Can I Modify the Security Group of a GaussDB(DWS) Cluster?

Yes. When a data warehouse cluster is created, its security group cannot be changed. However, you can add, delete, or modify rules of the current security group.

To edit the cluster security group:

1. Log in to the GaussDB(DWS) management console.
2. In the navigation pane on the left, click Clusters.
3. In the cluster list, find the target cluster and click the cluster name. The Basic Information page is displayed.
4. Locate the Security Group parameter and click the security group name to switch to the Security Groups page on the VPC console, on which you can set the security group.
