security through obscurity
(alt.: security by obscurity ) A term applied by hackers to most OS vendors'
favorite way of coping with security holes namely, ignoring them,
documenting neither any known holes nor the underlying security algorithms,
trusting that nobody will find out about them and that people who do find
out about them won't exploit them. This strategy never works for long and
occasionally sets the world up for debacles like the RTM worm of 1988 (see
Great Worm ), but once the brief moments of panic created by such events
subside most vendors are all too willing to turn over and go back to sleep.
After all, actually fixing the bugs would siphon off the resources needed to
implement the next user-interface frill on marketing's wish list and
besides, if they started fixing security bugs customers might begin to
expect it and imagine that their warranties of merchantability gave them
some sort of right to a system with fewer holes in it than a shotgunned
Swiss cheese, and then where would we be? Historical note: There are
conflicting stories about the origin of this term. It has been claimed that
it was first used in the Usenet newsgroup comp.sys.apollo during a campaign
to get HP/Apollo to fix security problems in its Unix- clone Aegis/DomainOS
(they didn't change a thing). ITS fans, on the other hand, say it was coined
years earlier in opposition to the incredibly paranoid Multics people down
the hall, for whom security was everything. In the ITS culture it referred
to (1) the fact that by the time a tourist figured out how to make trouble
he'd generally gotten over the urge to make it, because he felt part of the
community; and (2) (self-mockingly) the poor coverage of the documentation
and obscurity of many commands. One instance of deliberate security through
obscurity is recorded; the command to allow patching the running ITS system
(escape escape control-R) echoed as $$^D. If you actually typed alt alt ^D,
that set a flag that would prevent patching the system even if you later got
it right.
