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.
