Appendix ECisco firewall commands

Currently, firewalls are the primary devices used to protect the outside perimeter of a corporate, military, or government network infrastructure. Properly configured, a firewall can be very useful in preventing malicious users on the public Internet from accessing private data, even when the organization has a connection to the Internet. Cisco is a major supplier of Internet infrastructure devices, such as routers, firewalls, and virtual private networks (VPNs). Because most networks encountered will have a firewall, and because Cisco is a major supplier of network infrastructure components, the commands used on a Cisco PIX firewall will be covered.
