Nope, in the true def, NAT is a possible feature found in firewall
products, but NAT is not a firewall product. NAT does not have to block
inbound, does not really check for anything, just blocks unrequested
inbound.

so nav and quickbooks are suddenly free? and install themselves, of course?

so you mean you expert mother-in-law is canny enough to get oem, but she

i have the following questions:

1. how much is a trip to bestbuy that gets you all the software that you
need?
2. why are we no longer discussing the ease of installation, but rather
construct more and more fairy tales to justify the use of proprietary
software?

what do mean "only"? are you saying that you consider a 50% savings
insignificant? i mean, even *if* your "calculations" represented reality.

so now it is definitely about lock-in in the form of some menu structure,
and no longer ease of installation, right?

or rather, what this is really about is struggling to find justifications
for using proprietary software instead of perfectly fine, free,
spyware-free, no-home-dialing open source alternatives---which, i think
everybody here understands that, is not an easy job, considering that you
effectively have to convince people that it's a good idea to part with a
thick wad of cash for essentially no good reason whatsoever.

oh well.

But your mail client does make requests. It asks your mail server if it
has any new mail for you. And then that (possibly infected) mail slips
through your NAT like magic. Or am I wrong?

maybe on windows they do, since they need to in order to install anything.
on many linux machines, the root account is not even shown in the graphical
login menu, so you would explicitly have to su in order to cause trouble.
most users will simply use the root password when they start some
configuration/installation program that requires it. while remaining logged
on as themselves, of course...

Because they believe in security through obscurity?

I never disputed that. What I dispute is your claim Unix architexture is
better than Windows. My discussion was on the basis of security architecture.

The NT kernel [including the W2K and W3K] has security designed into the kernel.
Among the concepts are:

The idea of security parameters and user account settings that allow a much finer
granularity than admin/non-admin [or rott/non-root]

A file system design that also allows greater flexibility in designing discretionary
access control

Everything I have seen about the NT code base shows that security was part of the
architecture and *potentially* allows a secure implementation to be developed.

I do not see any indications that the design included mandatory access controls and
I am pretty sure no attmept was made to close covert channels.

I have no idea what you meant here. The Unix kernel does not include any security
built into it. Security in Unix is an add-on [a well done add on that does provide
good implementation but it is still an add-on]. The unix user accounts still do not
have the concept of differential authorization [you can grant higher priv's to
individual accounts without giving them root].

: If you mean 'rings' in memory protection, the idea goes back to Multics

Do I do not. I wrote what I meant. Unix inherited the basics of memory management
from Multics but did not have the hardware structure to implement the Multics
model.

: completely ignored it. 80386 had even better memory management features.

But this still is not the same has having security designed into the hardware and
using that to assist in your system design


From my standpoint, Unix [and Linux] as well as Windows are not as well developed
and implemented in the terms of security as the systems I worked on. All three
have deficiences in their design and implementation that make them not as secure.

It is highly unlikely that either of these system will achieve anything higher
than C2. The Unisys 2200 [C series] actually got a B2 rating and the M series
was designed to potentially acquire a B3 rating.

I also want to remind people that I have made no claim that Windows NT and above *as
delivered* is more secure than Unix or most Linux distros *as delivered* today. This
is not the case. Hoewever, as has been stated by others, one can harden a Windows machine
so that it can function with certain things open to the net. I would be more prone
to use Unix in this case.

I'm not missing the correlation. I'm questioning it. You haven't
controlled for all the variables here. That's my point. All patches
are not equal.

that must be it. i am convinced. i'll take 500 bucks out of the bank, drop
them at bestbuy, and get some xp/nav/ms office for my home machine. right
now.

That's funny, because Bill Gates *does* consider the browser to be part of
the OS. He even cited that in court during the anti-trust mess over IE as
being the reason IE could not be removed from Windows.

Seeing as how we all know that statement to be completely false, that
makes one think...Can I trust the products from a company that would
knowingly give false information under oath?

Which part(s) of the actual installation represents it?
Specifically: the Windoze GUI is integrated (whatever that means, if it
means anything at all). Is that "integration" referring to "being part
of the kernel"?

OK.

I'm really curious about a couple of things. NT had drivers in protected
mode. Since the great unification (and one can't have that without kids
being able to play games, can one? ;-)) those drivers are out in the
wild. Any faulty driver (intentionally malicious or not) is a potential
liability.
1. Since M$ honchos are trying to convince us that every new flavour of
Windoze is more secure/stable then the previous one, how does that
"compute"? Specifically: was that protection a part of the kernel or
not?
2. Why would anyone invest anything into (making of) a kernel with such
security potential if one then makes a complete mess out of the
surrounding system?

Can we agree on patches marked "security related" on the RH errata list
is a security related patch, and as such would be reasonably equal to
security related patch issued from Microsoft? If so, then that doesn't
change the number of patches I counted. I bet if do a google search,
you'll find my original from 2 years back with the actual numbers in
it...

I wonder if you are sober. That link points to a long list of
instructions on how to modify Local Security Poliy, the Registry and
other sensitive part of Windows. Doing that sort of thing would be
suicide for the average PC user.
