Students will learn to work with various protocols, and create security in router-based networks and across different platforms. They will also use some of the techniques that network attackers commonly use to learn how to best stop them.

We designed the Network Security Fundamentals course for the student who is a Network Administrator responsible for maintaining a wide range of network technologies.

Network Security Fundamentals is designed to provide Network Administrators with an awareness of security-related issues and the essential skills they need to implement security in a given network. This course is the first course offered in Level One: Defense of the Security Certified Program.
