A back door is a software program or set of related programs that allows access to a system without going through the normal log-on procedures. It is often intentionally installed by system administrators as a means for accessing the system in case of emergency or for maintenance purposes, but can also be installed maliciously by attackers to gain unauthorized access to a system. Logic bombs, Trojan horses, and worms are all types of malicious software that can be used to gain unauthorized access to a system or cause harm in other ways.
