Chapter 6. Securing the Management Plane on Cisco IOS Devices

Accessing and configuring Cisco devices is a common occurrence for an administrator. Malicious router management traffic from an unauthorized source can pose a security threat. For example, an attacker could compromise router security by intercepting login credentials (such as the username and password). This chapter introduces the concept of the management plane (which is a collection of protocols and access methods we use to configure, manage, and maintain a network device) and examines how to protect it.
