I’m really happy to announce that SELinux is now available in Ubuntu 8.04 “Hardy Heron”. This is the result of the amazing work of the ubuntu-security and ubuntu-hardened teams, as well as the huge contributions from the folks at Tresys. (note: SELinux will not be the default, but is available as a security option.)
If you would prefer to use SELinux over AppArmour, or if you’re just a good soul that would like to help test Ubuntu’s SELinux implementation, please read on.
Install SELinux in Ubuntu 8.04
All that is needed is to install the SELinux package, which will remove AppArmour and apply the SELinux policy.
sudo apt-get install selinux
If you run across any issues or bugs please report them against SELinux on launchpad. Welcome to a more secure Ubuntu!
