on the issue of IP related network security?  yeah, I would say MacOS is 
more secure.  Here's why....
In a firewall environment, what would you say is common sense as far as 
rules go....."deny all, allow what you need".
Most flavors of unix come outta the box with everything enabled (same for 
NT), we all know that, I think.  With the MacOS, if you want to activate 
a IP related Network service, you have to install it and tell it to run.  
It doesn't come outta the box enabled....which fits ...dare I say 
..."accidently" into the same thought of proper network security.  No, 
noone designed this into the role of the MacOS for security needs, that 
much is obvious.  But that's how it works.  And for people ranging from 
Graphic shops to people like NASA, it works great, cause that's one less 
sysadmin (*owch*...that's my job) they have to hire to install, configure 
and maintain a Unix/NT box.  Thus...there's the reasons for going with a 
MacBased server in some shops.

Again....why buy an OS with all these fancy logins, daemons, & services, 
when all you want to do is offer some doc's up on the web, securely?
With NT, you'd just end up trashing most of them in the recycle bin.

Yeah, but with the MacOS, I still can leave things like filesharing, and 
other networking services ON and not worry about security.  Heck, I could 
leave the Guest login with write permissions enabled on the Mac, and 
still run a secure server on the Net.  (AppleTalk doesn't route over the 
net, without some very special plugins, which don't come standard.)

With a NT/Unix box, if I shutdown everything, ....except HTTP or 
FTP...it's now a dedicated machine....and I can't even use it as a print 
server or a file server.

Yes, but with the Mac, things get very complex, because typically, you 
pass commands to a "command line interface" via the httpd.....where's the 
command line interface?

If you know how to break that kinda security, I would suggest that you 
take a look at the contest going on right now....at hacke.infinit.se (I 
think is the addy), cause you can win a lotta money if you hack thier 
Mac. :)

Okay...in consideration to everyone else on this list who could give a 
damn...any further posts on this subject I would ask that we take it off 
this list, as this has gotten WAY off subject, and I never meant for us 
to get there....feel free to reply to me personally if you wish to 
continue this discussion please.  I'm sure at least half the people on 
here could care less about further OS battles.  I won't respond to 
anything that is either TO: or CC:'d to this list, as long as it's this 
subject.  :)
