[Deadbolt?] Security with non-vanilla chests

Last night I built an applied energistics storage system, which I am finding to be an impressive large-scale storage solution. I moved over 20 double chests (full of items) into a 2x2 computer terminal. I'm excited about the possibilities for expansion, but I'm worried about security.

How do I protect my AE storage units from theft or (more likely) accidents caused by other players?
Also, can I lock or restrict the Access Terminals and Wireless Access Points?
Can another player simply place a wireless terminal outside my house and access all of my stuff?
Can anyone recommend a destruction-proof, theft-proof storage solution for my valuables?

I know this server is on a whitelist, but I'd rather not leave a giant temptation for other people. I'd also like to share certain things with other players - without tempting them with my jewels.

I am considering add grief prevention to the list of plugins. Either that or take advantage of world gaurds claim system. With world guard you can prevent people from entering your region. Not sure if grief prevention does that as well. But it might help a lot.
