Interesting topic

You've actually touched on one of my areas of interest. As you know, I've spent many years working with computers in medicine, but, especially in security and reliability, I've had personal interests in applying biomedical concepts to computer networks.

When the first Internet worm propagated in (umm) 1987?, I watched a lot of very smart people running around reinventing a number of concepts of epidemiology. At one point, I asked one of the best security people around if he had considered the work of John Snow, and got the response of "who?"

If you look at Virtual Router Redundancy Protocol, one familiar with both can imagine the backup router acting as an AV node backing up the SA node. I've applied epidemiological contact tracing principles to try to look for the patterns characteristic of secondary infection, of multiple infection sources, etc., but gotten relatively little interest. A few network security engineers think of "quarantine", most commonly citing SARS, but don't go into anything like the hierarchy of immunologic responses. Yet, I see parallels in the way we deal initially with distributed denial of service and a nonspecific macrophage response, while we divert the suspicious flow to analysis and start to develop the equivalent of immunoglobulins (e.g., blackhole routes). Too bad I can't find anyone interested in sponsoring an interdisciplinary team in this area. --Howard C. Berkowitz 05:09, 12 January 2010 (UTC)

Wow! "...applying biomedical concepts to computer networks..." If you could give every computer on the network a sophisticated effective immune system, with Darwinian evolution built in, you'd get a ticket to Stockholm.

I started Biological networks while reading Dennis Bray's Wetware: A Computer in Every Cell. I'd played with bionets in working on Systems biology. There I cited:

I also wrote about bionets in Life and further in mLife/Draft. Seemed like biological networks merited its own article. Anthony.Sebastian 03:00, 13 January 2010 (UTC)

The line blurs

As man-machine interfaces get more intuitive, as well as machine-machine, it gets interesting in drawing the line. If one looks, for example, of mobile ad hoc networking, I'm at least vaguely reminded of a local inflammatory/immune response, with automatic failover of dead or migrated cells. It's one thing to think of telescopes, radars, and other sensors that increase range, but the soldier-level local area network, as in the intra-squad radio, is what I might call "connectionist" evolution.

To turn it around, it's easier to turn off an electronic network than a biological one. I can see evolutionary reasons for the autonomic response to pain that causes prostaglandin release and stiffness, but I'm not sure if that's as adaptive as when we were in caves. A lot of modern electronic networking is filtering, removing artifacts, and eventually majority vendor logic.

Again this may be getting too far afield, but consider the analogies between brain fusion of multiple sources, Blue Force Tracker, and the common operational picture. There are classes of instrumentation such as network intrusion detection systems which, arguably, send somewhat processed antigens for amplification. Howard C. Berkowitz 05:22, 14 January 2010 (UTC)
