This portion of the Deployment guide will guide you on how to add Infoblox TIDE feeds to your AWS Route 53 DNS Firewall domain list. Please note that by utilizing an AWS Route 53 firewall, charges will be incurred from AWS. Infoblox does not charge extra for the use of TIDE, however a BloxOne Threat Defense Advanced license is required for this feature. 

## **Prerequisites**

he following are prerequisites to add TIDE feeds to AWS’ DNS Firewall domain list:

- BloxOne:
  - BloxOne Threat Defense Advanced subscription
  - A CSP user account with BloxOne Threat Defense administrator permissions
- AWS:
  - A Preconfigured VPC

## **Known Limitations**

By default, AWS Route53 DNS Firewall allows adding up to 100,000 domains per list. If you need to publish more entries, please contact AWS. Please note that by default the script used in this guide will overwrite any existing Domains in the AWS Route 53 DNS Firewall domain list with Replace via the import_firewall_domains function. Additionally, note that the AWS Route 53 DNS Firewall domain list only accepts domain names, one line at a time. For more information on AWS Route Firewall domain lists, please see the AWS documentation <u>[here](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver-dns-firewall-user-managed-domain-lists.html)</u>.

## **Workflow**

1. Acquire a TIDE API Key.
2. Create an AWS Route 53 DNS Firewall domain list or use an existing one.
3. Create a rule group or use an existing one.
  1. Assign the AWS Route 53 DNS Firewall domain list to the rule group.
  2. Create a rule and associate that rule with your VPC.
4. Create an S3 Bucket.
  1. Create a simple text file in the S3 bucket.
  2. Save the S3 Bucket name and file name for use in the Lambda function’s environment variables.
5. Acquire parameters for a Lambda function.
  1. Acquire a TIDE API Call URL.
  2. Acquire an AWS Route 53 DNS Firewall domain list ID.
6. Create a Lambda function.
  1. Input environment variables.
7. Create IAM Policies.
8. Test the Lambda function.
9. Create an AWS EventBridge Schedule.
