AWS Firewall Manager is a security management service offered by AWS that allows you to centrally configure and manage firewall rules across your AWS environment. It’s primarily used to manage and enforce security policies across multiple accounts, regions, and VPCs (Virtual Private Clouds) within an AWS Organization.
Key Features:
Centralized Firewall Management: You can create and manage security policies from a single, centralized location, reducing the complexity of firewall configurations across multiple accounts and regions.
Automated Policy Enforcement: Firewall Manager automatically applies your security policies to new and existing resources. This ensures that your network security is consistently enforced.
Integration with AWS Services:
AWS WAF (Web Application Firewall): Firewall Manager integrates with AWS WAF to protect your web applications from common web exploits.
AWS Shield Advanced: For DDoS protection, Firewall Manager integrates with AWS Shield Advanced to mitigate attacks and enforce DDoS protection across accounts.
VPC Security Groups: You can manage security groups across multiple accounts to ensure consistency in your firewall rules.
AWS Network Firewall: You can manage stateful firewalls for traffic filtering across VPCs.
Policy Creation and Deployment: You can define policies for resources, such as WAF rules, security group policies, and network firewall policies, and automatically apply them across your organization.
Compliance: It helps organizations stay compliant with security best practices and industry standards by enforcing uniform policies across all accounts.
Multi-Account Support: As part of AWS Organizations, Firewall Manager works across multiple AWS accounts, simplifying cross-account security management.
Visibility and Reporting: AWS Firewall Manager provides dashboards and reports to help track the compliance and enforcement of your security policies.
Use Cases:
- Enforcing consistent security policies across all applications and resources in an organization.
- Simplifying DDoS mitigation by automatically applying AWS Shield Advanced protections.
- Protecting web applications from common security threats with AWS WAF and ensuring WAF rules are applied consistently.
