SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires boto3, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Protect API Gateway endpoints from common web attacks and abuse by configuring AWS WAF with managed rule groups, rate limiting, bot control, IP reputation filtering, and monitoring.

Core Features & Use Cases

  • Create and manage a Web ACL with AWS managed rule groups for OWASP Top 10 protection.
  • Configure rate-based rules to throttle abusive traffic and protect endpoints like /api/auth/login.
  • Enable Bot Control and IP reputation filtering to identify and block automated threats.
  • Implement custom rules (e.g., API key headers, geo-restrictions, max body size) to enforce API security policies.
  • Attach the Web ACL to API Gateway stages and enable comprehensive logging and monitoring via CloudWatch and Kinesis Firehose.

Quick Start

Configure your API Gateway with AWS WAF by creating a Web ACL, adding managed rule groups, and attaching the Web ACL to the API stage for live protection.

FAQPage Schema
How do I configure AWS WAF to protect API Gateway endpoints from OWASP Top 10 attacks?

You can configure AWS WAF for API Gateway by creating a Web ACL with managed rule groups for OWASP Top 10 protection, then attaching the ACL to your API stage to block common web attacks and abusive traffic.

What's the best way to set up rate limiting on an AWS API Gateway to stop abusive traffic?

The best way to set up rate limiting on AWS API Gateway is configuring rate-based rules within an AWS WAF Web ACL to throttle abusive traffic and protect specific endpoints like /api/auth/login from flooding.

Can I block bots and filter IP reputation for public REST APIs using AWS WAF?

Yes, you can block bots and filter IP reputation for public REST APIs by enabling Bot Control and IP reputation lists within an AWS WAF Web ACL to identify and block automated threats before they reach your endpoints.

Do I need specific IAM permissions to associate a Web ACL with API Gateway stages?

Yes, associating a Web ACL with API Gateway stages requires appropriate AWS IAM permissions for wafv2, CloudWatch, and Kinesis Firehose logging to manage rules and enable comprehensive traffic monitoring.

How do I add custom rules for API key headers and geo-restrictions to an AWS WAF Web ACL?

You add custom rules to an AWS WAF Web ACL by defining conditions for API key headers, geo-restrictions, and max body size to enforce API security policies and control access to your API Gateway endpoints.

How does logging and monitoring work when securing API Gateway with AWS WAF?

Logging and monitoring for AWS WAF on API Gateway works by sending traffic logs via Kinesis Firehose and CloudWatch, providing comprehensive visibility and alerting into blocked requests and rule matches across environments.
