Creating a Network ACL

Function

A network ACL is an optional layer of security for your subnets. You can add inbound and outbound rules to a network ACL and associate subnets with it to control traffic in and out of the subnets.

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.
