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.

In the book, you will find the things you need to know to operate the Cisco
IOS efficiently, effectively, and economically — but chiefly securely. Completing
the Practice Sessions included with most chapters will provide you with a solid
base for embarking on the Cisco Certified Network Administrator (CCNA) accreditation
programs, if you desire to do so.

You will build on tasks in each lesson and progressively move to more complex
tasks. At the end of the book, you will have a firm grounding in Cisco routers.
Following is a look at how the remainder of the book is organized.
