Keep your firewall rules up-to-date with Network Firewall features
- AWS Network Firewall is a managed firewall service for VPCs on AWS.
- Network Firewall automatically scales with traffic and allows fine-grained control over network traffic.
- The article explains the mechanisms that Network Firewall uses to assist in keeping your rule sets current and effective.
- Three features – managed rule groups, prefix lists, and tag-based resource groups – are discussed in detail.
- Managed rule groups are predefined, updated rules managed by AWS to protect against evolving security threats.
- Prefix lists simplify firewall management with IP address ranges that are managed by AWS or customers.
- Tag-based resource groups simplify firewall management by applying stateful rules to resources that meet certain EC2 or ENI tag criteria.
- AWS handles much of the work associated with keeping security rules synchronized, reducing manual intervention and customer automation processes.
- Managed rule groups, prefix lists, and tag-based resource groups can enhance the efficiency and effectiveness of your Network Firewall deployments.
- If you have questions about Network Firewall, contact AWS Support.
