This Defending the Perimeter from Cyber Attacks course will teach you to ensure the confidentiality, integrity, and availability of your organization’s information by protecting your communications and data. You will learn how to define and implement security principles, install and customize secure firewalls, build Virtual Private Network (VPN) tunnels, and safeguard your organization’s network perimeter against malicious attacks.
