Unless you have a different definition of securing it, that usually includes taking control interfaces off the web. However, as I argued elsewhere, Setting this up so that data flows out of the network, with no option of getting a resend on packets means no verification.

Would you like to be the person who points out that the packet with the higgs boson failed checksum, and the network was set up so you can't get a reply to a resend?

Don't forget - there's a lot of radiation around the LHC, and random bits could well be flipped in transmission.
