The enhancement enables security teams to define container attribute filters using wildcard patterns, for example, matching all containers with names starting with 'payments-'. This reduces the need for multiple individual rules for each container variant deployed in Amazon EKS and ECS environments.
Wildcard filter support addresses operational complexities of securing frequently updated container applications, ensuring comprehensive firewall coverage with fewer configurations. The feature is available in all Regions supporting Network Firewall’s container attribute inspection, facilitating scalable security management for Kubernetes and container services.
