RE: MS Anti Virus?

   From my perspective, a place that MS needs to also focus on is the
patch scanning technology.  SMS, WindowsUpdate, MBSA, all can give
different, confusing results even when scanning the same machine!
Please, give me a scanner that covers all of your internal products, and
gives reliable results.  Having one tool contradict another ends up
creating a mess, and it is frightening.  It's not fun to try and track
down a bunch of machines on a weekly basis to really find out whether
they are patched or not.

Does Microsoft read this list?

I will give Kudos to Microsoft for making an effort to IMPROVE themself
regarding security though.

All
of the worms that I think you are probably referring to all had
patches
well
in advance of the worm that impacted it, blaster, slammer, sasser,
etc.


Agreed.
I'm not saying that MS doesn't provide patches - they do.
I simply think that the amount of bugs in MS' OS' are to great.
If you install windows and attempt to either patch it or install
firewall
afterwards while on the live internet - Your chances of getting
infected
are quite high. The time it takes to install patches or a firewall may
in
some situations be longer then it would take for a user to get
infected.

I picture it a bit like a para trooper which has noo means of defense
until
he lands and can take cover.
Other OS' like FreeBSD take a different approach. All non vital
services
are
disabled until the user explicitly installs or enables them.

Microsofts products should provide the means to a secure patch before
risky
services like DCOM are enabled.
This should in fact be the case everytime a MS pc starts up.
Otherwise a pc which has been offline for a period may become infected
while
patching.

But ultimately MS have to catch more of their serious bugs before
releasing
their software. Consider how many resources that are spent on
patching.
Could they have been spent revising code in stead?
I wonder what the average load on the windows update server park is...


Home users never should have been impacted as they should be running
firewall software on the internet connections. The fact that they
don't
isn't MS's fault, however MS is stepping up with XP SP2 to help out.
On
top
of that they should be patching when necessary.

Corporate users shouldn't have been impacted either and were only
because
the IT department didn't keep the machines patched properly. Too
many
companies run on a deploy and forget strategy, this doesn't work for
any
OS
be it Windows, *nix, or ios. I am not saying keeping them patched is
an
easy
task, I managed 400 servers in a Fortune 5 company that were
distributed
around the world. None of them ran antivirus, none of them got
infected
by
either viruses nor worms, none of them allowed any but only a small
number
of people to have admin rights to do harm to them. When a patch came
out
that affected those servers, it was on the machines in a rather
quick
fashion, generally within 72 hours depending on testing times.


Thinking that there will never be code patches required isn't
realistic.
It
is humans writing the code and even the humans writing the other
Oses
make
mistakes and need to release patches. If the people who manage the
machines
don't take the time to apply the patches then the issue isn't an MS
issue,
it is an admin issue.

I know. I just wan't fewer. When you sell these amounts of
functionality
which is reused in multiple future software, then one should *REALLY*
test
it better, or lower the prices.



The *real* IT department could then link to the
executeable and place it on an intranet server
which would be secure.

This is an interesting idea but I can't see how one could do it in a
feasible manner in a large company that is receiving hundreds of
thousands
of emails from the outside a day. Also you would have to watch for
internal
emails and attachments as well because you could get an infected
machine
on
the inside. Now in large companies you are up to millions of emails.

My recommendation to the email manager at the time of the last major
outbreak where they started just stipping all ZIPs from emails was
that
they
strip ALL attachments that didn't have a specific internally defined
extension on them, that way they knew it was a purposeful thing that
that
attachment was there. The extension would be something specific to a
company
and people involved know that extension. Obviously this is just a
crutch
to
block the issue with well known executable file extensions.

The file associations are a tough thing to repeal since they are so
deeply
embedded in how things are done on Windows and people have gotten so
used to
them; it made life easier for a majority of the users and was a
great
idea
at the time. Now however, if you, for instance, removed the DOC
extension
from the file associations half the corporate Windows Admins out
there
would
be at a complete loss as to why Word wasn't working... Those bad
Windows
Admins are partially MS's fault, but mostly the fault of companies
who
look
for cheap admins versus good admins.

While I have no numbers to back this up, I do think that worms are
far
worse
when it comes to the extent of which viruses spread, and speed.
It is my belief that most worms are based upon MS exploits, rather
then
social engineering.

It is my belief that we will simply have to wait untill MS cleans up
their
act, which they should be doing, before the world becomes a better
place
to
live.

I realize that this doesn't clear situtations like the one above,
but in
general such situations can't really be solved unless all mails are
scanned
extensively, and / or the people are educate enough so that they
never
should run executeables recieved from mail (its actually quite
simple to
me). The *real* IT department could then link to the executeable and
place
it on an intranet server which would be secure.
