Can you describe some of the ways you would secure a Cisco computer network?

"There are several ways I can secure a Cisco computer network. It begins with user education and ensuring the users know the importance of keeping their passwords secure and updating them frequently. Next, I install strong authentication software which ensures that only authorized users have access to the network. I also use methodologies including antivirus programs, firewalls, and VPN technology. Together, all of these steps ensure that the network is safe and that the user information and company data will not be compromised."
