VPN

Acrónimo de “virtual private network” (red privada virtual). Una red informática donde algunas conexiones son circuitos virtuales dentro de redes más extensas, como Internet, en lugar de conexiones directas por medio de cables físicos. Cuando este es caso, los puntos finales de una red virtual se transmiten a través de una red mayor. Al contrario de una aplicación común, formada por comunicaciones seguras en la red pública, una red VPN puede presentar o no funciones de seguridad, como la autenticación y el cifrado de contenidos.

Una VPN se puede utilizar con un token, tarjeta inteligente, etc., para proporcionar autenticación de dos factores.

Red Privada Virtual

Las redes privadas virtuales, también conocidas por sus siglas VPN (Virtual Private Network), son una clase de redes que se configuran dentro de una red pública. Para establecerlas, la integridad de los datos y la confidencialidad se protegen mediante la autentificación y el cifrado.

Red privada virtual

Mecanismo que permite el establecimiento de una comunicación segura y flexible entre dos nodos, entre un nodo y una red o entre dos redes cuando dicha comunicación ha de atravesar un medio inseguro. [CCN-STIC-401:2007]

Red Privada Virtual

Conexión segura entre dos extremos que utiliza como base una red insegura, normalmente Internet. [CCN-STIC-612:2006]

(en) VPN

Acronym for “virtual private network.” A computer network in which some of connections are virtual circuits within some larger network, such as the Internet, instead of direct connections by physical wires. The end points of the virtual network are said to be tunneled through the larger network when this is the case. While a common application consists of secure communications through the public Internet, a VPN may or may not have strong security features such as authentication or content encryption. A VPN may be used with a token, smart card, etc., to provide two-factor authentication.

Protected information system link utilizing tunneling, security controls (see Information Assurance), and endpoint address translation giving the impression of a dedicated line. [CNSSI_4009:2010]

(en) virtual private network (VPN)

(I) A restricted-use, logical (i.e., artificial or simulated) computer network that is constructed from the system resources of a relatively public, physical (i.e., real) network (e.g., the Internet), often by using encryption (located at hosts or gateways), and often by tunneling links of the virtual network across the real network. (See: tunnel.) [RFC4949:2007]

(en) virtual private network

Restricted-use logical computer network that is constructed from the system resources of a physical network,  e.g. by using encryption and/or by tunneling links of the virtual network across the real network. [ISO-18028-1:2006]

(en) Virtual Private Network - VPN

a private network utilising shared networks. E.g., A network based on a cryptographic tunnelling protocol operating over another network infrastructure. [ISO-18028-4:2005]

(en) Virtual Private Network

Virtual network built on top of existing networks that can provide a secure communications mechanism for data and IP information transmitted between networks. [NIST-SP800-77:2005]

(en) Virtual Private Networks (VPN)

A VPN is the application of encryption, data integrity,and authentication protocols to provide a secure connection between a D/A and a remote device or user. The authentication controls restrict the connection ability to only authorized users; the encryption controls ensure data confidentiality between the D/A and the remote device/user; the data integrity controls protect the data from modification during transit between the D/A and the remote user. When the data stream itself is also encrypted, the use of VPNs to send already-encrypted communications through an encrypted tunnel constitutes a form of double encryption.

(en) Virtual Private Network (VPN)

A restricted-use, logical (i.e., artificial or simulated) computer network that is constructed from the system resources of a relatively public, physical (i.e., real) network (such as the Internet), often by using encryption (located at hosts or gateways), and often by tunneling links of the virtual network across the real network. For example, if a corporation has LANs at several different sites, each connected to the Internet by a firewall, the corporation could create a VPN by (a) using encrypted tunnels to connect from firewall to firewall across the Internet and (b) not allowing any other traffic through the firewalls. A VPN is generally less expensive to build and operate than a dedicated real network, because the virtual network shares the cost of system resources with other users of the real network.

(fr) VPN

Acronyme de «virtual private network», réseau privé virtuel. Réseau informatique dans lequel certaines connexions sont des circuits virtuels au sein d’un réseau plus important, comme Internet, remplaçant les connexions directes par des câbles physiques. Les points terminaux du réseau virtuel sont alors tunnelisés à travers le réseau de plus grande dimension. Alors qu’une application commune consiste en plusieurs communications sécurisées par le réseau Internet public, un VPN peut comporter ou non des fonctionnalités de sécurité, comme l’authentification ou le cryptage de contenu. Un VPN peut être utilisé avec un token, une carte à puce, etc., pour assurer une authentification à deux facteurs.

(fr) VPN (Virtual Private Network)

Réseau d'ordinateurs constituant un sous-réseau privé permettant l'échange d'informations à travers des réseaux d'une autre topologie comme si les ordinateurs en communication étaient situés au sein d'un même réseau local. Ces liaisons correspondent à des chemins protégés empruntant les réseaux publics comme Internet. Généralement, les VPN sont chiffrés afin de garantir la confidentialité des informations échangées.

(fr) VPN - Virtual Private Network (Réseau Privé Virtuel)

Un VPN est un réseau de données qui utilise les moyens de télécommunications d'un réseau public en ajoutant des services de sécurité et des protocoles de tunneling.

Internet est en général utilisé pour établir un VPN pour des raisons de coûts.
