Home-computer users at risk due to use of 'folk model' security

(PhysOrg.com) -- Most home computers are vulnerable to hacker attacks because the users either mistakenly think they have enough security in place or they don’t believe they have enough valuable information that would be of interest to a hacker.

That’s the point of a paper published this month by Michigan State University’s Rick Wash, who says that most home-computer users rely on what are known as “folk models.” Those are beliefs about what hackers or viruses are that people use to make decisions about security – to keep their information safe.

Unfortunately, they don’t often work the way they should.

“Home security is hard because people are untrained in security,” said Wash, an assistant professor in the Department of Telecommunication, Information Studies and Media. “But it isn’t because people are idiots. Rather they try their best to make sense of what’s going on and frequently make choices that leave them vulnerable.”

In his paper, published in the proceedings of the Symposium on Usable Privacy and Security, Wash identified eight folk models of security threats that are used by home to decide what security software to use and which advice to follow.

These models range from the vague and generic – “viruses are bad” – to the more specific – “hackers are burglars who break into computers for criminal purposes.”

Adding to the problem, Wash said, is that people who rely on folk models for computer security don’t necessarily follow security advice from credible experts. This is because they either don’t understand the advice or because they believe the security advice isn’t relevant to them.

Knowing what people believe or discount can help the experts help the users.

“The folk models we describe begin to provide an explanation of which expert advice home computer users choose to follow and which advice to ignore,” Wash said. “By better understanding why people choose to ignore certain pieces of advice, we can better craft that advice and technologies to have a greater effect.”

It’s also important, he said, that security experts do a better job of explaining the threats that home computer users face.

“Without an understanding of threats, home-computer users intentionally choose to ignore advice that they don’t believe will help them,” Wash said. “ education efforts should focus not only on recommending what actions to take, but also emphasize why those actions are necessary.”

So.... what exactly was the point of this article?

Stookified good point.

get linux.

From the paper, "Everyone who had a Mac seemed to believe that Macs are `immune' to virus and hacking problems." You seem to suffer from a similar delusion.

All the experts offering advice are trying to sell a product! I tend to ignore such people. I read the reviews and make a decision based on flash-bang-clutter removal then look at what's left. Above all, I avoid Best Buy.

While Linux might become the target of a large, successful attack, as of yet it has not been.

Often people will say that Linux is Like Mac because they have small user bases. While the numbers of users of Linux is lower, Linux targets are much more sought after (Most servers are Linux, not Windows or Mac). The gain of being able to compromise a Linux Box is greater than that of Mac.

The Difference between Linux, Mac and Windows is how Security driven they are. There are several Distributions of Linux that focus on security, also the way that Linux is built, maintained and the way the users interact with it, all work to preclude the ability for it to become comprimised.

Windows security is difficult because of all the Extras windows activates, and places in their system "Just in case" you want to use them. These are all vectors for attack.

Mac Security is Difficult because of the "Black Box" Nature of Apple. It is difficult to secure a Mac system, because you have to trust apple.

Linux security is much stronger because of the ease of application of security (Most linux distributions start out pretty secure, and it is a simple matter to make them fort knox secure). It is also much eaiser to have a secure linux system because of the way that Linux handles programs, updates, passwords, etc.

So, while, yes a linux distribution may some day become the target of an actual Virus, or other piece of malware, the likely hood of someone compliling the software to run it (in the process putting in their admin password several times, being warned about bad software etc) then after compiling the software for their system, giving it the permission to act as admin, then run the software as admin... It's kinda low.

Certainly not like the vectors for Windows or Mac when going to a website or viewing an e-mail could infect you.
