Een goede firewall controleert alle toegang tot het intranet. Hij gebruikt daarvoor identificatiegegevens die met een datapakketje worden meegezonden. Op grond van die gegevens en een aantal vastgestelde regels neemt de firewall de beslissing of een pakket wel of niet door mag gaan naar het lokale netwerk. Een goede firewall laat dan ook geen enkel pakket door dat geen uitdrukkelijke toegang heeft. De belangrijkste taak van de firewall is het afschermen van data die niet bestemd is voor de open buitenwereld. |
