ACL

The ACL tab of the Security Settings page provides the IP Address Ranges, IPv4 CIDR Blocks, and VPC Endpoints settings for allowing user access only from specified IP address ranges, IPv4 CIDR blocks, or VPC endpoints.

Only the administrator can configure the ACL. If an IAM user needs to configure the ACL, the user can request the administrator to perform the configuration or grant the required permissions.

Access type:

Console Access (recommended): The ACL takes effect only for IAM users who are created using your account and have access to the console.
API Access: The ACL controls users' API access through API Gateway and takes effect only for IAM users two hours after you complete the configuration.

You can configure a maximum of 200 access control items.

IP Address Ranges

Specify IP address ranges from 0.0.0.0 to 255.255.255.255 to allow access to the cloud platform. The default value is 0.0.0.0–255.255.255.255. If this parameter is left blank or the default value is used, your IAM users can access the management console from anywhere.

IPv4 CIDR Blocks

Specify IPv4 CIDR blocks to allow access to the cloud platform. For example, set IPv4 CIDR block to 10.10.10.10/32.

VPC Endpoints

Specify access to the cloud platform APIs only from the VPC endpoint with the specified ID, for example, 0ccad098-b8f4-495a-9b10-613e2a5exxxx. You can set the VPC endpoint only on the API Access tab. If access control is not configured, you can access APIs from all VPC endpoints by default.

User access is allowed if any of IP Address Ranges, IPv4 CIDR Blocks, and VPC Endpoints is met.
