Tool kit for building highly secure special-purpose operating systems
The Genode OS Framework is a tool kit for building highly secure special-purpose operating systems. It scales from embedded systems with as little as 4 MB of memory to highly dynamic general-purpose workloads. Genode is based on a recursive system structure. Each program runs in a dedicated sandbox and gets granted only those access rights and resources that are needed for its specific purpose. Programs can create and manage sub-sandboxes out of their own resources, thereby forming hierarchies where policies can be applied at each level. The framework provides mechanisms to let programs communicate with each other and trade their resources, but only in strictly-defined manners. Thanks to this rigid regime, the attack surface of security-critical functions can be reduced by orders of magnitude compared to contemporary operating systems.
exGENT Live DVD is - as the name suggests - based on Gentoo Linux
exGENT version 170412/170407 Linux Live DVD's are - as the name suggests - based on Gentoo Linux. The best thing with exGENT is the premier auto detection of hardware and the ability to relatively easily install the system to hard drive during a live session. Xfce 4.12.1 and LXQt 0.11.0 are used as Desktop environments. Used kernel: 4.10.4. INSTALLATION The systems can easily be installed to hard drive and/or a USB flash drive. The installation takes 3 - 10 min. (Depending on computer type). ROLLING DISTRIBUTION Gentoo/exGENT is a "rolling" distribution, which means that you can always get the latest software without reinstalling. GO FOR IT! You'll run exGENT super fast in RAM. The launch from the DVD becomes a little slow, but then... A wonderful way to run Linux if you have enough RAM. You'll need at least 3 GB. SPOTIFY Just emerge it! (Pre-installed in both builds). WHO IS exGENT/Gentoo FOR? Experienced Linux users or those who really want to learn Linux.
