UC Berkeley Cleaning up its Security Act 79

Bob Brown writes "UC Berkeley recently issued a scathing self-assessment of its IT department, which has been under fire in the wake of a couple of high profile security lapses at the school. NetworkWorld has a review of what the school's top networking guy says is being done to both secure and strengthen UC Berkeley's computer networks."

  • Obviously they haven't been rotating their passwords frequently enough, just force everyone to change theirs every three weeks and all security problems will be solved!

        It sounds like you might be making a joke about this one but at my university (University of Warwick, uk) they had the worlds most lax attitude to security it was insane. There were several huge security leaks and no one seemed to question why they weren't using and changing secure passwords... someone script kiddie broke into the main server (taking all of our private info stored on it) using nothing more than a simple brute force crack... it gave in so easily because they'd used a word from a standard dictionary... I figure it would have taken no more than 60 seconds to get in. The moral of this and the UC Berkeley story is this; don't trust a university IT dept with any of your private information, store nothing on their computers, use a different password for the log on there and for everything else (if you insist on using the same one everywhere)
        • That's ridiculous.

          I had heard bad stories about the IT provision at Warwick (particuarly their Resnet service), but didn't realise it was that bad.

          Here at Bristol, I've worked for our Resnet over the summer, which is housed along with the IT guys. Security is absolutely paramount, and even for little Resnet projects, we would sit down for a couple of hours for a threat assessment (SQL injection, what happens if a dictionary attack succeeds, could we place exponential back-off on the login page).

          That said, t

          Doesn't that mean I can't go to college? I'm not worried about some warez monkey stealing my physics paper off the shared drive, I'm worried about them breaking into the bursar server and getting my SSN, bank account details, credit card number, etc. Colleges have no reason to clean up their act in that respect because it doesn't hurt them in the least if *your* security is compromis
      • "You'll end up with cycling passwords of "hello" and "password" every three weeks."

        There needs to be a "whoosh" mod category. Can you guys at slashdot get working on that?

        Grandparent knows that the password rotation scheme is common practice in *many* environments, and was pointing out the uselessness of such a strategy. It's called "illustrating absurdity with absurdity"
        • Where I work currently, the network saves my last 27 passwords. New passwords cannot be in that list, and are checked for similarity to those passwords. A certain number of characters must be different, and not just switched around ("password" v. "apssowdr"). Users cannot just cycle through passwords, there is a minimum and a maxmimum age.

          • If they're saving your password in a format where they can easily tell if your new password is some permutation of the characters in the original password (i.e., they're either storing the original password as plaintext or in a format that they can easily decrypt to check for permutations, rather than using a one-way hash function), then they're sacrificing actual security for the illusion of security. Nice.
            • Alternately (and far more likely), they're comparing permutations of your *new* password against the old hash. They're not recovering plaintext for the old password, but using the plaintext of the new password to create the permutations. See pam_passwdqc for an example of this technique, or npasswd. Most password checking systems will do this.

            • They could be saving the hashes of the old passwords.

              Step 1. Once the new password is entered, you hash it, check against the list of saved hashes to see if that exact phrase had been used already. If so, deny new password, if not, move to step 2.

              Step 2. Take the plain text of the new password that was entered, re-arrange and/or substitue some characters (E.G. "password" becomes "asswordp"), generate a hash of this value and check against the old saved hashes. If the new hash matches one in the lis
              • I stand corrected. On the other hand, I think I was right in saying that you can't do it "easily", as the system you descibe is going to require checking a lot of permutations one by one instead of coming up with some quick fuzzy check of similarity. I guess if you've got the processing power to do it, that's a good solution to the problem.
                • You're right, it wouldn't be easy or straight forward. The logic as to what combinations and permutations of the password to test and how many iterations to do so would be a PITA. It would also probably be overkill for most systems.
            • As other posters mentioned there are ways around this, but still, it is focusing on the wrong area. There are much more productive ways to spend time increasing security than pissing and moaning about reusing a password several years old. 27 passwords at 3 months per password is almost 7 years. Who cares? Try dual authentication, better passwords to begin with, and better security over the network itself (e.g. encrypting traffic).

        • *whoosh*, indeed -- I'm almost certain great grandparent was actually referring to this specific story [slashdot.org], rather than illustrating absurdity with absurdity.
      • Oh we'll make it so that you can't use old passwords again, either.

        Instead, you'll have to do: password, hello, password1, hello1, password2, hello2 ...

        You laugh, but I've been there.

    Berkeley UNIX (the original BSD) was full of security holes. It shipped with such beauties like being able to get a shell by typing the right command at the SMTP server and multiple buffer overflow bugs in just about every server and command line program. And many people knew about it, both at Berkeley and elsewhere, but nobody cared much until the Morris worm. Apparently, while the world has moved forward, Berkeley still isn't taking security all that seriously.

Well, then you know what to do next, right: Leave crack running on the file on the old Sun 3 in the corner and some day or days later we would have a stack of accounts. Most of them were cracked with dictionary words. Too easy.

    It takes educating users. So far I haven't experienced resistance to education, but the amount we have to do is pretty staggering.

    The issue is not about educating the professors and staff. Most everyone will happily participate. The issue is getting them to actually change their practices once they've been through the education. You need education, then support for the education, then regular audits about the education, then some more education.

    FTA: ...the department has Smart Dust - tiny sensors that run TinyOS and TinyDB. They scatter this stuff out there - put it in trees, on animals - they're all networked together and people monitor them. That's different than [managing] a connection in every office.

    I dunno, I'm pretty sure some of my past employers spend their days hanging from trees, or on animals... even in the office.

    The article, sadly, doesn't push on finding out why people were carrying around laptops full of sensitive information.

    Why did they need it? "Oh, I'll just download an Excel file of every students personal details so I can make that Powerpoint presentation I want!" Why weren't they using some method of protecting the student's data at all? If I had access to data like that, I would only expect to get it on-demand from a server across a secure VPN with a tough password (SecurID perhaps).

    I don't understand why you would want such information downloaded unless you were going to do something malicious. Could someone explain to me why these people were just walking out the doors with entire databases in their rucksacks?
    • A list of all of the students is commonly used to prepare reports required by the Department of Education (google IPEDS), providing data for college guides (we do about 50 per year), and surveys from professional organizations (e.g. Engineering Workforce Commission) However, the first thing you do with a file like that is to delete the following columns: Social Security Number, Names, Phone Numbers, Next of Kin data, and Addresses (except perhaps Country or State of Origin).

    • Under FERPA, even a name and a grade for a paper is federally-protected private data. So, if you have a spreadsheet with the scores from the last quiz, that's sensitive, personal data about students that triggers those laws. It isn't necessarily SSNs and CC#s. Hell, under FERPA, even the names of students in a class can be protected if one student has preferred to have their directory info suppressed.

    • I know your joking, but in all seriousness, your security should never depend on not disclosing your strategy. If it does, something's wrong.

      Pretty much anybody in IT can tell you what the "best practices" are, there's nothing secret about them, and a good implementation doesn't depend on the attacker not knowing what they are.

    You'd think that since BSD comes from Berkeley, it should be a popular OS on campus... Think again. Everyone's #1 choice is: Windows XP.

    You go to a (non-CS) computer lab. You login with your SID and password. A new Administrator account is created for you. Go ahead, do whatever you want - when you logout, all your files will be deleted, and everything will be restored to the original state. Completely secure, until you realize... "Duh. I have an administrator account. Why can't I just prevent the computer from restoring everything on logout?".

    I reported this to one of the lab workers, and even demonstrated: she logged into her own account, but the desktop background picture said in big red letters, "Caution: This system has been haxx0red". She was pretty shocked, and said she would inform the system administrators.

    This was half a year ago... Nothing has changed.

    The CS labs are different, though. They run Solaris 9. Security shouldn't be a problem here. Usability is, though. How many of you guys remember what Gnome 2.0 looks like? How about Acrobat Reader 4? I do, unfortunately. And the Slashdot jokes about "^H" suddenly made so much sense...
    • Yeah, the Sun stuff is amusingly out of date. Should note that most of the EE computer labs are Windows machines, though they're locked up in terms of account permissions. Also, the inst.eecs webspace gets ddos-ed every so often.
