QUBES OS: THE JUNCTION BETWEEN THE VIRTUALIZATION, SECURITY AND OPEN SOURCE

By -

It is this complexity that are looking grim now teams Invisible Things Lab , led by Joanna Rutkowska, which works since 2004 as CEO.In a blog post , the applicant refers to the need for simplification of Qubes OS, yet austere rudiments that has zero IT security.And play with modesty in mind that this first final version (1.0, available as an ISO image ) does not in any way constitute a bulwark against tight security threats, whether malicious files or attacks.

Invisible Things Lab but made it a point of honor to secure the foundations of the system, including the kernel.Several bugs have been eradications consecutive at the option of multiple tests.

There is no question of graphics acceleration in virtual machines, but ultimately, the interaction with the Windows ecosystem is self-evident.
