Greek Hackers Target CERN's LHC

Doomsayers Delight writes "The Telegraph reports that Greek hackers were able to gain momentary access to a CERN computer system of the Large Hadron Collider (LHC) while the first particles were zipping around the particle accelerator on September 10th. 'Scientists working at CERN, the organization that runs the vast smasher, were worried about what the hackers could do because they were "one step away" from the computer control system of one of the huge detectors of the machine, a vast magnet that weighs 12,500 tons, measuring around 21 meters in length and 15 meters wide/high. If they had hacked into a second computer network, they could have turned off parts of the vast detector and, said the insider, "it is hard enough to make these things work if no one is messing with it."'"

      You're correct (I did an internship recently on data management with the LCG/EGEE network). It's a massive multi-tiered network of datacenters (something like 50k nodes, 15PB of dedicated data storage, but don't quote me on these figures), all required to distribute the enormous amounts of data collected in the experiments to the researchers capable of processing the data.

      I'm not going to be an ass and piss too much on the work of thousands of others, because it took quite a bit of effort to set this up, but them getting hacked doesn't really surprise me. The architecture they set up (even for only data-distribution) is very complex, and a lot of software they use has been written in-house or has been forked (years ago). Oh, and it's all open source, readily available for whoever looks for it. With the LHC being such a high-profile target, this is IMHO a security nightmare waiting to happen.

      In what I've seen, I'm crossing my fingers that this break-in isn't related to the grid network, and that the next few months will go smoothly, but the grid has been primarily designed for high throughput, not security.

ShibGrid doesn't care if it's securing a particle accelerator or a wide-area distributed MMORPG, but I bet you anything that if WoW was a part of the Grid Gaming consortium, ShibGrid would be more audited than OpenBSD by more anal coders than Theo ever thought of being. There may be only one LHC, but anybody can run a Globus module through a static code checker and fix "obvious" coding errors.

      True, the LHC has limited staff and can't check every patch people send to them. But the same problem is faced by OpenBSD, Linux, X.Org, the GCC developers, and a thousand and one other mega-coding projects. They seem to solve the problem without too much strain, so what do they do that the LHC guys aren't? I don't have to be a genius to solve the LHC's security issues, I merely have to know where the geniuses are and see what they do different.

      Also true, the size of the code base makes the idea of bug-free code laughable. The middleware alone is HUGE. However, that's deceptive. There's a fascinating paper on Trusted Software. Not "trustworthy", "Trusted". As in A1 Orange Book Trusted. The paper basically states that buggy software is not the issue. So long as you have a small, tightly-written security kernel within key components, where that security kernel can be proven correct, bugs elsewhere can never pose a security risk. They can do lots of other nasty things, but they can never compromise the security of the system.

      As the paper in question (which I've linked to previously, on the issue of security) is written by one of those aforementioned geniuses, and as this is something those geniuses do differently, it follows that this is a factor in what makes the difference between secure software and insecure software. MPI, a common message-passing system, usually uses RSH to start applications across a cluster or grid. Since MPI is generally not going to have any means of providing passwords, this means you're looking at .rhosts files, which means you've a wide-open security hole right there. And, yes, having worked at such facilities I can tell you that they often don't use SSH or a Kerberos-hardened RSH, just the vanilla form that no sane person would use in a million years. (This goes to show that, yes, scientists truly are mad.)

    I've never worked at CERN, but it may be similar to large-scale science user facilities (e.g. x-ray synchrotrons) that I have worked at. Specifically, you want to be able to control the instruments remotely for a variety of reasons. Part of it is safety (in order to minimize time spent near radiation sources and industrial equipment). Part of it is convenience (to check on the status before driving all the way to the actual facility). Part of it is for collaboration (allowing an instrument scientist to log into the machine and change a setting for you, show you how to do something, etc.).

    At many facilities, you can change samples, alter instrument settings, re-align, etc.; all without actually going to the facility. Scientists doing those kinds of experiments do indeed appreciate the ability to log into the machine at 1am and check on the status.

    There are of course safeguards in place (e.g. hardware safety triggers that cannot be remotely over-ridden)... but it is sometimes possible to break something with remote commands. Now, most of the facilities that work like this are running samples, and need remote manipulation to switch samples and re-align and so forth. LHC doesn't have the same set of requirements... but there are indeed a variety of legitimate reasons why a scientist might need to remotely log into the system and change some settings.

    Large facilities are designed to "do science" 24/7. Remote control is one thing that helps scientists maximize the usefulness of equipment. (Such as waking up at 1 am, checking on an experiment you started before leaving work, realizing the data is no good, fixing a few parameters, and running a new more useful experiment.)
