University Professor Chastised For Using Tor

Irongeek_ADC writes with a first-person account from the The Chronicle of Higher Education by a university professor who was asked to stop using Tor. University IT and campus security staffers came knocking on Paul Cesarini's door asking why he was using the anonymizing network. They requested that he stop and also that he not teach his students about it. The visitors said it was likely against university policy (a policy they probably were not aware that Cesarini had helped to draft). The professor seems genuinely to appreciate the problems that a campus IT department faces; but in the end he took a stand for academic freedom.

    Widespread use of Tor could be a huge headache for network-security administrators, particularly in higher education. My university alone has more than 21,000 students. Imagine what would happen if even a tenth of them and a similar percentage of faculty and staff members started using Tor regularly. With all the spam scams, phishing scams, identity theft, and related criminal enterprises going on around the world many of which involve remotely hijacking university-owned computers we could approach technological anarchy on the campus.

    How does Tor enable those things, and how would more people using Tor make those things worse than they already are?

      Every technology has its limits, and the anonymity is actually pretty good. When you browse with TOR, you do these things:

      • Prevent anyone between your computer and TOR from discovering what data is being transferred. In this case it's the university.
      • Prevent anyone between your computer and TOR from discovering the destination of the data.
      • Prevent the recipient of the data (whoever you are connecting to) from discovering its source (who/where you are).

      The university can see that something went between TOR and one of their computers, but they have no idea what that something is or where it's going. Since anyone who can get access to a computer can use it, the university actually doesn't know who was using the computer. They can only guess because it belongs to that professor and is in his office.

      If the professor had taken an extra precaution and used a computer that was not linked to his identity, there really would have been no way to catch him unless they ran over to the machine while he was on it. If were truly a sneaky bastard, he would have installed TOR along with a program to activate it and do some communications and left before it went on. At some later time he could come back to that machine briefly just to retrieve the data.

      If you are in a repressive country, you could start by using TOR discretely at an internet cafe. As long as the managers of the cafe are not actively policing their clients, you won't get caught. Better still, your government has no clue and will mistake TOR for traffic they're not interested in.

    It was debated because well... what if someone had a legitimate acedemic need to recieve viruses in email?

    Seriously! We gave unfettered internet access. Porn? Well... guess what... someone may be doing acedemic research into porn and needs to access porn sites. These are legitimate debates that come up in that environment because... they take the persuit of intellectual inquery as serious buisness... because it IS their buisness.

    No firewalls, no filtering... unfettered access, because if someone needs it, they need it.

    There were 2 requests made to him. The first is not objectionable, the second is highly objectionable.

    First: please stop using Tor on our network. Not very objectionable, they do own it and can request that sort of thing. Kind of like saying "please don't seed torrents of 20 Linux CD images on our network."

    Second: please do not tell your class about Tor even though you believe it is relevant to what they are learning about. This is highly objectionable, and undermines the purpose of the university as a place for free exchange of ideas. Even assuming the university is private and can tell him to do this, they shouldn't tell him to do this. It makes them a worse university. Can do and should do are different questions.

  8. VPN, Proxies, etc... by Ohio+Calvinist · · Score: 3, Interesting

    I used to work for a large Midwestern University, and we blocked outgoing connections to some services, such as VPNs and some proxies. The reason we did this was during the outbreak of the virus (can't remember the name), that hammered Windows on Port 135, we blocked incoming Port 135 connections at the University border. It was hypothesized that if users VPNed to other networks, they would circumvent the port block and become a vector.

    I know everyone worth their weight in IT realizes that a secure border isn't enough. We had virus protection available for free for every seat on campus, however, in a huge distributed environment (where departments and colleges were "islands" in a network ocean, with their own IT staff) we couldn't gaurantee the integrity of these machines. But we were sure going to be the ones to take the hit when their "nice kid that they liked to much to see them move on after graduation system admin" didn't bother to CHECK to see if the definitions his AD-out-the-box for dummies was pushing those defs.

    We also disallowed some of these services because it became harder to effectively monitor our network. When some s5r1pt k1dd13 in CIS 201 decides that he is now a UNIX god is and is going to put "Bush Sucks - $college_name is #1, fark $rival" on whitehouse.gov to impress his pink haired, pot smoking, PETA member across the hall in the dorms who only talks to him when he removes the spyware she got trying to download off KaZaa, we look like complete dickheads when the Feds show up (or the **AA) and the best we can do is say "I don't know... what goes on in them there tubes" the suits tend to get pretty agrivated.

    On the other hand, even if they are SSHing into an intermediary (which we strongly encouraged over telnet), we can at least say "Well, we had an outgoing SSH connection from 4 machines on campus at that time going to these 4 addresses, do any of those ring a bell? We happened to have authenticated WPA, so we can tell you who these folks are even if the machine name is PoPPySeeD420 and done from the student union.

    Privacy is wonderful, but when the shit hits the proverbal fan, IT would like to know who is pulling shenanagins on the network. The rest of the time, 99.9999% of the time, we'd rather NOT know what you're up to, and every one of us in the office (except for that one windows fanboi MS office specialist who we used to throw beanbags at) had our open source/linux/free as in beer and freedom/crypto-privacy street cred.

Not only that, the person using the service remotely is unrelated to the host that shows up in the logs... It's a drop-in backdoor tool. Instant access to the internal network.

    I missed the sarcasm too. I guess too dry for me.

    Here's the deal-- you cannot have unlimited medical coverage.

    Period.

    1) there are too many diseases that can be cured IF you have unlimited resources... well really about $2,000,000 to $10,000,000 or so. The point is- we can't afford to cure everyone's $350,000 bypass surgery so we let people pay for it themselves or die. You do it in canada too- you just do it via rationing and delays instead of via money. "Sure you can get your surgery-- in 17 months" vs "Sure you can get your surgery- for $350,000".

    2) If we could get the legal $ystem out of it, the costs would be much lower but there would be more malpractice. We currently say "no mistakes and no malpractice" but that decision probably doubles or triples every thing we do medically. Which in some cases means that the procedure that could be done cheaply- is now too expensive.

    3) Even in socialist countries- you are paying. Sure- you may rip off the doctors (with a resulting shortage of doctors and hence long wait periods) but the drug company executives are still flying around in jets and vacationing in maui.

    So the point is not curing every illness known regardless of price- but setting a reasonable amount of tax dollars aside to cover a reasonable amount of medical expenses for the most people possible. No open heart surgery for 98 year olds on the tax dollar but if they want to pay for it themselves- okay. Yes to vaccinations for everyone and broken limbs (tho perhaps a limit on the number of times to reign in the reckless types).

Even staff - supervising staff is their manager's job, not the responsibility of the IT group. If he was sharing his password and outside folks were crowding up the terminal server, or he was running a warez site, sure. But this?

Sure, it might be for their research, but that doesn't matter in that case. It's a shared resource, there's a limited (by the University) budget, and it's not an academic freedom issue. It might be convenient for one of the physics faculty to have a supercollider as well, but it's not in the University's budget. You have to partner with someone outside, or get grants, etc. Every instituation has limits and priorities.


    But this? This is bizarre. The only awkward situation I can think of in some states is that state schools can fall under open records laws that require that the public can check on certain information (in some states, browser histories have come up in the past). In that case, as a state employee, they might be violating the open records law by going out of their way to hide their activity. Hell, even under a Patriot Act search, we'd have to give them whatever information we had about a user, but we're not obligated to keep information to track back every outbound internet connection - even under CALEA.
