Connect and Protect: Networks and Network Security

This module explores the network tools, protocols, and techniques that govern the functioning of network systems. Communication takes place on a network and that communication can introduce vulnerabilities to the network. Learners will understand protocols that regulate network communication and be introduced to the tools and concepts that play a major role in ensuring network operations are safe and reliable.

In this section of the course, learners will explore different types of network attacks and various tactics used to secure compromised network systems and devices. Malicious actors employ a variety of methods to exploit vulnerabilities in network infrastructure and this requires security professionals to always stay aware of potential loopholes. Being aware of all the ways that networks are targeted is an important skill for a cybersecurity analyst.

In this section of the course, learners will familiarize themselves with network hardening practices that strengthen network systems over time. Security professionals work against experiencing numerous security breaches, which is why it is important to take preliminary security measures to remain one step ahead of attackers. Malicious actors are constantly evolving in their intrusion methods and network security hardening is a defensive strategy that aims to prevent or lessen the chances of future attacks taking place. Security hardening also involves securing applications over cloud systems and addressing the unique security challenges posed by cloud infrastructures.
