内容説明 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. 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. At the end of most chapters， readers will find the unique opportunity to practice what they have learned. Readers will be able to log on to a real router， practice commands， and gather information as shown in the chapter. To further round out this understanding of routers， Securing and Controlling Cisco Routers reviews Trojan Ports and Services and provides additional resources such as Web sites， mailing lists， bibliographies， glossaries， acronyms， and abbreviations.
