Introduction to Course 3 + course 3 overview

Introduction


You've learned about security domains in previous courses.
Now we'll explore one of those domains further: networks.
It's important to secure networks because network-based attacks are growing in both
frequency and complexity.


Hi there! My name is Chris, and I'm the Chief Information Security Officer for
Google Fiber.
I'm excited to be your instructor for this course!
I've been working in network security and engineering for over 20 years, and
I'm looking forward to sharing some of my knowledge and experience with you.


This course will help you understand the basic structure of a network (also
referred to as network architecture) and commonly used network tools.
You'll also learn about network operations and explore some basic network protocols.
Next, you'll learn about common network attacks and
how network intrusion tactics can prevent a threat to a network.
Finally, the course will provide an overview of security hardening practices
and how you might use them to help secure a network.


There's a lot to learn in securing networks, and
I'm excited to go on this journey with you.
Ready to get started?
Let's go!

Course 3 overview

Course 3 welcome banner

Hello and welcome to Connect and Protect: Networks and Network Security, the third course in the Google Cybersecurity Certificate. You’re on an exciting journey!

By the end of this course, you will develop a greater understanding of network architecture, operations, intrusion tactics, common types of network vulnerabilities and attacks, and how to secure networks. You’ll also be introduced to common network protocols, firewalls, virtual private networks (VPNs), and system hardening practices. 

Certificate program progress

The Google Cybersecurity Certificate program has eight courses. Connect and Protect: Networks and Network Security is the third course.

  1. — Learn about incident classification, escalation, and ways to communicate with stakeholders. This course closes out the program with tips on how to engage with the cybersecurity community and prepare for your job search.

Course 3 content

Each course of this certificate program is broken into weeks. You can complete courses at your own pace, but the weekly breakdowns are designed to help you finish the entire Google Cybersecurity Certificate in about six months.

What’s to come? Here’s a quick overview of the skills you’ll learn in each week of this course.

Week 1: Network architecture

Five icons show the course followed by the four weeks sequentially from left to right with week 1 highlighted.

You'll be introduced to network security and explain how it relates to ongoing security threats and vulnerabilities. You will learn about network architecture and mechanisms to secure a network.

Week 2: Network operations 

Five icons show the course followed by the four weeks sequentially from left to right with week 2 highlighted.

You will explore network protocols and how network communication can introduce vulnerabilities. In addition, you'll learn about common security measures, like firewalls, that help network operations remain safe and reliable.

Week 3: Secure against network intrusions

Five icons show the course followed by the four weeks sequentially from left to right with week 3 highlighted.

You will understand types of network attacks and techniques used to secure compromised network systems and devices. You'll explore the many ways that malicious actors exploit vulnerabilities in network infrastructure and how cybersecurity professionals identify and close potential loopholes.

Week 4: Security hardening

Five icons show the course followed by the four weeks sequentially from left to right with week 4 highlighted.

You will become familiar with network hardening practices that strengthen network systems. You'll learn how security hardening helps defend against malicious actors and intrusion methods. You'll also learn how to use security hardening to address the unique security challenges posed by cloud infrastructures.

What to expect

Each course offers many types of learning opportunities:
