Opps - so long since I bothered withthis stuff.
There do appear to be modules for mail scans and proxy scans (squid anyways)
to protect others on the network as you say below. But there are also parts
for file system scans. Overall it looks pretty good. Obviously you think
your linux boxes are too secure to bother with it. The writers of the
software do not appear to have the same faith.

AHhh. Here we go again blaming those who actually use the machines. We
have been through this before. Users will have the same technical skill no
matter whether their machine is a windows or linux one (unless linux comes
with a free mind programmer of course). Please do not compare users.
Compare machines AND take into consideration what they are for. Users are
necessary for the machine to be made and for sysadmins to keep their job.

Actually its a comment on your simple statistics and how valid they really

So, which OS would you like to be running."
Its an example of why your "statistics" is not valid.

Here we go blaming users. The computer, and hence th eoperating system, has
only one purpose - to serve the users. If you rate your system higher than
your users your are not a good sysadmin.

Yes but do people use the linux machines as much. Are they at each users
desktop? Do users get to configure them for their own needs? Or do you
have to call ISD and wait for 3 weeks after filling out four forms each time
you want to do something?
Don't forget your users are the most important thing on your network. Not
yuor linux/unix or windows machines.

What OS and what version are you using? Some are deliberately set as open
because that is what users want. However the file system and other versions
support the options.

And you expect them to be able to use linux? Is it the users you are

Actually I meant typing them into your web browser. Downloadable java
bytecode (applets) is just as dangerous on netscape as internet explorer.
Because IE is used more more code is written for it. Computer security is
not just about filesystem permissions. Its about protecting your users and
what belongs to them. [mmm..... about half the newsgoups have "security" in

Install means changing the system so the program will run. (Usually on boot
for malicous code). On linux config files have to me modified so things
will run on boot and the files have to be placed in the right spot.

You do this for windows OR linux if you have a rootkit installed. (Yep -
watch out for your NT rootkits)

Thanks for the explanation.
My tripwire logs change each time the machine does anything (like system
updates etc). Unless you know every file in every package on yuor system
(as most of your users would not) you don't know what is happening. This
may be OK for someone who's only life is a computer but hardly a thing to do
for a busy person who has real work to do or is a casual home user with a
family to run.
BTW there are tripwire like programs available for windows as well. Most
home users find them difficult to understand as they would if they had a
unix box in front of them.
> > a large number of start points for malicous code
> What does this mean?!?!?
Just what is says. There is a large number of script places where some
malicous person can start a process and you would never know were it
BTW: My original point is that windows machines may appear to be more
susceptable to attack because of how they are used - not the OS itself.
This includes the type of users (as in not so technically skilled - have a
real life - people) and the number of users of that type. Much of your
argument has appeared to agree with this but used derogatory statements
about those users instead of making a considered view on whether the OS
[either linux or windows] can compensate for their behavour.
One thing that RedHat has done to assist home users over the past few years
is have the firewall setup during install (unfortunately it still used
ipchains on the version I have) and have services not normally used on the
desktop switched off. These are quite basic albiet important changes to
earlier versions if you want linux to break into the desktop market.
