University Of Chicago Warns PC Users, Limits File Sharing
University Of Chicago Warns PC Users, Limits File Sharing
by , 8:00 AM EDT, September 14th, 2004
Talk to most IT folks and they will tell you that managing a network full of Windows boxes is no picnic. With new viruses and worms appearing regularly, and the associated patches and updates to combat them following close behind, the only thing Windows administrators are sure of is that they'll always have something to do.
The insecurity of Windows has become legendary; more schools are putting offerings from Apple in bookstore this year, and students are snapping them up, partially to combat the pain associated with maintaining a Windows PC in a campus environment. Just how much of a problem Windows users on campus face came glaringly to light for new and returning students at the University of Chicago this year, when they were greeted by a note titled "Policy on Windows Networking in the dorms" from the school's Networking Services & Information Technologies department. The letter starts off by describing the enormity of the problem facing students and the IT department:
As you may be aware, computers running Microsoft Windows are being broken into at a higher rate with each passing year. This is very much the case on corporate networks, but it can be an even larger problem for university networks, which tend to be more open to attack. The University of Chicago's network is no exception. At Chicago, over 3,200 computers running some version of Microsoft Windows were broken into last year, and we estimate that the 2004-2005 school year will be even worse. Last year the most frequently compromised computers belonged to students in the University's housing system, even though the computers in the housing system are a minority of the Microsoft Windows computers on the University's network.
Networking Services & Information Technologies (NSIT) has done several things to try to mitigate the damage caused by worms and viruses that target Microsoft Windows, including blocking some traffic at the edge of the campus network. Unfortunately, in a network as large and as open as the University's, this does little good. Once a single computer infected with a worm is brought inside the University's network, the worm will run unchecked within the campus network. One compromised computer will turn into hundreds within a few hours.
The note then goes on to offer some solutions for Windows using students, part of which is to provide firewall software and requiring its use on all PCs. Further, the letter states:
Starting with the 2004-2005 school year, for both your protection and that of the rest of the campus network, we no longer permit computers running remotely accessible Windows Networking services to use the networks in the housing system.1 Since the University has made this software available at no cost to all students, a firewall which blocks Windows Networking traffic will now be required on all hosts in the housing system This applies to computers running all versions of Microsoft Windows, and some systems running Mac OS X (those explicitly configured to share files with Windows computers).
You can read the full letter to the students at the University of Chicago's Web site.
What the IT guys at the U of C are effectively telling students is that there will be no file sharing in the dorms, which effectively isolates each student's computer, thus slowing the spread of any digital contagion. (The U of C is blocking ports 135, 137, 139, and 445, which are used by Windows to allow file sharing and other network tasks.)
Apparently, students will still have access to other ports that allow Internet access, which could allow web-based file access. Also, Mac users can still share files between each other since AppleShare uses other ports, and lets you make secure connections through SSH (Secure Shell) ports.
Special thanks to Dan, a student at the University of Chicago, for alerting us to this story.
The Mac Observer Spin:
The moral of this story, of course, is that students who have not made their choice in computing platform may want to seriously consider owning a Mac; it could make your college life a lot simpler.Observer Comments
Well, duh! Owning a Mac in ANY capacity makes life a little easier. Here at the U of Az, owning a Mac is very much encouraged, and most of the administration owns Macs and the UA runs on mostly Macs and Mac servers. On the UA ResComp (Residence Computing) website it has a five page dissertation on WinDell security, and the very last line is simply "There is no security threat what so ever to Apple computers at this time". ![]()

We use laptops here at Winona State, and the Mac share has doubled in the last 2 years, from about 5% to 10%. That may also have to do with the fact that the pc provider changed from IBM to Gateway, but given the number of iPods I see on campus, I think Apple is gaining momentum with the key 18-24 demographic.

The best part is that students using the Mac in college are going to have a hard time "switching" to PCs in the home when they graduate and are going to spread the word at work when their company's IT is hit with major problems. Very good for Apple in the long run.
By the way, the Cram & Jam would also have been a factor in choosing Mac notebooks - $200 off an iPod is pretty good motivation!
Mr. Jackson doesn't like Macs...

Daring Fireball said it best:
QuoteWindows apologists have long argued that the only reason the Mac has been so strikingly free of security exploits is that it has such a smaller market share than Windows. This argument ignores numerous facts, such as that the Mac’s share of viruses is effectively zero; no matter how you peg the Mac’s overall market share, its share of viruses/worms/Trojans is significantly disproportionate.....The reason this argument is so popular with Windows apologists is that it’s a convenient bit of rhetoric....You can’t get past this argument, because it can’t be disproven without the Mac OS actually attaining a Windows-like market share....Given that the Mac is never going to attain a monopoly share of the operating systems market — that merely expanding its share to, say, 10 percent would be universally hailed as an almost-too-good-to-be-true success — isn’t it thus only logical to conclude that the Mac is forever “doomed†to be significantly more secure than Windows?...
Well said Mr. Fireball, well said...
I was going to quote Daring Fireball as well, good work there AFCdtLoeb! What I can't understand is why its so hard for Win apologists to admit that OS X is infinately more secure than Windows. All they usually do is throw the low market share arguement into the mix then run away. As Mr. Gruber stated before the number of trojans and viruses for OS X is effectively ZERO no matter how you look at it, there's no getting around it.

OK. I know I might start an attack here BUT, this does need to be said.
OS X may not have as many weaknesses as Windows. However, that doesn't mean it will always be "strong" or "impenetrable" as some like to describe it. We must remember that although it's based on (runs on top of ) Unix, OS X in and of itself is NOT pure unix. Therefore, due to Apple wanting to continue its reputation of 'ease of use' and 'application interactivity' (iLife) there will be, more than likely, times when there is a found hole that can disrupt our happy lives.
Everything that is connected is not only hackable, but breakable. Some things may be harder than others, but as long as you even for a minute, get online to check email, there is a part of your life that has just become less safe.
So. In naivete, don't ignore virus checking software for Macs. Don't ignore firewall software for Macs. On top of not only just protecting yourself, you also can become a 'stopgap' for the crap that can, and *does*, get passed along by Mac users to Window users. In the very least we can slow the vicious cycle down.
And didn't someone say one time, 'pride cometh before a fall?'
Historically it can be seen that as soon as one becomes complacent in covering your ass, your ass gets busted.
All the above is just a friendly reminder that we do still need to stay on top of our game to continue to be successful in our digital lives.

What I meant wasn't that Apple has ever claimed that, but that over-eager users have batted such phrases around when describing security on OS X.
I mean, seriously, you want protected data? Then don't connect to the net.
Obviously, this hinders a lot of things, including some business' mere existence. But the point is that, no matter how good the security, the hardware, the whatever.... everything is breakable.
Yeah, Apple has never said that, it's the masses that like to boast, and some, in their boasting, forget to just be protective of their stuff. That's all....
Tue Sep 14, 2004 4:05 pm Subject: Haha! iLemmings believe everything they read!
You really beliebe that Apple is more secure than Windows?? That's because your srupid and dumb! You iLemmings will believe anythng that you read and I'm really smart and know a lot about alot of really interesting computter stuff.
Ha ha iLemmings!! I got you there!!! iLosers!!
See, I'm right, and have always been. Check the facts:

How the tables have turned. Not so long ago use of Macs were discouraged in most places.
