Qualification of the firewall administrator
Two experienced people are generally recommended for the day-today administration of the firewall. In this manner, availability of the firewall administrative function is largely ensured. Security of a site is crucial to the day-to-day business activity of an organization. It is, therefore, required that the administrator of the firewall have a sound understanding of network concepts and implementation. For instance, because most firewalls are TCP/IP based, a thorough understanding of this protocol is mandatory. An individual who is assigned the task of firewall administration must have good hands-on experience with networking concepts, design, and implementation, so the firewall is configured correctly and administered properly. Firewall administrators should receive periodic training on the firewalls in use, as well as in network security principles and practices.
