In today’s cloud landscape, organizations leverage AWS Network Firewall to protect their workloads from prevalent security threats. However, many still depend on external threat feeds and scanners that may lack comprehensive visibility into AWS environments, leaving them vulnerable to active threats. A self-managed approach utilizing traditional threat intelligence and custom rules may lead to potential gaps in security defenses.
AWS is committed to enhancing active defense mechanisms to empower customers. In previous posts on this blog, we discussed our internal active defense systems, such as global honeypots and neural networks designed to monitor and respond to threats effectively.
Key Features of AWS Network Firewall
One of the notable features of AWS Network Firewall is its capability to offer flow management, which significantly bolsters network security. This managed, stateful firewall service enables users to set detailed rules for controlling VPC network traffic. The latest enhancements include flow capture and flow flush functionalities that improve visibility into network activities, ensuring effective policy enforcement.
AWS Network Firewall has also introduced an automated domain lists feature that enhances security for outbound traffic. By analyzing HTTP and HTTPS traffic patterns, organizations can gain insights into domain usage and streamline the management of outbound controls through domain-based allowlisting.
Additionally, AWS Network Firewall ensures high availability through session state replication, optimizing application traffic management. This managed service allows for the implementation of firewall rules that provide meticulous control over network traffic, including both incoming and outgoing communications.
Enhanced Monitoring and Compliance
To further enhance monitoring capabilities, the AWS Network Firewall CloudWatch Dashboard offers customizable pages within the CloudWatch console, allowing for a comprehensive view of resource performance. This tool is essential for deriving deeper insights into firewall operations and ensuring compliance with security protocols.
The recent Geographic IP Filtering feature empowers customers to filter traffic based on geographic locations, fulfilling compliance requirements and enhancing overall security posture. As organizations navigate the complexities of network security, it becomes imperative to keep firewall rules updated with the latest features available in AWS Network Firewall.
