Wrong.

Why are you running utilities from a company you don't trust? In fact,
with your obvious hostility towards MS, why are you running windows in
the first place?

Any program you didn't code yourself is going to do a lot of things
without asking you for permission.

Legitimate programs for obvious reasons don't need to be controlled.

Furthermore, an outbound control measure is not going to indicate in
any way if what it's doing is good or bad. You just have a
preconceived opinion about it being bad (which just proves that you
are running software you don't trust).

or they just know their own OS well enough to realize that host-based
outbound control as a security measure against malware is a lost
battle.

In some areas it is.

Do you realize the number of kernel hooks necessary to accomplish such
a task? And still it isn't even close to being reliable.

You probably also never considered the increase in attack vectors
introduced by PFW's.

If you know how to internally stop the Sysinternal Help utilities from
calling home please post your findings here. I would also like to hear
your advice and solutions as to port monitoring and outbound traffic
in general on Windows operating systems. Should users follow your
advice and ignore all outbound traffic? Should outbound traffic be
allowed to outside networks or should it be limited to the local network?

It's not the app itself "phoning home". Clearing the
CodeBaseSearchPath key in the registry (Internet Settings) probably
does the job. But maybe it's not such a good idea after all.

Anyway, if you had taken the time to packet sniff the "phoning home"
instead of letting your PFW drive you paranoid, you would probably
have realized that it's no big deal and that this big scary MS thingy
isn't really spying on you.

App's like CurrPorts and WireShark come to mind.

>Should users follow your advice and ignore all outbound traffic?

Users should think twice before installing all kinds of stuff. And
they should not let PFW's drive them paranoid. Problem is, neither the
PFW nor the user understands what's happening. I've seen users freak
out about app's "phoning home" to IP address 127.0.0.1

>Should outbound traffic be allowed to outside networks or should it be
>limited to the local network?

That's for the person in charge of the local network to decide.
However, there won't be much inter netting without allowing outbound
traffic.

Yes it is. If you use the help utility it calls an Akamai server. I
know why it's doing it and I am not saying that it is necessarily good
or bad. The example was used to demonstrate that there *are* things
making outbound connections without users being aware. If the
applications that we think of as "tame" are doing it you can be sure
that other not so tame applications may also be doing it.

Once again, I know what it is doing and I am not saying that anyone is
spying, that is not the point. The point is that Microsoft and many
others are consistently saying that monitoring outbound connection is a
useless firewall feature for *any* reason. I disagree with that. All
good firewalls have outbound connection monitoring available, the
Microsoft XP firewall doesn't. When users made mention of this, or if
they asked why it wasn't available, the response from Microsoft and its
fans was to embark on a campaign of discrediting all firewalls that do
outbound monitoring and to claim the feature as absolutely useless.
When that tactic failed they then decided that anyone who even suggests
that the firewall should do outbound monitoring should be immediately
clobbered, it may keep some people quiet but it won't keep me quiet.
Microsoft customers spoke and asked a valid question. Instead of
Microsoft saying something as simple as: "We have received requests for
this feature and are investigating the possibility of including it in a
future update", they decided that it was best to kill the messengers
and to proclaim their firewall as superior to all others.

Brilliant. Give that to novice users. Instead of having the firewall
do what firewalls usually do have the users dig about and find utilities
on their own to do the job! And for your information you don't have to
go out of the Microsoft stable to find port monitoring tools.

More BS. There are all kinds of computer users and computer users do
all kinds of things. Good firewalls know what is going on and most
seasoned users know what the loopback address is. The simple fact that
the extra ability to detect outbound connections can be a useful
firewall feature is something that guys like you are insisting on
denying. You are on a campaign to discredit this as a useful feature,
but you offer no simple, easy way or alternative for users to even have
basic outbound connection monitoring.

No there won't be. But that doesn't mean that everything installed on a
computer should be calling out and it doesn't mean that firewalls that
help identifying those "call home" utilities are bad, useless firewalls!
If that is the case then why would Microsoft include such a useless
feature in its newest flagship operating system? And then insist that
it is useless for XP users?

No. It's windows. And I provided you with a way to stop it.

So, why is it doing it?

Hmm. If you don't consider it bad, what's the whole fuss?

Of course. The net is a resource like anything else. Soon you will see
app's taking advantage of online services just like if they were a
part of the app itself.

That wasn't my impression.

Then what was your point of going "are you aware that sysinternals
utilities phone home"?

That's actually not what they are saying. Do some more research.

*sigh*

More *sigh*

BS argument. A novice user with no basic networking knowledge isn't
able to properly configure any packet filter whatsoever.

>Instead of having the firewall do what firewalls usually do

What exactly do *real* firewalls usually do? They definitely *don't*
run on an insecure platform together with all kinds of other stuff
under the control of a clueless user with unrestricted rights!!

Calling PFW's firewalls in the first place is an insult to real
firewalls. They are host based packet filters.

>have the users dig about and find utilities
>on their own to do the job!

One can't "get the job done" until one understands it. That's why
novice users should stick to the windows firewall. It's on by default,
it works, and it requires no further action - which is about the
maximum you can expect from a novice user.

I know that perfectly well. I just mentioned some of my favorites.

Now, THAT is BS, right there. These firewalls have, for obvious
reasons, NO idea what's going on, which is why they have to ask the
user.

>and most seasoned users know what the loopback address is.

But novice users don't. The fact that PFW's even provide pop-up
messages about the loopback interface shows the developers lack of
competence.

Wrong. You simply fail to get the big picture.

If so, you and your PFW followers are on a campaign of making clueless
users believe in hype and astrology-like pseudo security.

Depends. If it provides a false sense of security, it's very bad. If
it's misconfigured by clueless users, it's very bad. If it interferes
with what the user is trying to achieve, and the user doesn't
understand why, it's very bad. Since it mostly doesn't mean more to
users than that they will temporarily switch it off if something
doesn't work, it's very bad. If it adds further vulnerabilities to a
system, it's very very bad.

> If that is the case then why would Microsoft include such a useless
>feature in its newest flagship operating system?

They have already explained why. You need to catch up.

>And then insist that it is useless for XP users?

Could it be that Vista provides a slightly better foundation for doing
so?
