AWS Firewall Manager now offers customers the ability to create, deploy, and manage Amazon Virtual Private Cloud Network Access Control List (NACL) rules for their VPC subnets across all AWS organization accounts. This new feature allows customers to define policies that provide visibility into policy compliance by reporting the status of each policy.
NACL policies enable customers to establish baseline rules to safeguard their subnets, including predefined blocklist rules, which can be applied automatically across all accounts. Additionally, customers can opt to enforce NACL rules by activating automatic remediation to undo any unauthorized modifications and uphold a secure network environment.
