QubesOS
Qubes OS is a security-focused operating system, security-focused desktop operating system that aims to provide computer security, security through isolation. Isolation is provided through the use of virtualization technology. This allows the segmentation of applications into secure virtual machines called qubes. Virtualization services in Qubes OS are provided by the Xen hypervisor. The runtimes of individual qubes are generally based on a unique system of underlying operating system ''templates''. Templates provide a single, immutable root file system which can be shared by multiple qubes. This approach has two major benefits. First, updates to a given template are automatically "inherited" by all qubes based on it. Second, shared templates can dramatically reduce storage requirements compared to separate VMs with a full operating install per secure domain. The base installation of Qubes OS provides a number of officially supported templates based on the Fedora (operating s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xfce
Xfce or XFCE (pronounced as four individual letters, ) is a Free and open-source software, free and open-source desktop environment for Linux and other Unix-like operating systems. Xfce aims to be fast and Lightweight software, lightweight while still visually appealing and easy to use. The desktop environment is designed to embody the traditional Unix philosophy of Modular programming, modularity and re-usability, as well as adherence to standards; specifically, those defined at freedesktop.org. Features User experience Xfce is a highly modular desktop environment, with many software repositories separating its components into multiple packages. The built-in settings app offers options to customize the GTK theme, the system Icon (computing), icons, the Cursor (computing), cursor, and the window manager. Additionally, Xfce provides a fully GUI-based system for modifying the desktop's status bar and system tray. Performance Xfce is a lightweight desktop environment which o ...

Joanna Rutkowska
Joanna Rutkowska (born 1981 in Warsaw) is a Polish computer security researcher, primarily known for her research on low-level security and stealth malware, and as founder of the Qubes OS security-focused desktop operating system. Career She became known in the security community after the Black Hat Briefings conference in Las Vegas in August 2006, where Rutkowska presented an attack against Windows Vista, Vista kernel (operating system), kernel protection mechanism, and also a technique dubbed Blue Pill (software), Blue Pill, that used hardware virtualization to move a running Operating system, OS into a virtual machine. Subsequently, she has been named one of ''Five Hackers who Put a Mark on 2006'' by eWeek, eWeek Magazine for her research on the topic. The original concept of Blue Pill was published by another researcher at IEEE Oakland in May 2006 under the name VMBR. During the following years, Rutkowska continued to focus on low-level security. In 2007 she demonstrated tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
