Make sure you secure it properly.
Do the following:
1. Install a firewall - apf with dshield and antidos is best
2. Disable telnet
3. Use only ssh2
4. Use on sftp (not ftp)
5. Disable direct root login
6. Use a separate IP and port for ssh
7. Install and run chkrootkit daily
8. Update and run the latest kernel and patches
Do the above and you should have a safe box.
