The purpose of a firewall is to protect a computer or a network against malicious access. In a perfect world every daemon or service, on every machine, is perfectly configured and immune to security flaws, and all users are trusted implicitly to use the equipment as intended. However, this is rarely, if ever, the case. Daemons may be misconfigured, or updates may not have been applied for known exploits against essential services. Additionally, you may wish to choose which services are accessible by certain machines or users, or you may wish to limit which machines or applications are allowed external access. Alternatively, you simply may not trust some of your applications or users. For these reasons, a carefully designed firewall should be an essential part of system security.

Le but d'un pare-feu est de protéger un ordinateur ou un réseau contre des accès non autorisés. Dans un monde parfait chaque démon ou service, sur chaque machine, est parfaitement configuré et insensible aux problèmes de sécurités et on peut faire confiance à tous les utilisateurs pour utiliser l'équipement comme cela était prévu. Cependant, c'est rarement, voire jamais le cas. Les démons peuvent être mal configurés, ou les mises à jour peuvent ne pas être appliquées malgré des failles connues contre des services critiques. En plus, vous pourriez vouloir choisir quels services sont accessibles à quels utilisateurs ou machines, ou limiter l'accès au réseau à des machines ou des applications. Autrement, vous pouvez simplement ne pas faire confiance à vos utilisateurs ni à vos applications. Pour ces raisons, un pare-feu correctement conçu devrait être un composant essentiel de tout système de sécurité.

O propósito de um firewall é o de proteger um computador ou uma rede de comunicação contra acesso malicioso. Em um mundo perfeito, cada processo de segundo plano ou serviço, em cada máquina, está perfeitamente configurado e imune a falhas de segurança e todos(as) os(as) usuários(as) são implicitamente confiáveis para usar o equipamento conforme pretendido. Entretanto, isso é raramente, se é que existe, o caso. Processos de segundo plano possivelmente estejam mal configurados ou atualizações possivelmente não tenham sido aplicadas para maus usos em benefício próprio conhecidos contra serviços essenciais. Adicionalmente, você possivelmente deseje escolher quais serviços são acessíveis por certas máquinas ou por usuários(as); ou você possivelmente deseje limitar para quais máquinas ou aplicativos são permitidas o acesso externo. Alternativamente, você possivelmente simplesmente não confie em alguns dos seus aplicativos ou usuários(as). Por essas razões, um firewall cuidadosamente projetado deveria ser uma parte essencial da segurança do sistema.

While a firewall can greatly limit the scope of the above issues, do not assume that having a firewall makes careful configuration redundant, or that any negligent misconfiguration is harmless. A firewall does not prevent the exploitation of any service you offer outside of it. Despite having a firewall, you need to keep applications and daemons properly configured and up to date.

This is a system placed between the Internet and an intranet. To minimize the risk of compromising the firewall itself, it should generally have only one role&mdash;that of protecting the intranet. Although not completely risk-free, the tasks of doing the routing and IP masquerading (rewriting IP headers of the packets it routes from clients with private IP addresses onto the Internet so that they seem to come from the firewall itself) are commonly considered relatively secure.

This type of firewall performs masquerading or routing, but grants public access to some branch of your network that is physically separated from your regular intranet and is essentially a separate network with direct Internet access. The servers on this network are those which must be easily accessible from both the Internet and intranet. The firewall protects both networks. This type of firewall has a minimum of three network interfaces.
