Network and Communications Security

Domain 6 will discuss how network communication occurs, as well as methods used to secure that communication.

Course description

Data that travels, either to an external party or to various internal systems, needs to be protected on the medium that it travels through. That’s where the importance of network and communications security comes into play. The security in your organization’s network is just as important as the devices that sit on that network.
