We would not! :-) We would say "What is your security policy? Is that
information world readable?" and "What is the strength of your
security system? Is it easy enough to spoof so that it doesn't
matter?". Since tcp addresses are spoofable anyway, making security
less friendly is only encouraging people to work around it, which
makes it less secure. User-friendly security _is_ better security.

Only if you've got a Mandatory Access Control policy, that mandates
that folks with a Confidential clearance can't know the names of Top
Secret files, since their names are Top Secret too. Anybody with this
policy isn't using the standard WWW security mechanisms :-).

An anal security (and usability) fiend,
