Chapter Description

Several different parts of a network need to be secured from internal and external attack. This chapter addresses the routed data plane, including the Cisco IOS Software features that can be used to secure the network user data that traverses the network, and discusses how to configure these features on the network devices within the network.

This chapter covers the following subjects:

  • Routed data plane attack types: Reviews the types of attack that are focused on the routed data plane.
  • Access control lists (ACL): Covers the fundamentals of using ACLs and the configuration and verification commands to use.
  • Flexible Packet Matching (FPM): Covers the steps involved in developing a traffic class and policy and assigning it to an interface. It also goes over the verification commands that can be used in configuration and troubleshooting.
  • Flexible NetFlow: Reviews the fundamentals of Flexible NetFlow and describes the configuration and verification commands to use it.
  • Unicast Reverse Path Forwarding (Unicast RPF): Covers the basics of how Unicast RPF functions and discusses the commands required to configure and verify it.

Several different parts of a network need to be secured from internal and external attack. The three planes as defined by Cisco include the data plane, management plane, and control plane, and these are split between those focused on the switched parts of the network and those focused on the routed parts of the network. This chapter addresses the routed data plane, including the Cisco IOS Software features that can be used to secure the network user data that traverses the network and discusses how to configure these features on the network devices within the network.

"Do I Know This Already?" Quiz

The "Do I Know This Already?" quiz helps you decide whether you really need to read the entire chapter. If you already intend to read the entire chapter, you do not necessarily need to answer these questions now.

The ten-question quiz, derived from the major sections in the "Foundation Topics" section of this chapter, helps you determine how to spend your limited study time.

Table 8-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

CAUTION

The goal of self-assessment is to gauge your mastery of the topics in this chapter. If you do not know the answer to a question or are only partially sure of the answer, you should mark this question wrong for purposes of the self-assessment. Giving yourself credit for an answer that you correctly guess skews your self-assessment results and might provide you with a false sense of security.
