Mason, I do not think Marcus was beating up on you personally, and I don;t
think anyone else here would or has either. You have a tough world to
work from, that of a tech within an ISP. But the best that an ISP can do
is perhaps limited, and since the corp industry is still unable to beat
the problems that abound, and since gov sites both federal and state and
local are still up to their collective necks in internet-do-do, any
efforts from the ISP realms is welcomed though perhaps not to have too
drmatic of an effect. But, if each and every ISP forced into their
routers ingress as well as egress filtering, we;d have eleiminted a large
number of attack vectors and issues with the anonymity that many rely upon
for their nasty deeds.

As for the new value-adds of firewalls and spam filters offered by some
ISP's they aren;t going to sell well even now. Afterall, what are folks
seeking; a connection plain and simple and since education has not made
them really aware of the pitfalls they face, why are they going to pay
more for a service they don;t really seek let alone feel they need? There
is afterall more serious concerns for their wallets in gas prices
rising.... Now, if frewalls and spam filters were part of the base
offering, folks might or might not notice or be concerned and still
signon, though that's not a given either. Folks tends to in both the home
user realm as well as the corporate realm do these silly "full installs"
afterall, thinking if they do any less they are somhow limiting their
capabilities.

By the way, Marcus, love yer 10 list! spreading it all about the place
now. I had hesitated in replying to the user training side of the thread
as folks tend to view me as a pessimist, rather then a realist.

ingress and egress is the strong begining move to make. Marcus has many
tales to tell on how well that matter goes through the corp world, and has
I'm sure only related a few of those tales here...

Thanks,

Ron DuFresne

See the pessimist in my replies that it's cause more folks are
anticipating their wealth and fortune being tied to some gross error of an
employee of such and institution granting them full access to some
millions that appears to have laid dormant for a few years time. I'n
otherwords most folks have a bit of the take it and run ethics
builtin...it explains to my mind quite well why the 911 scams never seem
to be slowed in the slightest...

User education often runs counter to fighting human greed...

Of course, I have not fixed my speticles in about 10 years so the
prescription through which I view the world is likely warped...

Are my ideas ill-conceived? I shouldn't even call them mine, because
they are not unique to me - there are no unique ideas; just people that
get to claim discovery, because they were the first to publicly announce
an idea or act upon it. As to whether or not they will disintegrate, I
still don't know whether they will or not. I'm not going to know until
I try them or someone points out some specific areas in which they will
fail.

What specifically do you think is bullshit? Or is it just my approach
in general? The better I understand this problem the better off I'm
going to be.

I disagree. I don't think that N need be that large. Even now with the
huge mess we have, N is manageable if it is presented properly and
*people want to listen*. N can be reduced considerably if those
providing PCs, network access, etc can improve the security of their
offerings. This of course being a much longer term look at the problem.

Here are two ways of looking at N. The first one applies to the present
state of things, the second is longer term.

N in a positive reinforcement scenario (short term)
----------------------------------------------------
If as a group, we like to preach least privilege, why do we keep trying
to tell home users what they _shouldn't_ be doing? That sounds like
default allow. Why not tell them what they should be doing? It's going
to be a much shorter list.

N as seen from within a mature utility model (long term)
---------------------------------------------------------
Here's another way of looking at the long term size of N. In one of the
emails in this thread, someone mentioned that Internet access should be
like a utility. I'd like to take that analogy (because that's what it
is) and expand upon it.

Look at the electrical utilities (I'm going to assume North America).
Access to electricity is available to anyone that wants it - from large
massively energy intensive operations such as aluminium smelters right
down to your average home owner.

Electricity is provided to home users in a very well controlled fashion.
The utility puts out a very consistent 60Hz and the power is expected
to be within clearly defined limits of the amount of distortion, amount
of voltage fluctuation etc. The utility also provides automated systems
that are designed to protect their infrastructure as well as anyone
attached to it.

When the connection is made from the pole to the home, it must meet
strict electrical codes and certain parts of the installation (such as
your panel) must be done by an electrician. The only interface
presented to the home user that would allow them to actually touch what
they are paying for is a three prong outlet. Or if you are in the
bathroom, hopefully a GFI as well. (Well light sockets too, but I'm
trying to keep this simple.)

What do home users plug into these three prong outlets? The vast
majority of home users will plug in lamps, kitchen appliances, clocks,
computers, etc. *ALL* of which must be inspected and approved for
safety before being allowed to go to market. If a home user wants to
play and decides to stick a fork in an outlet, the rest of us are
protected by the fact that there is "egress" protection mandated at the
home - the breaker is going to blow. At this point, user education is
pretty simple:
Don't stick your finger in a light socket.
Don't let your kid stick a finger (or anything else) in an outlet (there
are even plastic outlet plugs for this purpose)
Don't blow-dry your hair in the bathtub.

These are not complicated rules. This is a very small value of N. The
reason that the rules are not complicated is due to the steps that
industry/government has taken to regulate the utility and to protect the
home user.

Getting back to computers and the Internet... If these sorts of controls
and industry maturity were in place, home users wouldn't be such a
problem. The big problem is that the Internet right now is very much
like the "Wild West" - it's young, immature, un-controlled and much
about how it should work is still unknown. It just needs to mature.

Uh oh. I didn't know I was coming across that way. I don't feel the
least bit like anyone has been beating on me. I'm enjoying the
opportunity to discuss my thoughts with such a group of informed people.
If someone does get genuinely upset with me, I'm quite willing to
hear what they have to say and see whether I think it's valid.

It's true that I'm not in complete agreement with all the replies I have
received (much but not all), but if I were, there would be no point to
all this... We'd just be a group of elitists all agreeing with each
other over how smart we are and how stupid everyone else is ;)

/me ducks

I honestly don't mean that :)

That's one of the things that I really want to see happen. I want to
see ISPs, right across the board, at least do some basics like
ingress/egress filtering for the really common ports and anti-spoofing.
I don't have any idea how many of the large ones do this, but I know
that a ton of the small ones don't.

It seems that there are two primary ways in which people change. Either
they make a conscious choice to change prior to a problem getting out of
hand (requires knowledge that there is an impending problem and
knowledge of how to avoid the problem) or they endure more and more pain
until they are forced to look at the problem and finally make a choice.

It seems to me that majority of home users fall into the second
category. So, education needs to target the few that are looking for
info, but don't know what to look for because there is too much out
there. The media is helping to freak people out, but it's not doing
much to offer solutions. In fact the media will eventually desensitize
people to the problems which will make the job of helping people
understand, even harder.

The other problem is that you can never expect or force a person to
change. So if your solution to a problem involves changing someone that
you have no control over, your solution is doomed to failure. The path
that is more likely to succeed involves moving forward with what you
have control over and those that are cooperating, all the while making
efforts to recruit more from the ranks of the uncooperative or ignorant,
but not requiring it.

Working from that philosophy; that means that the workable solutions
should be easier to spot. Here are a couple really basic examples:

What you have control over
-----------------------------
Governments put laws (sox is a good example) into place that force those
they have control over (businesses) to comply or face penalties.

Cooperation
-------------
Organizations and their members agree to address a problem as a group
and everyone voluntarily enacts what the group decided on. The
standards process is a decent example of this. I'd like to see one of
the large ISP associations hammer out some suggested best practises and
get their members on board.

I'd love to see that, but according to those with the business reins,
competition doesn't allow for that...

It really is hard to be an optimist sometimes... Thanks for your thoughts.

I completely agree.

In my previous email, I said that there are two ways in which a person
changes. In my opinion, the people to whom you refer are going to have
to endure a lot of pain before they decide to change. That's one of the
great things about pain - for those that want it, it's never in short
supply. Pain can be a great teacher.

I think you're wrong.

When you have irate customers on the phone saying that the fact their
computer is infected is your fault, or that they are getting all this
spam and we should be doing something about it, or that their connection
is horribly slow and we explain that it's because their computer is
filled to the gills with spyware and the customer has accidentally left
a p2p app running that allows un-restricted uploads, then I do think
that the ISP should be doing something about it. If enough customers
demand something of a business, it's generally within that business's
best interest to listen to their customers. If you happen to be in the
minority that doesn't want or need this sort of service, then perhaps
the ISP can find a way to give you access to your crap, but if it's
going to affect the other users that have expressed that they don't want
that crap, then you're probably going to find yourself hunting for
another ISP. I expect and hope that this is exactly what more and more
ISPs will begin to do, now that the problems are getting so bad.
