As evidenced by previous discussions concerning the many host system break-ins occurring throughout the Internet, the need for highly trained, quality, full-time host system administrators is clearly shown. But, there is also indication that this need is not being met; many sites do not manage systems such that the systems are secure and protected from intruder attacks. Many system managers are part-time at best and do not upgrade systems with patches and bug fixes as available.
Firewall management expertise is a highly critical job role, as a firewall can only be as effective as its administration. If the firewall is not maintained properly, it may become insecure, and may permit break-ins while providing an illusion that the site is still secure. A site's security policy should clearly reflect the importance of strong firewall administration. Management should demonstrate its commitment to this importance in terms of full-time personnel, proper funding for procurement and maintenance and other necessary resources.
