Recommended minimum security for making a PC accessible over the Internet...?

["fondlezz" <amkilgore@xxxxxxxxxxxx>]

Hi all,

Following on from Dean's unpleasant ordeal, I was wondering just how
much security is needed/recommended for the standard home user who
makes a PC accessible over the internet.

I, as I imagine quite a few others do, have a "server" at home
which
I can connect to for various things (FTP, HomeVision, Slimp3 etc.).
At present, I have no added security other than what is provided by
my router and the applications themselves.

The only precaution I do take is that I only open ports as and when I
need them - i.e. the only port left permanately open is the remote
management port of the router which lets me open/close the other
ports as required.

Should I be doing more...? (I know that's a "yes" already ;o))
What do you guys recommend...?

Thanks,
Andy.

P.S. Dean, I hope you get it all sorted... :o)
