Subject: ISS Security Brief: "MS Blast" MSRPC DCOM Worm Propagation (fwd)

You're talking about the Internet Connection Firewall (ICF)? Firstly, if most
people even knew what a firewall was, then the impact of this worm might not
have been as severe. I'm sure you realize there are a lot of users out there
that bought XP for its "pretty" interface. Those people don't know a firewall
from a hole in the wall. If you tell them it can protect their precious computer
from evil script kiddies, then they might be more interested, but unless you put
that information right in their face, they're not going to bother.

As far as my friend is concerned, he wasn't using ICF, rather, he was using
Sygate. He knows what a firewall does, but he has no real experience that has
mandated he ever really configure/use a firewall. A firewall gives a user so
much power. To be able to block incoming and outgoing traffic is a pretty big
responsibility. Which ports should a user configure? How on Earth is an
inexperienced user to know? Unless you have experience configuring firewalls on
servers or managing a personal home network built for the security-conscious
people that go out and do lots of research, you will have no idea. Also, unless
a user with a firewall keeps up to date on advisories, that person will not be
very aware as to the urgency of filtering certain ports. Most people that run
windows and have heard about the "auto updating" service think that that service
is going to protect them from anything major, anyway. "It's an automatic
updating service. Microsoft isn't going to leave me hanging." Seriously, people
develop a false sense of security. You can give someone a firewall, but that
doesn't mean they'll know what to do with it.

I informed another friend of mine today that friend #1 [the one infected with
the worm] was infected with a particular worm based on a recently released
exploit. I told him he should secure his computer. His response was "But I have
an Anti-Virus program installed." More false sense of security. I cleared the
falsity of this claim up for him, of course, but he's more into computers than
your average user. He's a webdesigner.

My point is, there are people out there who need to be educated. I teach people
what I can to help them secure their systems on their own. I pull people out of
that false sense of security and that notion that if they modify any settings in
Windows that it will break. If they need to ask, I tell them I'm here for their
inquiries, and Google can take care of the rest.

Companies like Cox, on the other hand, go and filter port 135, and even outgoing
port 25! I had a long discussion with one of the techies that works at Cox in
regards to the port 25 filtering, because one day I could no longer connect to
my SMTP server outside Cox's walls. The tech said he didn't think it was the
greatest of ideas, but it was easier to just filter 25 than it was to set up
smtp-auth or pop-before-smtp. The same mindset was applied to port 135. I don't
particularly like the fact that those ports have been filtered. It seems very
restrictive, even though I can find other ways to get along without using those
ports in the manner in which they have been filtered. I don't even like hosting
services that install a spam-filtering agent by default. I want to receive the
mail and traffic that was intended for me. If I don't want it, I'll learn how to
filter it myself. Companies like Cox spend more money advertising than they do
educating people to make the Internet an overall more secure place for the
average user. Cox, instead, protects the ignorant people and keeps them
ignorant. I think Cox should have send snail-mail to each one of its users
describing its reason to blocking port 25 or even 135. That would have made one
HELL of a dent in the ignorance. Oh well, Corporate America.

People can learn! Teach them! Don't let them be ignorant. Ignorance is a MAJOR
security problem!

Of course we could just take the easy way out: How do you secure the Internet?
Kill all its users.
