CESG, the UK government's arm that assesses operating systems and software security, has published its findings for ‘End User Device’ operating systems. The most secure of the lot? Ubuntu 12.04. For the full article see here

Thank you for the information it was interesting reading. It is nice to have someone validate what has been said by those of us who have been promoting the security of Linux based systems for years (and I include you in that number Jim).

You might note that although they evaulated at two versions of The Andriod OS, two blackberry, two Apple OS and three Windows based the only version of Linux they reviewed was Ubuntu. It is possible that this is the only linux distro besides Fedora, that specifically has a version to run on mobile devices. And that Fedora 20 was just recently released probably too late to be considered.
