The one time I had a Linux server cracked, it was through a bug in OpenSSH...
You should run unsecured and sensitive network services in a chroot jail, because if a hacker can break into a vulnerable service he could exploit your whole system. If a service is jailed, the intruder will be able to see only what you want him to see -- that is, nothing useful. Some of the most frequent targets of attack, which therefore should be jailed, are BIND, Apache, FTP, and SSH. SSHjail is a patch for the OpenSSH daemon. It modifies two OpenSSH files (session.c and version.h) and allows you to jail your SSH service without any need for SSH reconfiguration.
