Google details Chrome browser security-testing technology

'ClusterFuzz' is an industrial-strength system the company uses to check for holes in the browser

Since late last year, Google has been using an industrial-strength testing system to identify, analyze and fix security holes in its Chrome browser, helping it significantly cut down on the number of vulnerabilities that slip through to the most recent version product in production.

Google calls the system ClusterFuzz. It's made up of "several hundred" virtual machines loaded with about 6,000 Chrome instances, subjecting them to about 50 million test cases every day, the company said on Thursday.

The system's capacity is projected to quadruple in the coming weeks. Since its full deployment late last year, ClusterFuzz has flagged 95 unique vulnerabilities, 44 of which were fixed before making it into the most recent stable release of the browser, according to a Google blog post.

In addition to benefiting users of the product, the detections also help open-source software used by Chrome like WebKit and FFmpeg, because Google submits vulnerability reports to their project teams.

In addition to running the tests and detecting browser crashes, ClusterFuzz is also used to manage the distribution of test cases, analyze the crashes to determine if they involve a security hole that can be exploited, and verify if a vulnerability has been properly fixed.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
