Some attacks can be prevented with SELinux and ssh although it is just recently gaining confinement. If someone out there wanted to experiment with using SELinux to further confine ssh, it might be an interesting experiment, (any university student looking for a project?) SSH currently has privledge separation which we could take further advantage of with SELinux and the setcon call, but no one as done this yet. SELinux will prevent things like buffer overflows in ssh via the execmem/execmod/execstack/execheap prevention. It also stops attacks like grabbing the /etc/shadow file without a password. > > I'm new full time linux user, having temped with one or two distros in > the past, and I have to say that my experience of selinux has been > frustrating.
