Google-Sponsored Study Touts Chrome Security

A Google-commissioned study has come to the conclusion that Google Chrome is, or was at the point in time when tests were conducted, "the Web browser that is most secured against attack."
Accuvant Labs, at Google's behest, compared Mozilla Firefox, Google Chrome, and Microsoft Internet Explorer. Rather than looking at vulnerability report counts and URL blacklists as ways to measure browser security, the company focused on account security architecture and anti-exploitation technology.
"[W]hile Google funded the research for this paper, Accuvant Labs was given a clear directive to provide readers with an objective understanding of relative browser security," the security company says in its report.
Researcher Joshua Drake said in an email that Apple's Safari browser wasn't included because the study focused on the most widely used browsers today, citing statistics compiled by W3schools.com.
The versions tested were Chrome 12 and 13, Firefox 5.0.1, and Internet Explorer 9; tests were conducted in July, 2011, and do not reflect changes made since then.
Chrome, Firefox, and Internet Explorer each implement forms of anti-exploitation technology, but Accuvant suggests Chrome's protection methods are more complete than those used by the other two browser vendors. The firm says that Firefox falls short because doesn't yet support JIT hardening.
JIT (just-in-time) engines in Web browsers take code that has to be interpreted, like JavaScript, and converts it in memory to native binary code for execution. When this code produces predictable patterns, an attacker may be able to identify those patterns and alter the code maliciously. JIT hardening provides a way to mitigate such threats.
As for Internet Explorer, Accuvant suggests that its plug-in security and sandboxing architecture are less comprehensive than Chrome's.
Google is understandably pleased about Accuvant's findings. "We built Chrome with security as one of the core tenets and continue to work actively with the top minds in the security community," a company spokesperson said in an emailed statement. "We believe that many of the security approaches we've integrated into Chrome help to set it apart."
Johnathan Nightingale, Mozilla's director of Firefox engineering, meanwhile says his company is proud of its reputation for security and that security remains a central priority for Firefox. "Firefox includes a broad array of technologies to eliminate or reduce security threats, from platform-level features like address space randomization to internal systems like our layout frame poisoning system," he said in an email. "Sandboxing is a useful addition to that toolbox that we are investigating, but no technology is a silver bullet. We invest in security throughout the development process with internal and external code reviews, constant testing and analysis of running code, and rapid response to security issues when they emerge."
Microsoft didn't immediately respond to a request for comment.
