[Air-l] metaphors for internet security

[jeremy hunsinger]

I was thinking today about what metaphors might be appropriate for 
internet security.  I was considering primarily metaphors based on 
current technology.  If you had to think that the internet security was 
most like a the security issues surrounding another technology, would 
you think that it was more like keeping a house secure, or a wallet?  a 
car secure or a toaster secure?  thoughts?  other ideas?
