The healing's pretty simple, it builds off the protection mechanism. It's sort of... turning it around? But not in the same way as the opt-out thing Sara-chan was talking about a while back. It's more retroactive.

Getting infiltrators on the network... is considerably more complex. As far as I can tell, it's along the same lines as putting an animal companion on the network, but you have to push a little harder to get through to an infiltrator.
