Want to know how to make Linux really secure? Security Enhanced Linux (SE Linux), a system of security policies developed by the NSA, let you secure Linux at every level from the kernel up. Find out how EnGarde Secure Linux and others build and maintain a truly secure server environment.

Hi, and welcome to the third in a series of articles on Security
Enhanced Linux. My first
SELinux article detailed the background of SELinux, while my second
article in the series discussed how SELinux makes access decisions.
This week, I'll talk about how an SELinux system differs from a
standard Linux system in terms of administration. Most of what you
already know about Linux system administration will still apply to an
SELinux system, but there are some additions and changes that are
critical to understand when using SELinux.

Hi, and welcome to my second of a series of articles on Security Enhanced Linux. My previous article detailed the background of SELinux and explained what makes SELinux such a revolutionary advance in systems security. This week, we'll be discussing how SELinux security contexts work and how policy decisions are made by SELinux.

Security Enhanced Linux, or SELinux, is an exciting security project
that is reaching maturity and poised to revolutionize the way Linux
security administration is performed. Originally developed by the
National Security Agency and released as an open source project, but now breaking into the mainstream in Red Hat, Fedora, Gentoo, and the new release of EnGarde Secure Linux 3.0, it incorporates Mandatory Access Control into a base Linux system. This is a revolutionary advance, but is also very different from the standard Linux security model. This week in Hacks From Pax, I'll provide a basic introduction to the philosophy behind SELinux, and explain how it can add a powerful layer of security to your Linux system.

Linux Labs International, Inc. ( LLII ), the world leader in Linux-based clustered supercomputer engineering, announced today a key milestone for security in supercomputing technology. With today's release of Nimbus 4.0, its out-of-the-box Linux cluster distribution, the leading Single System Image cluster architecture ( bproc ) is now seamlessly integrated with SELinux, the Security Enhanced Linux platform ( SELinux ).

"The National Security Agency built a version of Linux with more security tools that its technologists believe could help make the country's computing infrastructure less vulnerable. They've won over the Linux developer community with the changes. But success depends on its adoption by U.S. companies and government agencies, something that remains very much in doubt. (ed: not to mention adoption by Joe User, who is depending on his vendor to make this thing workable) |

SElinux is an impressively designed but notoriously hard-to-configure set of kernel hooks that enforce Orange Book-style security on Linux. Full support for SELinux takes effort, but when I first heard about Fedora's new targeted policies for SELinux, I was willing to tell the Red Hat folks "thanks, but no thanks." A conversation with their Dan Walsh changed my mind. |

One of the much-talked-about features in Fedora Core 3 (FC3) is Security-Enhanced Linux, which some people believe will make Linux a truly military-grade secure operating system. But SELinux is available to secure many other distributions as well.

If a must-have, must-know innovation exists for Linux's future viability, you might place all bets on Security Enhanced Linux. Vastly misunderstood and underrated, SELinux provides a marketing differentiator that could carry Linux deep into infrastructures that so far have shown lukewarm acceptance of the open-source operating system. SELinux transforms standard Linux from a cost-effective and secure operating system into a behemoth.

SELinux enforces mandatory access control policies, which limit user and application privileges to the minimum required to do the job. In contrast, most operating systems have DAC (discretionary access control) schemes in which a process has access to everything available to the user who launched it. . . . |

Operating system security is (or at least should be) of critical importance to us all. However, the varying levels of security required differ for each systems administrator. . . . |
