Welcome, to domain four, Network Security for the Certified and Cybersecurity
certification. Networks are the pipelines that allow us to communicate in
ways that were unheard of only a few decades ago.
We can share data with friends and business partners around
the world in seconds. In this module, which accounts for 24% of the exam content,
we'll examine the types of networks we use and explore how
to secure those networks so that they provide reliable and
accurate transmission of data.
This course is divided into three modules, Computer Networking,
Network Threats and Attacks, and Network Infrastructure.
This will provide us with a glimpse into the design, architecture, and
function of networks, and open our eyes to the ways we can protect those
networks and the systems that rely on those networks.
Let's get started with the first module, Computer Networking.
