[SATLUG] Questions about home server security

Personally my home server runs: Samba, Apache, SSH, and CUPS, but only
Apache and SSH are open to the internet.

SSH: I run SSH on a non-standard port with complex passwords, root cannot
log in via SSH, and I use
and does not "call home").

Apache: I obfuscate server info from the HTTP header, obfuscate 404 error
server info, CGI execution if off, server side "includes" are off, and I do
not allow directory browsing. I am playing with the idea on installing
Nginx on my Raspberry Pie and setting up a reverse proxy for my Apache
server. Any thoughts on hardening Apache or on using Nginx would be
much appreciated.

Router: Runs DD-WRT with heavy logging and I have many types of requests

Additionally, head here <http://www.grc.com/intro.htm> and verify what
ports are open.
