Virtual Private Networks (VPNs) provide a way for remote workers and sales staff to communicate over an insecure public network. In this course, instructor Lisa Bock covers core strategies that you can use to secure a network with a VPN, and ensure data confidentiality, integrity, and authentication. Lisa goes over different types of VPN topologies, such as hair pin, split-tunnel, always-on, and NAT traversal, along with the various components and protocols. She explains how to work with the Cisco Adaptive Security Appliance (ASA), which offers functions to secure a network that include firewall features, malware defense, intrusion prevention, and content monitoring. She also dives into the IPsec framework, VPN configuration, setting up a remote access VPN, and preparing your site for an IPsec VPN. By the end of this course, you'll have the specialized knowledge needed to secure Cisco networks using VPN technology
