SE Linux is a high security Linux system implementing Mandatory Access Control (MAC) among other things. It was originally created by the United States Government's National Security Agency. The official NSA SE Linux webpage can be found here.

SE Linux is being included in RedHat?'s distribution of Linux as of Fedora Core 2. The Fedora Core 2 SE Linux FAQ is here.

Notes from my debian installation. New fedora notes should be coming soon.

To add a new user:

suseradd

and make sure they are in /etc/security/default_context /etc/security/selinux/policy/users

tessier_: The default policy should work for a play machine as long as you make sure that you remove the root line in the user's file.

se_apt-get se_dpkg-reconfigure se_dpkg se_dselect

sadminpasswd to change a users passwd

spasswd to change roots passwd

tessier__: Use the type ROLE_home_ssh_t for the ~/.ssh directory and all files under it.
