resort to writing passwords down because some expert decided they needed to change their password every 30 days. And often you get thet password change prompt right when you are about to go on a long holiday, which guarantees that you will not be able to remember it

    One reason for this is that organisations have to show that they are serious about security, and practices like password aging are easy 'objective' metrics to demonstrate, even if they do not provide a measurable improvement in security.

    1. Re:It's obvious by knarfling · · Score: 3, Informative
      A tough question, especially since "best practice" dictates that the password be changed often. I did a little research into this and found that UNIX is actually the culprit for needing to change passwords often.

      It seems that several year ago, the /etc/passwd file was world readable (since it had to be read in order to log in), and that both the username and password was stored there. (Now the passwords are stored in /etc/shadow which is not world readable.) It was fairly simple for someone to download a passwd file and then run it through a dictionary cracker to find the passwords. In the early 80's it was found that a dedicated mainframe could crack any dictionary word in the passwd file in about eight weeks. If the hacker only had access for a couple hours a day, it could take up to four months. (If a complex password was used, it would take much longer or possibly never be cracked.) Therefore, if a person changed his password every 30 days, he could be sure that by the time the hacker cracked his password, it had been changed.

      However, as computers became more powerful, the time to crack passwords from a passwd file became less and less, a better solution needed to be found. One method was to separate the password from the username into a shadow file, and make sure that the shadow file was not world readable. A cracker would need to break into the computer with root privileges in order to read the password file so that they could break into the computer.

      Unfortunately, the above explanation is long, complicated, and goes against "best practices." I have tried pointing that out to several "Security experts" without any success. Pointing out that passwords will be written down if they have to be changed often will not help much either.

    For some time, I've encouraged taking a harder line on phishing-friendly sites, sites that host phishing pages. I had a paper on this at the 2008 MIT Spam Conference. At SiteTruth, we take the position that one phishing page blacklists the whole second-level domain. Here's the current list of major domains being exploited by active phishing scams.

    The free hosting sites and the "short URL" sites show up on the blacklist regularly. After much nagging and some press coverage, most of them are now very aggressive about kicking off phishing pages, and they don't stay on for long. The better ones now read PhishTank and the APWG blacklist automatically and kick off anything that shows up. Currently, Google is in the doghouse, because they've recently entered the "free hosting business" without adequate phishing defenses. See this abuse of Google Spreadsheets.

    At the moment, "t35.com", a free hosting service, is the site most abused in this way, by a large margin. I've contacted their people. The problem is that they're being attacked by a program, and they're cleaning up by hand. Right now, they're hosting 545 known phishing pages. Nobody else is even in double digits. "piczo.com" (a social network/free hosting service for teenage girls) was the last big victim, but they're gradually getting the problem under control.

    A Draconian blacklisting policy may seem harsh, but it encourages site operators of easily-exploited sites to be very aggressive about dealing with the problem. We're seeing more free hosting sites with a "click here if this is abuse" button on every page. The number of people who have to be educated to deal with the problem in this way is in the hundreds, not the hundreds of millions. So it's a solveable problem.

    If you're going to blame the victim, this is the way to go at it.
