Subject: [OT] security issues

For Donald and some others:

I know everyone isn't made of infinite money, but generally I don't prefer to
run a firewall on the machine I'm using (doubly so if that
box is a Windoze - read: security hole - machine). Even Linux boxes
tend to have so much ubiquity that there are quite a few common hacks
and not everyone knows enough to lock-down the box. And it only takes
one hole.

So I was going to suggest people that can afford to think about it at
least look into some of these separate dedicated firewall/hub
combinations. Many either are a well locked down linux distro or use a
proprietary OS so common attacks don't work against them. And they're usually
not so hard to configure (if any configuration is required).

If you want to run web servers, etc, I'd really advise not doing it on your
main home machine (IIS that goes times ten for). Get an old
486 or P-II or something and serve from it. And learn about locking
down your web server or ask your nearest neighbourhood geek.

Alternatively, think about a removable HDD to store your personal data... then
the worst that gets trashed is your applications which you can reinstall.

And (as Donald points out) make sure your drive imaging or backup software is
up to date and you have frequent backups.

Setting up your PC in such a way as to leave it exposed to the net leaves the
script kiddies and the real crackers plenty of time to take a shot at it. And
most of the kiddies will trash your machine just because they can. There are
not many 'white hat' crackers out there willing to help you by identifying
problems on your machine and NOT doing anything bad.

Here's a list of some of the greatest danger areas, ways to identify them,
ways to fix them, thanks to the FBI and SANS:

The net is an ugly place. Don't surf unprotected!;)

Also look into getting an elderly 486 and someone like me to lock it down for
you. It's usually cheaper than the proprietary thing, and if
(make that _when_ there is a problem discovered you can bet it'll be
fixed a whole lot faster...
