Securing and Controlling Cisco Routers

Securing and Controlling Cisco Routers demonstrates proven techniques for strengthening network security. The book begins with an introduction to Cisco technology and the TCP/IP protocol suite, and the subsequent chapters cover subjects such as routing, routing protocols, IP addressing, and Cisco Authentication, Authorization, and Accounting services (AAA). The text then addresses standard, extended, time-based, dynamic, and reflexive access lists, as well as context-based control and Cisco Encryption Technology. In order to practice the material taught, the reader can log on to a real router and perform the commands.
