Joanna Rutkowska is a security researcher. She invented the malware application Blue Pill. Now she’s released a secure open source Linux operating system called Qubes.
According to the Qubes Web sites it implements security by isolation.
“To do this, Qubes utilizes virtualization technology, to be able to isolate various programs from each other, and even sandbox many system-level components, like networking or storage subsystem, so that their compromise don’t affect the integrity of the rest of the system.”
Qubes is currently in the alpha stage, but Rutkowska said that she’s been running it as her primary system for a month now.
“I use Qubes for pretty much all the other daily tasks, from work, shopping, banking, random browsing, to Qubes development itself,” she said.
