= B =
[common among security specialists] A
cracker, someone bent on breaking into the system you are
protecting. Oppose the less comon `white hat' for an ally or
friendly security specialist; the term `gray hat' is in
occasional use for people with cracker skills operating within the
law, e.g. in doing security evaluations. All three terms derive
from the dress code of formulaic Westerns, in which bad guys wore
black hats and good guys white ones.
