Summary

During the course of this chapter, you learned how to secure access to the console, AUX ports, and the VTY lines, how to set up secure remote access, and how to lock down administrative access on a Cisco device. Furthermore, you discovered how to establish a secure tunnel between two remote sites, such as Cisco IOS routers, to simply extend the LAN at the HQ corporate office to a remote branch site using a VPN.

I hope this chapter has been informative for you and is helpful in your journey toward learning how to implement and administer Cisco solutions and prepare for the CCNA 200-301 certification. In the next chapter, Implementing Access Controls Lists (ACLs), you will learn how to create and implement Layer 3 security controls on a Cisco IOS router to filter traffic.
