AWS WAF provides cloud-native protection for applications hosted on AWS. This guide shows you how to integrate Fraudcache threat intelligence feeds with AWS WAF IP sets for automated protection.
AWS WAF Overview
AWS Web Application Firewall (WAF) protects web applications from common exploits. It integrates with CloudFront, Application Load Balancer, API Gateway, and AppSync.
IP sets in AWS WAF allow you to define collections of IP addresses that can be referenced in web ACL rules. By populating these IP sets with Fraudcache threat data, you block malicious traffic at the AWS edge.
Integration Steps
- Create an IP Set - In the AWS WAF console, create a new IP set. Choose the appropriate scope (CloudFront or Regional) based on your application architecture.
- Create a Web ACL Rule - Add a rule to your Web ACL that references the IP set. Set the action to Block for requests matching IPs in the set.
- Automate Updates - Use AWS Lambda with EventBridge (CloudWatch Events) to periodically fetch Fraudcache feeds and update the IP set via the AWS SDK.
Best Practices
Use Rate-Based Rules
Combine IP blocking with rate-based rules to catch new attackers before they appear in threat feeds.
Layer with Managed Rules
Use AWS Managed Rules alongside custom IP sets for defense in depth against common attack patterns.
Conclusion
AWS WAF integration with Fraudcache provides cloud-native protection that scales automatically with your AWS infrastructure. By automating IP set updates, you maintain current protection without manual intervention.
