AWS Firewall Manager addresses the complex challenge of maintaining consistent and comprehensive security across multiple accounts and resources in an AWS organization. This service allows for the central configuration and management of various security rules, including AWS WAF, AWS Shield Advanced, Amazon VPC security groups, network ACLs, AWS Network Firewalls, and Amazon Route 53 Resolver DNS Firewall rules.
The technical architecture of Firewall Manager is tightly integrated with AWS Organizations, enabling the enforcement of a common set of security policies across all accounts and resources. It requires prerequisites such as enabling AWS Organizations, setting up a Firewall Manager administrator account, and enabling AWS Config for each member account. Optionally, AWS Resource Access Manager can be enabled to facilitate the sharing of resources like AWS Network Firewalls and Route 53 Resolver DNS Firewall rules.
Operationally, Firewall Manager automates the application of security policies to new resources as they are added, ensuring compliance from the outset. It supports the grouping of resources based on tags or types, and allows for the subscription of all member accounts to AWS Shield Advanced protections. The service also integrates with Managed Rules for AWS WAF, providing pre-configured rules for easy deployment.
Key operational considerations include the need for careful policy configuration to avoid overly restrictive or permissive rules, and the monitoring of compliance status to ensure all resources adhere to the defined security policies. Additionally, costs are incurred based on the underlying services used, such as AWS WAF and AWS Config, which can add up especially in large-scale deployments.
From a technical standpoint, Firewall Manager supports real-time monitoring and automatic remediation of non-compliant resources. It also provides centralized monitoring of DDoS attacks across the organization, enhancing the overall security posture. However, it is crucial to manage quotas and limits associated with the service to avoid service disruptions.
