Hi Eugene,
Following up my own posting to this list and subsequent comments, I've assembled a web page with short security guide. Please have a look and send me comments/additions/corrections:
Nice gesture! Perhaps the following would be nice/appreciated by others: 4. Perhaps a link to some ssh client software would help people: http://directory.google.com/Top/Computers/Security/Products_and_Tools/Cryptography/SSH/Clients/6. Perhaps a link to some Win32 Freeware scp client (besides putty): http://winscp.vse.cz/eng/
8. Let's install logcheck (http://www.psionic.com/abacus/logcheck) and run it through cron.
10.A Get a decent portscanner, use it and don't forget to configure portsentry to disregard your own IP.
Buhbye... Nico
