Lab description

Google Cloud Armor provides application-level protection from common front-end threats such as distributed denial-of-service (DDoS) attacks, cross-site scripting, and SQL injections. Google Cloud Armor security policies are applied on HTTP(S) load balancers at the Google Cloud edge, which means it's evaluating potential threats, closer to the traffic source. 

Google VPC Firewall Rules are applied at the network layer of your application and are meant to protect your VM instances within a specific network. 

Both of these safeguards apply rules that either allow or deny incoming traffic. A key difference between the two is the level at which they evaluate the traffic. 

In this lab, you will configure a Google VPC Firewall Rule and a Google Cloud Armor security policy. Both security measures will be configured to protect an application made up of a Google Compute Engine Instance Group that is served traffic from an HTTP(S) Load Balancer.

Learning Objectives

Upon completion of this lab you will be able to:

  • Identify key differences between Google Cloud Armor and Google Firewall Rules
  • Secure your applications by allowing only Trusted IPs/Ranges with Firewall Rules
  • Protect your applications from common threats like DDoS with Google Cloud Armor

Intended Audience

This lab is intended for:

  • Software Developers
  • Network Engineers
  • Security Engineers

Prerequisites

Familiarity with the following will be beneficial but is not required:

  • A basic understanding of Google Cloud Platform Networking
