Won't help. What's the first thing people do after re-installing
the operating system (still have all the original CDs and keys and
product activation codes and and and)? Connect to the Internet to
download the patches. Time to download patches 60+ minutes.
Time to infection 5 minutes.
Its possible its a problem on dialup, but in our ISP office I setup new
win2000 servers and first thing I do is download all the patches. I've yet
to see the server get infected in the 20-30 minutes it takes to finish it
(Note: I also disable IIS just in case until everything is patched..).
Similarly when settting up computers for several of my relatives (all
have dsl) I've yet to see any infection before all updates are installed.
Additional to that many users have dsl router or similar device and many
such beasts will provide NATed ip block and act like a firewall not
allowing outside servers to actually connect to your home computer.
On this point it would be really interested to see what percentage of
users actually have these routers and if decreasing speed of infections by
new virus (is there real numbers to show it decreased?) have anything to
do with this rather then people being more carefull and using antivirus.
Another option if you're really afraid of infection is to setup proxy that
only allows access to microsoft ip block that contains windows update servers
And of course, there is an even BETTER OPTION then all the above -
STOP USING WINDOWS and switch to Linux or Free(Mac)BSD !
Patches are Microsoft's
intellectual property and can not be distributed by anyone without
I don't think this is quite true. Microsoft makes available all patches as
indidual .exe files. There are quite many of these updates and its really
a pain to actually get all of them and install updates manually. But I've
never seen written anywhere that I can not download these .exe files and
distribute it inside your company or to your friends as needed to fix the
problems these patches are designed for.
The problem with Bots is they aren't always active. That makes them
difficult to find until they do something.
As opposed to what, viruses?
Not at all! Many viruses have period wjhen they are active and afterwards
they go into "sleep" mode and will not active until some other date!
Additionally bot that does not immediatly become active is good thing
because of you do weekly or monthly audits (any many do it like that) you
may well find it this way and deal with it at your own time, rather then
all over a sudden being awaken 3am and having to clean up infected system.
