Linux Top 3: Pentoo, Linux Mint 17.1 KDE and openSUSE Tumbleweed Security
1) Pentoo 3.7
There is no shortage of security focussed Linux distributions and you can add Pentoo to that list. Unlike many of the others that typically use some manner of Debian based system as a base, Pentoo is based on Gentoo Linux. So instead of RPM, or a .deb based system, Pentoo leverages the Gentoo Porage system for package management.
Among the key enhancements in Pentoo 3.7 is the ability to more easily verify the integrity of the download Pentoo ISO.
"The boot menu has a new "verify" option which will confirm that the iso files have not been corrupted by unetbootin or a bad thumb drive," Pentoo's 3.7 release announcement states. "I know checking md5sums yourself is annoying, plus it's impossible to verify after you install to a thumb drive, so now you can do it quickly on boot, automatically."
Additionally with Pentoo 3.7, Ruby 2.1 is included which apparently makes a big performance difference for Metasploit.
"This change was not only important because ruby 1.9 support is ending soon, but because it was a near 600% increase in speed. Remember waiting 30+ seconds for msfconsole to load? Well, those days are gone."
2) Linux Mint 17.1 KDE/
Linux Mint 17.1 first came out at the end of 2014, but with *only* the Cinnamon and MATE desktop environments. Now at long last Clem and his development team have put out new milestones for the KDE 4.14 desktop
Support was added in MDM and in the session for the KDE wallet to be fully integrated with Linux Mint.
Although a Wallet Manager is present for configuration purpose, no interaction is needed for the KDE wallet to work.
3) openSUSE Tumbleweed security
While openSUSE still has milestone releases, it's Tumbleweed rolling release has continued to …roll along. One of the latest openSUSE Tumbleweed snapshots is 20150105 and it provides some interesting new security capabilities for users.
"AppArmor updated to version 2.9.1 and has numerous improvements and bug fixes made to python tools. It has a fix log parsing for 3.16 kernels and syslog-style logs."
