This chapter showed you a lot of basic tasks that you will perform to secure access to your router, including local (console and auxiliary) and remote (Telnet, SSH, web browser, and SNMP) access. Some of these access methods are more secure than others; carefully evaluate which method you want to use, and secure it appropriately. As an added measure of security, you can assign command levels and create accounts that correspond to those levels, restricting what an administrator can do on your router.

Next up is Chapter 4, "Disabling Unnecessary Services," which shows you how disable applications and protocols that typically are not necessary on a firewall-hardened router, including those that present security risks.
