Backdoors

A backdoor (also known as a trap door or wormhole) in a computer system is a method of bypassing normal authentication, securing remote access to a computer, obtaining access to plaintext while attempting to remain undetected. This backdoor may take the form of an installed program (e.g. Back Orifice) or could be a modification to an existing program or hardware device.

A backdoor in a login system might take the form of a hard coded user and password combination which gives access to the system. It should be stated, however, that the motivation for such holes in the security of a system is not always sinister; some operating systems, for example, come out of the box with privileged accounts intended for use by field service technicians or the vendor’s maintenance programmers.
