SELinux. 1. Introduction Security-Enhanced Linux (SELinux) is a mandatory access control (MAC) security mechanism implemented in the kernel. SELinux was first introduced in CentOS 4 and significantly enhanced in later CentOS releases. A step-by-step guide to building a new SELinux policy module. Who’s afraid of SELinux?
Well, if you are, you shouldn’t be! Thanks to the introduction of new GUI tools, customizing your system’s protection by creating new policy modules is easier than ever. In this article, Dan Walsh gently walks you through the policy module creation process. Getting Started with SELinux - Overview. Following is a short discussion on why you should consider using SE Linux and how it fundamentally works.
Section 2.2 defines terms that will frequently be used in subsequent sections, so get familiar with them now. SE Linux offers greater security for your system. Users can be assigned predefined roles so that they can not access files or processes that they do not own. There is no "chmod 777" equivalent operation.
This differs from regular Unix permissions in that the user defined roles, or security contexts they are placed in, have limited access to files and other resources but in a far more controlled fashion. SELinux Tutorial. I have found very few resources for SELinux on the web, which I believe is a idea tool box for the security engineer or for that matter any average Linux user who plans to use programs of the web without examining them for hacks.
I have divided up this tutorial into 2 main sections, the first of which describes why SELinux is the coolest security tool ever followed by a detailed tutorial with a running example of getting up and running with it in no time. SELinux in a Nutshell The Big challenge is to find ways to have secure systems knowing that flawed application software will always exist. SELinux is an implementation of the reference monitor concept, where the operating system isolates passive resources into distinct objects such as files and active entities such as running programs into subjects. The reference monitor mechanism would then validate access between subjects and object by applying a security policy as embodied in a set of access control rules. Setting up SE Linux on FC6. How to Disable SELinux. You've setup a new system, or installed something new on your Linux system and its not working.
You get the feeling that SELinux is the cause of the problem. Configuration - RPM Fusion.
