Step 3. Modify the Network Firewall, firewall policies, and rule groups

After successfully deploying the stack, CodePipeline initiates the CodeBuild stages. Each stage validates and deploys the Network Firewall components. After the deployment stage completes, you can view the AWS Network Firewall and firewall policy in the AWS Network Firewall console.

To modify the default network firewall, firewall policy, and created rule groups, refer to Configuring resources for Network Firewall.
