Today, you can find more online security tips in a few seconds than you could use in a lifetime. While this collection of best practices is rich, it’s not always useful; it can be difficult to know which ones to prioritize, and why.

Questions like ‘Why do people make some security choices (and not others)?’ and ‘How effectively does the security community communicate its best practices?’ are at the heart of a new paper called, “...no one can hack my mind”: Comparing Expert and Non-Expert Security Practices” that we’ll present this week at the Symposium on Usable Privacy and Security.

This paper outlines the results of two surveys—one with 231 security experts, and another with 294 web-users who aren’t security experts—in which we asked both groups what they do to stay safe online. We wanted to compare and contrast responses from the two groups, and better understand differences and why they may exist.

Experts’ and non-experts’ top 5 security practices

Here are experts’ and non-experts’ top security practices, according to our study. We asked each participant to list 3 practices:
Common ground: careful password management

Clearly, careful password management is a priority for both groups. But, they differ on their approaches.

Security experts rely heavily on password managers, services that store and protect all of a user’s passwords in one place. Experts reported using password managers, for at least some of their accounts, three-times more frequently than non-experts.

As one expert said, “Password managers change the whole calculus because they make it possible to have both strong and unique passwords.”

On the other hand, only 24% of non-experts reported using password managers for at least some of their accounts, compared to 73% of experts. Our findings suggested this was due to lack of education about the benefits of password managers and/or a perceived lack of trust in these programs. “I try to remember my passwords because no one can hack my mind,” one non-expert told us.


Key differences: software updates and antivirus software

Despite some overlap, experts’ and non-experts’ top answers were remarkably different.

35% of experts and only 2% of non-experts said that installing software updates was one of their top security practices. Experts recognize the benefits of updates—“Patch, patch, patch,” said one expert—while non-experts not only aren’t clear on them, but are concerned about the potential risks of software updates. A non-expert told us: “I don’t know if updating software is always safe. What [if] you download malicious software?” and “Automatic software updates are not safe in my opinion, since it can be abused to update malicious content.”

Meanwhile, 42% of non-experts vs. only 7% of experts said that running antivirus software was one of the top three three things they do to stay safe online. Experts acknowledged the benefits of antivirus software, but expressed concern that it might give users a false sense of security since it’s not a bulletproof solution.


Next Steps

In the immediate term, we encourage everyone to read the full research paper, borrow experts’ top practices, and also check out our tips for keeping your information safe on Google.

More broadly, our findings highlight fundamental misunderstandings about basic online security practices. Software updates, for example, are the seatbelts of online security; they make you safer, period. And yet, many non-experts not only overlook these as a best practice, but also mistakenly worry that software updates are a security risk.

No practice on either list—expert or non-expert—makes users less secure. But, there is clearly room to improve how security best practices are prioritized and communicated to the vast majority of (non expert) users. We’re looking forward to tackling that challenge.

  • Rules are dangerously broad and vague. The proposed rules are not feasible and would require Google to request thousands - maybe even tens of thousands - of export licenses. Since Google operates in many different countries, the controls could cover our communications about software vulnerabilities, including: emails, code review systems, bug tracking systems, instant messages - even some in-person conversations! BIS’ own FAQ states that information about a vulnerability, including its causes, wouldn’t be controlled, but we believe that it sometimes actually could be controlled information.
  • You should never need a license when you report a bug to get it fixed. There should be standing license exceptions for everyone when controlled information is reported back to manufacturers for the purposes of fixing a vulnerability. This would provide protection for security researchers that report vulnerabilities, exploits, or other controlled information to any manufacturer or their agent.
  • Global companies should be able to share information globally. If we have information about intrusion software, we should be able to share that with our engineers, no matter where they physically sit.
  • Clarity is crucial. We acknowledge that we have a team of lawyers here to help us out, but navigating these controls shouldn’t be that complex and confusing. If BIS is going to implement the proposed controls, we recommend providing a simple, visual flowchart for everyone to easily understand when they need a license.
  • These controls should be changed ASAP. The only way to fix the scope of the intrusion software controls is to do it at the annual meeting of Wassenaar Arrangement members in December 2015.

We’re committed to working with BIS to make sure that both white hat security researchers’ interests and Google users’ interests are front of mind. The proposed BIS rule for public comment is available here, and comments can also be sent directly to publiccomments@bis.doc.gov. If BIS publishes another proposed rule on intrusion software, we’ll make sure to come back and update this blog post with details.

Last year, we announced our increased focus on unwanted software (UwS), and published our unwanted software policy. This work is the direct result of our users falling prey to UwS, and how badly it was affecting their browsing experience. Since then, Google Safe Browsing’s ability to detect deceptive software has steadily improved.

In the coming weeks, these detection improvements will become more noticeable in Chrome: users will see more warnings (like the one below) about unwanted software than ever before.

We want to be really clear that Google Safe Browsing’s mandate remains unchanged: we’re exclusively focused on protecting users from malware, phishing, unwanted software, and similar harm. You won’t see Safe Browsing warnings for any other reasons.

Unwanted software is being distributed on web sites via a variety of sources, including ad injectors as well as ad networks lacking strict quality guidelines. In many cases, Safe Browsing within your browser is your last line of defense.

Google Safe Browsing has protected users from phishing and malware since 2006, and from unwanted software since 2014. We provide this protection across browsers (Chrome, Firefox, and Safari) and across platforms (Windows, Mac OS X, Linux, and Android). If you want to help us improve the defenses for everyone using a browser that integrates Safe Browsing, please consider checking the box that appears on all of our warning pages:
Safe Browsing’s focus is solely on protecting people and their data from badness. And nothing else.
