Connect and Protect: Networks and Network Security

Overview

This course provides a brief introduction to network architecture, operations, intrusion tactics, and security hardening. Learners will also be introduced to common network protocols and how systems use the TCP/IP model to communicate within a network. Learners will gain an understanding of network level vulnerabilities and how to secure a network against those vulnerabilities. Network security topics will include firewalls, virtual private networks (VPNs), system hardening, and virtual private networks. By the end of this course, you will: - Describe the structure of different computer networks. - Illustrate how data is sent and received over a network. - Recognize common network protocols. - Identify common network security measures and protocols. - Explain how to secure a network against intrusion tactics. - Compare and contrast local networks to cloud computing. - Explain the different types of system hardening techniques.

Syllabus

Network architecture

This module provides learners with an understanding of network architecture and mechanisms to secure the network. The module also introduces network security and explains how it relates to ongoing security threats and vulnerabilities.

Network operations

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.

Secure against network intrusions

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.

Security hardening

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.
