Firewall Manager is a part of AWS Shield Advanced and provides a central place to manage your AWS WAF rules across multiple accounts and resources. It is particularly useful for organizations that require a consistent security posture across various applications and services.
To start using AWS Firewall Manager, you need to set it as part of your AWS Organizations master account and designate it as your AWS Firewall Manager administrator account.
As your security requirements evolve, you may need to modify your firewall policies. With AWS Firewall Manager, you can easily:
AWS Firewall Manager also provides compliance auditing. It assesses if your resources are in compliance with the policy rules and provides a detailed report. You can use AWS Security Hub to consolidate these reports and take action when resources become non-compliant.
Resource | Compliance Status |
---|---|
App-Load-Balancer-1 | Compliant |
Dev-API-Gateway | Non-Compliant |
Prod-S3-Bucket | Compliant |
AWS Config is also a valuable tool that works alongside Firewall Manager. It continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations.
In summary, managing network configurations in an ever-changing environment can be streamlined by using AWS Firewall Manager. The central management, ease of updating policies, and compliance reporting are invaluable for maintaining a robust security posture as requirements change.
By understanding these tools and regularly reviewing and adapting policies, you can ensure that your network configurations meet the current and future demands of your AWS environment, aiding you in your preparation for the AWS Certified Security – Specialty (SCS-C02) exam.

Correct Answer: A) True
Explanation: AWS Firewall Manager can be used to automatically apply AWS Shield Advanced across multiple accounts for DDoS protection.
Correct Answer: D) Automatic patching of the operating system
Explanation: AWS Firewall Manager does not deal with patching operating systems; it is focused on managing and applying AWS WAF rules, AWS Shield protections, and VPC security group rules.
Correct Answer: B) False
Explanation: AWS Firewall Manager allows central security administrators to enforce firewall rules, and these rules cannot be overridden by individual application owners without proper change procedures.
Correct Answer: A) EC2 instances and C) RDS instances
Explanation: AWS Firewall Manager supports the management of security groups for resources such as EC2 instances and RDS database instances.
Correct Answer: A) True
Explanation: AWS Firewall Manager has the ability to automatically apply rules to new resources created within the scope of the security policy.
Correct Answer: B) Resource groups
Explanation: In AWS Firewall Manager, resource groups are used to define the scope of the security policy, which can identify resources to include based on specific tags.
Correct Answer: B) False
Explanation: While AWS Firewall Manager is designed to manage AWS native services like AWS WAF, Shield Advanced, and VPC security groups, it can also work with AWS Marketplace third-party firewall solutions as part of the AWS Network Firewall.
Correct Answer: B) False
Explanation: Any changes made to individual AWS WAF rules can be overridden by AWS Firewall Manager policy updates if those rules fall within the scope of a managed policy.
Correct Answer: A) AWS Config
Explanation: AWS Firewall Manager relies on AWS Config to assess and audit the configuration of resources, including VPC security groups, to ensure they comply with the centralized policies.
AWS Firewall Manager is a security management service which allows customers to centrally configure and manage firewall rules across their accounts and applications in AWS Organizations. It simplifies the administration of network security rules, ensuring consistent policies are applied across all resources. With Firewall Manager, users can roll out AWS WAF rules, AWS Shield Advanced protections, and Amazon VPC security groups across multiple AWS accounts. It streamlines managing and monitoring firewall rules, ensuring compliance with the organization’s security policies.
Using AWS Firewall Manager, you can manage AWS WAF rules, which include web ACLs for filtering HTTP/HTTPS traffic, Shield Advanced protections for DDoS mitigation, and Amazon VPC security group rules that control traffic at the instance level. Additionally, Firewall Manager supports managing network firewall policies, offering stateful, managed, network firewall policies in your VPCs.
AWS Firewall Manager integrates with AWS Organizations to apply firewall rules across the accounts within the organization. The prerequisites for using Firewall Manager include having an AWS Organizations set up with all features enabled, and you must be using the organization’s master account. Additionally, you must have the appropriate AWS Config recording on in every region where you want the Firewall Manager to operate.
AWS Firewall Manager automates the process of setting up and applying security group rules across multiple VPCs or AWS accounts within an AWS Organization. When there are changes in requirements, Firewall Manager can quickly propagate updates to all applicable VPCs and accounts, ensuring consistency and compliance. It can also audit and remediate configurations that do not comply with the set policy.
AWS Firewall Manager supports compliance efforts by consistently applying firewall rules across an organization’s AWS environment. By defining a set of security policies and applying them centrally, it ensures that all resources are in compliance with regulatory requirements. It automatically audits the environment and provides details on non-compliant resources, which helps in remediation and maintaining compliance.
AWS Firewall Manager is particularly useful in scenarios where an organization’s network environment is dynamic, such as rapidly scaling cloud-based applications or frequent deployment of new services. For instance, when launching a new application across several regions and accounts that require consistent firewall configurations, Firewall Manager can rapidly deploy the necessary rules and manage them centrally, adapting to the new requirements without manual intervention in each account.
AWS Firewall Manager provides monitoring capabilities by integrating with AWS Config and Amazon CloudWatch. It reports on rule compliance and non-compliance across accounts and provides real-time alerts on security group changes and potential security incidents. Automated reporting helps identify risks, and audit logs can be used for forensic investigation or compliance auditing.
With AWS Firewall Manager, you can define Security Policies that automatically enforce rules and actions in response to certain triggers or identified threats. For example, if a new type of attack is discovered, you can quickly push updated AWS WAF rules across the organization to mitigate that threat. You can also integrate with AWS Lambda and Amazon CloudWatch for more complex automated responses based on specific criteria or logs.
AWS Firewall Manager simplifies administration by providing a central console from which to manage security policies and rules, rather than having to configure them individually across accounts or services. This centralization saves time and reduces potential errors, making it easier to enforce consistent security postures across an organization’s entire cloud infrastructure.
AWS Firewall Manager allows organizations to use AWS Marketplace rule groups created by third-party vendors. These rule groups can be incorporated into the organization’s firewall policies and distributed across accounts just like AWS-managed rule groups. This integration supports the management of a comprehensive set of firewall rules, both AWS-managed and third-party, from one place.
AWS Firewall Manager integrates seamlessly with several AWS services, including AWS WAF for web traffic filtering, AWS Shield for DDoS protection, AWS Config for compliance tracking, Amazon CloudWatch for logging and monitoring, Amazon VPC for network isolation and segmentation, and AWS Organizations for centralized management across accounts. These integrations enable a holistic approach to network security and management.
Yes, AWS Firewall Manager allows for rapid updates to firewall policies, which can include emergency “block” or “allow” overrides. In the event of an attack or breach, you would update the relevant firewall policy with a new rule to mitigate the threat. This update is quickly propagated to all accounts and resources governed by that policy. The automated nature of Firewall Manager ensures that such critical updates are implemented consistently and without delay across the organization’s AWS footprint.
