Cisco Security Architectures

A Cisco troubleshooting methodology. It includes coverage of: how to create, operate and use Cisco Access lists; how to secure a network when access occurs via a Cisco Router; and the TCP/IP Protocol and its use with Cisco routers. There are a number of security discussions too, and these include: public network and private network security threats and how to prevent them; how firewalls and proxy servers can be used as a first line of defence; how to configure Cisco Routers to accept only specific recognized incoming packets; using the Cisco PIX Firewall and the Centri firewall; and how to use the special security features built into Cisco routers.
