Behind the Scenes at MIT's Network

BobB writes "MIT's head of computer networks and security gives an inside look at how the techie school is fending off hackers, cranking up its network to handle voice over IP and become a fiber network operator to link to other research institutions. From the article: 'Q - How do you actually enforce security standards among MIT's departments and network users? A - Enforce is not a word you can use at MIT. We try to entice people to do the right thing. We've made a lot of progress. We've removed the financial incentive to run your own network, which used to be cheaper than having us do it. We've been a cost-recovery network since forever now though. At many universities the network is free and they just fund it out of operating costs.'"

      Plymouth University isn't small (about 30000 students enroled) because of the cost of notes the IT department modifed MS Exchange and started putting all lecture material online. Plymouth University also has 6 smaller campuses all of which can access this network (wirelessly on their campuses) there was a major network failure for the first time recently (A recently bought batch of Hard Drives failed badly in the SAN taking most of it out two days before the christmas break, by the end of the next day most of the network was working bar personal account space and personal email) by the new year (a week and a half after the failure) the full list of services were running as far as I've been able to make out only emails sent the night of the failure were lost (it happened at 7PM.) Since all external connections go through the Uni's VPN its also pretty secure.

      Now this is for a university which is primarily a humanties university, why is a technology university only now looking at providing wireless access for laptops and PDA's when some have been doing it for five years?

    The cool thing about MIT is that they own the entire 18.0.0.0/8 Class A address space, so every device on campus has a public IP.

    And all computers (even student machines) are connected directly to the Internet - no NAT, no firewall, no protocol limitations, no bandwidth caps.

    The catch is that all computers need to have a registered MAC address in order to get on the network, so if your Windows machine gets infected with a virus, they can disconnect you in a hurry.

      Penn State issued a public IP for every machine connected to their network. It still may be so. Before Napster came down, I hosted my music collection, amongst other things, on the Internet via FTP.

      In my time there, they did not, however, actively monitor systems for viruses and malware. I often received spam from student PCs attempting to spread viruses via attachments. Many lab systems suffered from various malware, although that improved in my last year after they switched to a pseudo-thin client setup.

      Today, I see such IP allocations as wasteful. The worst is a power utility which I worked for a few years back. They have (had) a direct allocation (can not recall the exact size), which they used of course for business purposes. However, they also assigned public IPs to devices never exposed to the Internet, i.e PLC controllers and process control computers. Most unfortunate IMHO.

  7. It happens, but not "standard." by Kadin2048 · · Score: 4, Informative

    It's not "standard," but there are places that do it. Generally small campuses, or ones that didn't build-out wired infrastructure when they should have, and are now trying to catch up and be 'wired' using 802.11 as a substitute for a real copper network.

    I know there are quite a few schools deploying it strategically, which seems like a good plan. It only takes a few minutes walking around a college campus to realize that there are a few key places where wireless would be most useful, and a lot of places where it would probably be underutilized. Libraries are huge -- go into any uni library and you'll see rows of people typing away on laptops. If you can't afford to put an Ethernet drop at every study carroll, wireless is the next best thing. (Well, actually, both would be best.) Study lounges and communal spaces are probably next, followed by cafeterias and big lecture halls (if you want to encourage people to use laptops in class; some schools might have faculty that would rather discourage that). In warm climates, outdoor locations can be great locations for Wifi, too.

    But deploying it all over a large campus would, for most schools, be impractical. It would take too many base stations and would cost too much for the number of users you'd probably have at a time on most of them. I think if you did roll it out everywhere, you'd probably find pretty quickly that some nodes took huge amounts of load, while others were basically never used. For this reason, most large places with a competent IT staff don't just shotgun it all over campus, but are more selective.
