Welcome GUILinux members and all Free Software users!
After discussing ways in which the two sites could cooperate for the mutual benefit we have decided to join GUILinux.com and Nuxified.org communities to create a bigger and better Free Software support community at Nuxified.org.
Instead of maintaining two separate websites with the same direction, which seemed unproductive and felt like more of a competition than a great Free Software and GNU/Linux family, we think that together we can do more. We hope that all GUILinux.com members and contributors feel welcome in their new home. And we hope that anyone that has questions about GNU/Linux (and even other Free Operating Systems), no matter how great or small, will still look to us for answers. By teaming up, we should be able to succeed in providing better and innovative support, better discussions, and a better community as a whole.
Security-enhanced Linux (SELinux) is an implementation of a mandatory access control (MAC) mechanism. This mechanism is in the Linux kernel, checking for allowed operations after standard Linux discretionary access controls are checked. Standard Linux security is a discretionary access control model (DAC).
Discretionary access control (DAC)
DAC is standard Linux security, and it provides no protection from broken software or malware running as a normal user or root.
