【 摘 要 】

Communication networks, both data and telephone, are subject to attack by malicious individuals. One goal of the owners of communication networks is to defend the networks from attackers. For several years, firewalls have been used on data networks to help provide protection from attackers. Until recently, there was no comparable system to use with a telephone network. Several vendors have recognized the need for systems to protect telephone networks and have developed products to improve the security for telephone networks. Sandia evaluated the capabilities of commercial telephone firewall products. Based on the evaluation of the telephone firewall products, Sandia installed the SecureLogix TeleWall system at both the New Mexico and California sites. Sandia is currently in the early stages of applying the capabilities of the SecureLogix telephone network firewall system to the environment at Sandia. Any site that has invested in computer network security protection through the implementation of firewall and intrusion detection systems should also implement appropriate telephone network protection through a telephone firewall system.
