Cisco Network Security

You have a router or routers installed and you are the network manager. You understand how important the security is to the business yet you need a reference manual to help make sure you are taking the right steps to ensure maximum security. This book may be just what you need. Pike covers the security risks and threats showing you what weaknesses usually occur and how to avoid them. He also goes into detail about what the threats are and the protection you'll need. Pike shows how important the architecture is and what router services and protocols need to be implemented and setup in order to maintain a high level of security. The design of the firewall and the use of Cisco PIX firewall including the features and configuration is taken apart in the book. Finally there is excellent coverage of the all important access lists, encryption both symmetric and asymmetric, IPSec management and configuration and coverage of the VPN with PPTP L2TP and IPSec. Overall this is helping me make the network safer and more reliable.
