💡 Definition

AWS Firewall Manager is a security management service that allows you to centrally configure and manage firewall rules across your accounts and applications in AWS Organizations. It simplifies the management and deployment of WAF rules, AWS Shield Advanced protections, AWS Network Firewall rules, and VPC security groups across your entire organization.

🔑 Key Concepts

Centralized Management: Apply and manage security policies (firewall rules) from a single administrator account across all accounts in your AWS Organizations.
Organizational Scope: Easily deploy consistent security configurations across hundreds or thousands of accounts.
Automated Deployment: Automatically apply new rules or update existing policies to newly created accounts and resources.
Policy Types: Supports policies for WAF, AWS Network Firewall, AWS Shield Advanced, and Security Groups.
Compliance: Helps ensure all resources adhere to predefined security policies, aiding in compliance efforts.

⚙️ How it Works

From a central administrator account in AWS Organizations, you define security policies (e.g., "all web applications must have a WAF ACL attached"). Firewall Manager then automatically applies and enforces these policies across all specified accounts and resources in your organization. If a resource is created that doesn't comply, Firewall Manager can automatically remediate it or flag it as non-compliant.

🎯 Use Cases

Enterprise Security Operations: Standardizing security protections across large, multi-account AWS environments.
Compliance Enforcement: Ensuring consistent application of security rules to meet regulatory requirements.
Rapid Deployment of Protections: Quickly deploying new security measures across the entire organization.

💰 Pricing Model

Managed Rules: Charged based on the number of rules managed by Firewall Manager across your organization.
Firewall Deployments: Additional costs may apply for deploying underlying services like WAF or AWS Network Firewall.
