- [Lisa] Thank you for watching. In this course I began with an overview of secure routing and switching. I reviewed the control, data and management plane, along with router and switch security basics. I covered layer three attacks and discussed how to secure Cisco routers. I discussed configuring privilege levels, role-based command line interface access, and routing update authentication. Then I reviewed layer two attacks such as a Macof attack, VLAN hopping, and DHCP spoofing, and then discussed how to secure Cisco switches. I covered mitigation procedures such as dynamic ARP inspection and BPDU guard, and then wrapped up with a discussion on VLAN security and looked at the security implications of a private VLAN and a native VLAN.
