Manage IP address whitelists - Security Management| Alibaba Cloud Documentation Center

Background information

Multiple levels of access control, such as the multi-tenant model and security authentication mechanism, are used to ensure secure access to MaxCompute. You can pass the authentication and access and compute data based on the granted permissions only after you obtain an authorized AccessKey pair.

MaxCompute also allows you to configure an IP address whitelist to control access requests. After an IP address whitelist is configured, only the IP addresses in the whitelist are authorized to access MaxCompute projects. If you access MaxCompute projects from an IP address that is not in the whitelist, your access request is denied even if you have a valid AccessKey pair. You can configure an IP address whitelist for the classic network or a VPC in the following scenarios:

Configure an IP address whitelist for the classic network
- If you use the MaxCompute client to access a project, obtain the IP address of the device on which the MaxCompute client is deployed.
- If you use an application system to access a project, obtain the IP address of the server on which the application system is deployed.
- If you use a proxy server to access a project, obtain the IP address of the server. If you use multi-hop proxy servers to access a project, obtain the IP address of the last-hop proxy server.
- If you access MaxCompute from an Elastic Compute Service (ECS) instance, obtain the network address translation (NAT) IP address. For more information about NAT IP addresses, see EIPs.
- If you use DataWorks to submit MaxCompute jobs, you do not need to obtain the IP address of the device where DataWorks is deployed. By default, the IP address is in the whitelist.
Configure an IP address whitelist for a VPC
To configure an IP address whitelist for a VPC, perform the following steps:
- Obtain the ID of the region to which the VPC belongs and the ID of the VPC. For more information about how to obtain the region IDs and VPC IDs, see Obtain the ID of the region to which the VPC belongs and the ID of the VPC.
- Configure the endpoint of the VPC. For more information, see Endpoints.
- Add all the IP addresses of devices that need to access MaxCompute to the whitelist. For example, if you want to use services, such as Data Integration of DataWorks, Data Map of DataWorks, and Realtime Compute for Apache Flink, to access MaxCompute, you must add the IP addresses of the services to the IP address whitelist.

MaxCompute supports only project-level IP address whitelists. You can specify IP addresses in the following formats:

IPv4 or IPv6 addresses. Example: 192.168.0.0 or 2001:db8::.
IP addresses with subnet masks. Example: 172.12.0.0/16 or 2001:db8::/32.
CIDR blocks. Example: 192.168.10.0-192.168.255.255 or 2001:db8:1:1:1:1:1:1-2001:db8:4:4:4:4:4:4.

Configure an IP address whitelist

The odps.security.ip.whitelist parameter specifies the IP address whitelist for the classic network. The odps.security.vpc.whitelist parameter specifies the IP address whitelist for a VPC. For more information about the command syntax and parameters, see View the properties of a project.

You can run a command on the MaxCompute client to add the required IP addresses to an IP address whitelist.

If you configure an IP address whitelist only for the classic network, only the IP addresses in the IP address whitelist are allowed to access MaxCompute over the classic network. Access requests over VPCs are denied. Sample command:
```
setproject odps.security.ip.whitelist=192.168.0.0 odps.security.vpc.whitelist=\N;
```
When you configure an IP address whitelist for the classic network, add the IP address of the device on which the MaxCompute client is installed to the whitelist. Otherwise, your access requests are denied.
If you configure an IP address whitelist only for a VPC, only the IP addresses in the IP address whitelist are allowed to access MaxCompute over the VPC. Access requests over the classic network are denied. Sample command:
```
setproject odps.security.ip.whitelist=\N odps.security.vpc.whitelist=cn-beijing_125179[192.168.0.10,192.168.0.20];
```
If you configure IP address whitelists for both the classic network and a VPC, only the IP addresses in the IP address whitelist for the VPC are allowed to access MaxCompute over the VPC and the IP addresses in the IP address whitelist for the classic network are allowed to access MaxCompute over the classic network. Sample command:
```
setproject odps.security.ip.whitelist=192.168.0.0 odps.security.vpc.whitelist=cn-beijing_125179[192.168.0.10,192.168.0.20];
```

Note

An IP address whitelist takes effect 5 minutes after it is configured.
If your access requests are denied due to misoperations, submit a ticket to Alibaba Cloud for technical support.

View an IP address whitelist

You can run the setproject; command to view IP address whitelists. The values of the odps.security.ip.whitelist and odps.security.vpc.whitelist parameters indicate the IP addresses in the whitelists. If the odps.security.ip.whitelist or odps.security.vpc.whitelist parameter is left empty, the whitelist that corresponds to the empty parameter is not configured.

setproject;

The following result is returned:

odps.security.ip.whitelist=192.168.0.0
odps.security.vpc.whitelist=cn-beijing_125179[192.168.0.10,192.168.0.20]

Modify an IP address whitelist

You can run the setproject command to modify an IP address whitelist. After the whitelist is modified, the original IP address whitelist becomes invalid. The system controls access requests based on the new IP address whitelist.

Modify the configuration of an IP address whitelist for the classic network.
```
setproject odps.security.ip.whitelist=192.168.0.10;
```

Modify the configuration of an IP address whitelist for a VPC.

setproject odps.security.vpc.whitelist=cn-beijing_125179[192.168.10.10,192.168.0.20];

Disable the IP address whitelist feature

Run the following command to disable the IP address whitelist feature. If this feature is disabled, access requests over the classic network and the VPC are not limited.

setproject odps.security.ip.whitelist= odps.security.vpc.whitelist= ;

Note To disable the feature, you must leave the IP address whitelists for both the classic network and the VPC empty.

Configure an IP address to allow access from Alibaba Cloud services to MaxCompute

Run the following command to allow access from all Alibaba Cloud services to MaxCompute over VPCs:

setproject odps.security.ip.whitelist=192.168.0.0/16,172.16.0.0/12,10.0.0.0/8,11.0.0.0/8,33.0.0.0/8,100.64.0.0/10 odps.security.vpc.whitelist=<regionname>_*,cn_*;

odps.security.ip.whitelist: the IP address whitelist for the classic network. You do not need to change the value of this parameter in the preceding command. You can add IP addresses based on your business requirements.
regionname: the ID of the region where an Alibaba Cloud service resides.

Obtain the ID of the region to which the VPC belongs and the ID of the VPC

The following table lists the region IDs of VPCs.


Region	RegionID
China (Zhangjiakou)	cn-zhangjiakou
China (Beijing)	cn-beijing
China (Shenzhen)	cn-shenzhen
China (Chengdu)	cn-chengdu
China (Shanghai)	cn-shanghai
China (Hangzhou)	cn-hangzhou
Shanghai Tower	cn
China (Hong Kong)	cn-hongkong
Singapore (Singapore)	ap-southeast-1
Australia (Sydney)	ap-southeast-2
Malaysia (Kuala Lumpur)	ap-southeast-3
Indonesia (Jakarta)	ap-southeast-5
Japan (Tokyo)	ap-northeast-1
Germany (Frankfurt)	eu-central-1
US (Silicon Valley)	us-west-1
US (Virginia)	us-east-1
India (Mumbai)	ap-south-1
UAE (Dubai)	me-east-1
UK (London)	eu-west-1

You can use one of the following methods to obtain a VPC ID:

If this is your first time to configure an IP address whitelist for a VPC, log on to the MaxCompute client and run the following command to obtain the VPC ID:
```
whoami;
```
The following result is returned:

Note This command can be used only when the version of the MaxCompute client is V0.31.2 or later.
If you want to add an IP address to an established whitelist for a VPC, obtain the region ID from the error message returned when you use the IP address to access MaxCompute for the first time. The error message is returned because the new IP address is not authorized.
