AWS Firewall Manager: Overview and Configuration Example

AWS Firewall Manager is a security management service that makes it easier to deploy and manage web application firewall (WAF) rules across your AWS organization. It enables you to centrally configure and manage WAF rules for your applications, ensuring consistent security policies across multiple accounts and resources. Here's a detailed overview of AWS Firewall Manager along with a configuration example:

Features of AWS Firewall Manager:

1. Centralized WAF Rule Management:

   • Provides centralized management of WAF rules across multiple AWS accounts and resources.
2. Global and Regional Rules:
   • Allows you to create global rules that apply to all resources or regional rules that apply to specific regions.
3. Managed Rule Groups:
   • Supports the use of managed rule groups to simplify rule management and stay up-to-date with the latest threat intelligence.
4. Policy Enforcement:
   • Enforces security policies consistently across applications and resources.
5. Integration with AWS Organizations:
   • Integrates with AWS Organizations for centralized management of WAF rules across linked accounts.
