Key Features:
1. Centralized Management: Firewall Manager enables administrators to create security policies from a single location and automatically enforce them across all accounts and resources within an AWS Organization.
2. Integration with AWS Security Services: It works seamlessly with AWS WAF (Web Application Firewall), AWS Shield Advanced, VPC Security Groups, AWS Network Firewall, and Amazon Route 53 Resolver DNS Firewall. This integration provides comprehensive protection against various threats.
3. Automatic Policy Enforcement: When new resources are created in your accounts, Firewall Manager automatically applies the appropriate security policies, ensuring consistent protection across your entire infrastructure.
4. Compliance Monitoring: The service continuously monitors your resources for policy violations and provides detailed compliance reports. This helps organizations maintain their security posture and meet regulatory requirements.
5. Cross-Account Protection: Organizations can protect resources across multiple AWS accounts from a single administrator account, simplifying security management at scale.
Use Cases:
- Protecting web applications with AWS WAF rules across multiple accounts
- Implementing DDoS protection using Shield Advanced policies
- Managing VPC Security Groups consistently across your organization
- Deploying network firewall policies to segment and protect VPC traffic
Benefits:
- Reduces administrative overhead by automating security policy deployment
- Ensures consistent security standards across all accounts
- Provides visibility into compliance status organization-wide
- Scales security management as your AWS environment grows
AWS Firewall Manager requires AWS Organizations with all features enabled and an AWS Config subscription in each member account. It is a prerequisite for the AWS Certified Cloud Practitioner exam to understand how this service contributes to maintaining security and compliance in AWS environments.
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 provides a single pane of glass for managing security policies across multiple AWS accounts and resources.
Why is AWS Firewall Manager Important?
Organizations with multiple AWS accounts face significant challenges in maintaining consistent security policies. AWS Firewall Manager addresses these challenges by:
• Centralized Management: Manage security rules for all accounts from one place • Automatic Enforcement: New accounts and resources automatically receive security policies • Compliance Assurance: Ensures all resources adhere to organization-wide security standards • Time Savings: Eliminates the need to configure security rules account by account • Visibility: Provides a comprehensive view of security posture across the organization
How AWS Firewall Manager Works
AWS Firewall Manager operates through these key components:
1. Prerequisites: • AWS Organizations must be enabled • AWS Config must be enabled in all accounts • A Firewall Manager administrator account must be designated
2. Security Policies: You create security policies that define the rules to be applied. Firewall Manager supports: • AWS WAF rules - for web application protection • AWS Shield Advanced - for DDoS protection • Security Groups - for VPC-level access control • AWS Network Firewall - for network traffic filtering • Route 53 Resolver DNS Firewall - for DNS query filtering
3. Policy Scope: Define which accounts, organizational units, and resource types the policy applies to
4. Automatic Remediation: Non-compliant resources can be automatically brought into compliance
Key Features to Remember
• Cross-Account Management: Works across all accounts in AWS Organizations • Automatic Application: Policies apply to new resources as they are created • Compliance Monitoring: Identifies non-compliant resources and can auto-remediate • Integration: Works with AWS WAF, Shield Advanced, Security Groups, Network Firewall, and DNS Firewall
Common Use Cases
• Enforcing WAF rules across all Application Load Balancers and CloudFront distributions • Ensuring all EC2 instances have baseline security group rules • Deploying Shield Advanced protection to critical resources • Implementing consistent network firewall policies across VPCs
Exam Tips: Answering Questions on AWS Firewall Manager
When you see these scenarios, think AWS Firewall Manager:
1. Multi-account security management - Any question about managing security rules across multiple AWS accounts points to Firewall Manager
3. Automatic security policy enforcement - When the scenario requires new resources to receive security configurations upon creation
4. AWS Organizations + Security - The combination of AWS Organizations with security policy management indicates Firewall Manager
5. Compliance across accounts - Ensuring security compliance across an entire organization
Key Differentiators:
• AWS WAF alone = Single account, single resource protection • AWS Firewall Manager = Multi-account, organization-wide WAF management • Security Groups alone = Individual instance or resource level • Firewall Manager with Security Groups = Organization-wide security group policies
Remember: Firewall Manager requires AWS Organizations and AWS Config to function. If a question mentions managing firewall rules across an organization with multiple accounts, AWS Firewall Manager is typically the correct answer.
