As part of its Information Mission (http://www.nsa.gov/ia/index.cfm), the National Security Agency has long been involved with the computer security research community in investigating a wide range of computer security topics including operating system security. Recognizing the critical role of operating system security mechanisms in supporting security at higher levels, researchers from NSA's Information Assurance Research Group have been investigating an architecture that can provide the necessary security functionality in a manner that can meet the security needs of a wide range of computing environments.
SELinux (Security-enhanced Linux) in Fedora Core is an implementation of Mandatory Access Control (MAC) in the Linux kernel. Standard Linux security is a Discretionary Access Control (DAC) model, where super-user accounts have complete (discretionary) control over every aspect of the system. Compromise of a superuser gives an attacker total control. In a DAC system, some applications need super-user privileges to perform their functions. By contrast, a MAC system provides granular permissions for all users, programs, processes, files and devices. You can safely grant an application just the permissions it needs to do its function, and no more.
The goal of the Fedora Project is to work with the Linux community to build a complete, general purpose operating system exclusively from free software. By using an open development process through public forums, the Red Hat engineering team hopes to provide an operating system more in line with the ideals of free software and more appealing to the open source community. Fedora Core is used as a proving ground for many new open source technologies that are in need of exposure to a wide audience.ÃƒâeurošÃ‚ Fedora Core 2 is also the first Linux distribution based on the 2.6 Linux kernel and already includes the next generation NFS protocol (NFSv4), GNOME 2.6 rc1 and KDE 3.2.1.
