Abstract

The invention concerns a device for securely browsing or using message services on external communication networks, such as Internet. It consists of a box containing a system for dialogue on said external networks and a communication system with work console completely isolating the internal network of the enterprise, the organisation or the structure from said insecure external structures. The device is particularly designed for structures wishing to provide fail-safe protection for their computer system and their private networks against intrusions and abuses possibly caused by external communication networks.

Description

Dispositif de protection des systèmes informatiques contre les intrusions ou malveillances issues des réseaux de communication ouvert sur l'extérieur. Device for protecting computer systems against intrusions or malicious acts from communication networks open to the outside.
La présente invention concerne un dispositif pour protéger les systèmes informatiques contre les intrusions ou malveillances issues d'un réseau de communication ouvert sur l'extérieur tel que celui nommé communément "internet".The present invention relates to a device for protecting computer systems against intrusions or malicious acts originating from a communication network open to the outside such as that commonly called "internet".
La protection traditionnellement utilisée est constituée d'un logiciel habituellement appelé "fire wall". Ce type de protection n'est pas infaillible car il ne résout pas le problème de la présence physique du réseau de communication externe sur le ou les serveur (s) de données ou de messagerie .The protection traditionally used consists of software usually called "fire wall". This type of protection is not foolproof because it does not solve the problem of the physical presence of the external communication network on the data server or servers.
Le dispositif selon l'invention permet de remédier à cet inconvénient. Il comporte en effet un boîtier comprenant :The device according to the invention overcomes this drawback. It indeed comprises a box comprising:
- un système d'exploitation sur technologie carte électronique à processeur avec utilitaire de configuration et de connexion au réseau extérieur de communication.- an operating system on processor electronic card technology with configuration utility and connection to the external communication network.
- la connexion au réseau extérieur de communication est réalisée par l'intermédiaire d'une interface "ethernet" au travers d'un réseau local avec un serveur spécialisé ou par l'intermédiaire d'un communicateur de type modem, RNIS, ADSL ou autre à titre d'exemple non limitatif.- the connection to the external communication network is made via an "ethernet" interface through a local network with a specialized server or via a modem, ISDN, ADSL or other type of communicator by way of nonlimiting example.
- un système de commutation et adaptation rapide permet de "basculer" une console ou un poste de travail du réseau local et/ou externe de l'entreprise, de l'organisme ou de la structure sur le réseau extérieur de communication dit "internet" ou autre par l'intermédiaire du système d'exploitation défini ci-dessus.- a switching and rapid adaptation system makes it possible to "switch" a console or a workstation on the local and / or external network of the company, organization or structure on the external "internet" communication network or other through the operating system defined above.
Le principe consiste à ne réaliser les connexions au réseau de communication externe (internet ou autre à titre non limitatif) uniquement sur un système connexe constitué par le système d'exploitation défini ci-dessus. Le réseau de l'entreprise, de l'organisme ou de la structure est alors complètement indépendant physiquement du réseau de communication externe (internet ou autre) ou de toute connexion vers un quelconque système de communication externe (internet ou autre. Ainsi, aucun signal et/ou aucune donnée extérieurs ne peuvent être mis en contact avec les bus adresses et données des systèmes internes (locaux ou distants) de l'entreprise, de l'organisme ou de la structure.The principle consists in making connections to the external communication network (internet or other without limitation) only on a related system constituted by the operating system defined above. The network of the company, the organization or the structure is then completely physically independent of the external communication network (internet or other) or of any connection to any external communication system (internet or other. Thus, no signal and / or no external data can be brought into contact with the address and data buses of the internal systems (local or remote) of the company, organization or structure.
L'unité centrale raccordée au réseau de l'entreprise, de l'organisme ou de la structure est raccordée au présent dispositif et le clavier, la souris et l'interface d'affichage sont gérés et commutés par le système de commutation décrit ci- dessus faisant partie du présent dispositif.The central unit connected to the network of the company, organization or structure is connected to this device and the keyboard, mouse and display interface are managed and switched by the switching system described above. above forming part of this device.
Aucune connexion physique entre le réseau de communication externe ("internet" ou autre) et l'unité centrale du poste de travail n'est possible. La liaison avec le réseau externe de communication ("internet" ou autre) est réalisée par le dispositif, soit par modem soit par un autre réseau local indépendant passant par un serveur spécialisé indépendant qui n'a pas de liaison physique avec le réseau de l'entreprise, de l'organisme ou de la structure.No physical connection between the external communication network ("internet" or other) and the central unit of the workstation is possible. The connection with the external communication network ("internet" or other) is carried out by the device, either by modem or by another independent local network passing through an independent specialized server which has no physical connection with the network of the company, organization or structure.
Dans la forme de réalisation, le système est composé :In the embodiment, the system is composed:
- d'une carte électronique à et avec processeur (dite "carte mère") , - d'une mémoire Ram de travail,- an electronic card with and with processor (called "motherboard"), - a working Ram memory,
