Trojan horses

[jbn at wdl1.UUCP]

       The term ``Trojan Horse'' is used by the computer security community
to indicate a device or program deliberately placed inside a security 
perimeter which, acting in concert with an attacker outside the security 
perimeter, allows a specific type of attack to be successful where it would
otherwise fail.  Note the use of the word ``deliberately''.  Gaps in security
occuring through error or ommission are not considered Trojan Horses.
       The term ``Trojan Horse'' is generally considered to come from Homer's
description of the siege of Troy in the Illiad, of course.
