Genome Methods Applied to Reverse-Engineering

L1TH10N writes "Wired news has an article on a truely innovative way of analysing network protocol reverse-engineering. Marshall Beddoe, a security analyst, is using algorithms used in bioinformatics to analyse closed-source and secret network protocols which he calls "Protocol Informatics".According to Beddoe, network conversations are full of "junk" -- usually the actual data being sent -- which interferes with the analysis of the occasional command sequence that controls what to do with that junk. This has parrallels with Bioinformatics that has to deal with a similar problem of finding known DNA sequences separated by long gaps of unknown data. Biologists have devised complex algorithms to discover whether DNA sequences are descended from the same ancestors by comparing the genetic differences with the known mutation rates of certain DNA components. Beddoe applied the same principles to mutating network conversations of evolving network protocols."

  5. Contrasts: Datastreams to DNA by w.p.richardson · · Score: 4, Insightful
    "Junk" in the datastream is useful (since we have made it, we use the control codes to reassemble).

    "Junk" in DNA (e.g., "latent" DNA) is probably not junk, we just don't know the function (yet). No scientist worth their salt would admit that (at least not in earshot of a grant proposal review committee!)

  6. Network Protocols vs. Building Blocks of Life by Sheepdot · · Score: 5, Insightful

    That'll come as a relief to Beddoe, who until now assumed that biologists wouldn't pay much heed to his project.

    "They're working on uncovering the mysteries of life itself; we're just hacking network protocols," he said. "Which sounds more important to you?"


    I don't think Beddoe should cheapen the reverse engineering aspects of networking compared to biology. We may still be years away from finding a cure to cancer, AIDs, etc. and there's a good chance that biology work in this area might not be as fruitful. After all, (without getting into a religious debate, here) man was not created by man, whereas network protocols are. Because of this, it is relatively easier for us to reverse-engineer something that was created by another human, because we know how they think. Evolution or creation, we don't know much about our own building blocks, because we don't know how either God thinks, or the universe fully works.

    While his software is great for "hacking network protocols", the biologists paying attention to his work might not find what they are looking for. The inputs very well may be just too vast for his ideas to provide any help.

    On the other hand, the Samba team and the Spam Assasin author will most likely enjoy this.

    "The problem of decoding the language of networks and the problem of finding signals in DNA are really two related instances of machine learning problems. We're almost bound to discover universal principles of information communication by investigating both," - Terry Gaasterland
    This seems like a pretty obvious conclusion after reading the article but I'm curious why there aren't any reference's to pure informatics studies. Is there such a thing? After initial googling I'm only seeing bio-informatics results. Anyone have any insights as to what I should be looking for to find research/papers/studies on pure informatics or "universal principles of information communication".

  9. Bioinformatics links by mattr · · Score: 4, Informative
    Yesterday wrapped up over a week of intense Bioinformatics seminars, poster sessions, exhibitions, and brainbusting studying at Bio Japan in Tokyo and related links. I just saw a presentation on the H-Invitational database which though in Japan also combines the content of foreign databases. It is extremely impressive, and they combine lots of online calculators and results visualizers that are really impressive.

    Also figuring out biology seems to be a lot harder than figuring out networking, at least there are all kinds of nefarious things but also serendipitous things found. Like one presentation I just heard had a U.S. scientist who announced that they had discovered an entire signalling network in human cells that was like the one found in yeast cells. And apparently more proteins can be encoded than the number of genes, because of alternate orderings (counting from different displacements in the gene, I think, ask a real bioinformatics expert). One talk I heard a year ago that stuck with me was a scientist who had devised a way to find signalling pathways in cells quickly; by forcing the cell to die if certain requirements were not met, he created a parallel computer that allowed him to discover a whole swath at once. There is also a lot of math and statistics, as well as a lot of biological knowledge behind it, it is not strange to see various statistical tests, references to different computer programs they used for analysis, or a mention of simulated annealing (well maybe that one not so often, came up yesterday though).

    One interesting thing is that they (the H-Invitational people / Japan Bioinformatics Consortium) have I believe twice held what they call annotation jamborees, much like a hackfest! In 2002 they had 120 scientists gather (mostly Japan but from all over the world) in a big room with a computer per person. They locked them in for 10 days, and annotated IIRC over 20,000 genes, basically doing a figure some man years of work in a week, inputting data so it can be searched, analyzed, and crossreferenced.

    They do have a comparison between mouse and human genome there, I wonder if something similar could be done in open source in terms of annotating and indexing a libary of open source code in different languages, really all in one pseudo language would be more useful perhaps. Anyway biologists are learning from computer scientists learning from mathematicians, and someone famous has said that in the future, all science will be computer science.

    Bioinformatics people are doing text mining and data mining, but also there are many flavors and types of analysis programs designed to penetrate and match up information as encoded by tiny molecules, folded proteins, genes, and so on. Here are some links to get started. Also note the perl for bioinformatics books, and there was a big oreilly bioinformatics conference archived from 2003 and other links too (see bio.oreilly.org link below).

    I cannot speak for everyone, but I can convey what I have heard, that there have long been communication gaps that have held back some of this, actually cultural differences. For example physicists like pure math and biologists deal in dirty, wet things.. when people successfully combine different perspectives in this area [more] discoveries start getting made. In Japan at least they are trying to figure out how to grow more bioinformaticists, since students tend to go only towards either biology or towards computer science (why study twice as hard). But there seems to be a lot of interesting stuff in there for both sides.

      Actually, the increase in number of genes compared to actual encoded genes as you move up the "eukaryotic evolutionary chain" is due to the organisms finding new and novel ways to combine the same protiens.. not in different displacements of the same gene.

    I work right in the middle of all that is biology at MIT(Center for Cancer Research, Biology, BioInformatics, Chemistry, Biological Engineering, Brain and Cog, Mathematics, Physics, Computer Science, etc..) and the geeks in each department are aware of the advancements made in other departments and how they can help themselves. In fact, MIT created something called CSBi, the Computational and Systems Biology Initiative(csbi.mit.edu), which has professors and students from all the departments listed above, and more. They collaborate, share students and projects, organize retreats and conferences. There's even a degree program in systems biology.

    The majority of study is computer research applied towards biological methods and models, but I'm sure some of the cs geeks will be reading this article and grab the work done by the bio geeks.

    And in the end, we will all have the best mouse trap ever.
