AWS Web Application Firewall
AWS Firewall Manager
SAA-C02- Exam Prep
The course is part of this learning path
This course looks at the key Security services within AWS relevant to the Solution Architect associate exam. Core to security is Identity & Access Management, commonly referred to as IAM. This service manages identities and their permissions that are able to access your AWS resources and so understanding how this service works and what you can do with it will help you to maintain a secure AWS environment. IAM is an important service in ensuring your resources are secure.

Hello and welcome to this lecture where I shall introduce the components of the AWS Firewall Manager service. There are primarily three different components to Firewall Manager that allow you to control and manage walls across multiple AWS accounts within your AWS organization. These being, WAF rules, rule groups and Firewall Manager policies. I covered what AWS WAF rules are in a previous lecture so I won't go over the same information again. So next we have rule groups. These simply allow you to group together one or more WAF rules that will all have the same action applied when the conditions are met within a rule. You have two options for your rule groups, you can create your own and add your own WAF rules or you can purchase existing rule groups pre-configured with set AWF WAF rules by the AWF Marketplace. By using the Marketplace rule groups it provides a number of benefits. For example they are all pre-configured and ready to deploy and are supplied by AWS and other AWS approved partner companies. Many of them allow protections against known vulnerabilities, specifically those highlighted within the open web application security project, the OWASP top 10 list, and they could help you to gain compliance to specific regulations such as PCI or HIPAA. Unlike web rules, rule groups can only contain one of two actions.
These being either block or count. And they have the same meaning as defined within the WAF section. There is no allow action for rule groups. Also you can only have 10 rules per rule group which can't be increased. For other limitations of Firewall Manager please see the following link. Once you have created your rule groups containing your rules, you then have to create an AWS Firewall Manager Policy. This policy simply contains the rule groups that you want to assign to your AWS resources. It's important to point out that you can only have two rule groups per policy, one customer created rule group, and one AWS Marketplace rule group. This limit cannot be changed. So to recap, AWS WAF rules are created or selected first, which as we know contain conditions. WAF rules can then be added to a rule group which will have either a block or a count action associated. Finally, a rule group is then added to an AWS Firewall Manager Policy which is then associated to AWS resources, such as your cloud front distributions or application load balances. Do be aware that the cost of each policy is $100 per policy, per region, per month. That has brought me to the end of this short lecture. Coming up next I will provide a demonstration on how to use and create some of these components to add to our policy.
