Programa que está diseñado para copiarse y
propagarse por sí mismo mediante mecanismos de red. No realizan infecciones a
otros programas o ficheros. [CCN-STIC-430:2006]
Programa que puede autoaplicarse y enviar copias de
si mismo de un ordenador a otro de una red. Tras su instalación en uno de éstos
repite el proceso anterior, además de
realizar alguna otra tarea indeseable, quizás hasta colapsar el sistema
anfitrión. [Ribagorda:1997]
Es un programa similar a un virus que se diferencia
de éste en su forma de realizar las infecciones. Mientras que los virus
intentan infectar a otros programas copiándose dentro de ellos, los gusanos
realizan copias de ellos mismos, infectan a otros ordenadores y se propagan
automáticamente en una red independientemente de la acción humana.

Malware that is able to copy
itself from one computer to another, unlike a virus that relies on embedding in
another application in order to propagate itself from one computer to another.
The Tallinn Manual, 2013
A self-replicating, self-propagating, self-contained program that uses
networking mechanisms to spread itself. See malicious code. [CNSSI_4009:2010]
(I) A computer program that
can run independently, can propagate a complete working version of itself onto
other hosts on a network, and may consume system resources destructively. (See:
mobile code, Morris Worm, virus.) [RFC4949:2007]
A self-replicating program
that is completely self-contained and self-propagating. [NIST-SP800-83:2005]
A self-replicating,
self-propagating, self-contained program that uses networking mechanisms to
spread itself. [NIST-SP800-61:2004]
A computer program that can
run independently, can propagate a complete working version of itself onto other
hosts on a network, and may consume computer resources destructively.

A program that can replicate
and send itself between computer systems. A worm can cause damage by itself or
act as a delivery agent for a virus.
http://www.csoonline.com/glossary/
A worm is a program that
makes and facilitates the distribution of copies of itself; for example, from
one disk drive to another, or by copying itself using email or another
transport mechanism. The worm may do damage and compromise the security of the
computer. It may arrive via exploitation of a system vulnerability or by
clicking on an infected e-mail.

Un ver est un logiciel
très similaire à un virus. Cependant et contrairement au virus, un ver n'a ni
besoin de l'intervention humaine, ni d'un programme hôte pour infecter une
machine. Il dispose de son propre moteur, un automatisme qui lui permet de délivrer
et d'exécuter automatiquement son code, comme par exemple un mini serveur de
mail lui permettant de transmettre une copie de son code par e-mail, puis, par
la suite, de chercher des nouvelles cibles à infecter.
