According to this eWeek article, Google has just bought Internet security startup GreenBorder Technologies Inc.
Here’s an excerpt from the article:
GreenBorder, a venture-backed startup founded in 2001 and based in Mountain View, California, where Google is also headquartered, offers security software that sets up temporary, virtual sessions each time a computer users surfs the Web, then discards the resulting data once the user is finished surfing.
The article then goes on to describe the technology:
The technology creates a secure zone, called a sandbox, for online interaction. "Any type of activity and interaction, while you are on the Internet, will be directed to the protected environment," according to GreenBorder's site.
Out of the many ways to protect end users from malware, viruses and other types of malicious content, I am a strong supporter of this specific positive approach, and am very surprised (and saddened) to see that desktop anti-virus vendors have mostly decided to disregard this approach, and stick mainly to negative (signature-based) solutions.
