Changing the Security Group of an ECS


Change the security group associated with an ECS NIC.


  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. Under Computing, click Elastic Cloud Server.
  4. On the Elastic Cloud Server page, click the name of the target ECS.
  5. Click the Security Groups tab. Then, click Change Security Group.
  6. Select the new security group to be associated with the ECS NIC.

    You can select multiple security groups. In such a case, the access rules of all the selected security groups apply to the ECS.


    Using multiple security groups may deteriorate ECS network performance. We recommend that you select no more than five security groups for each ECS.

  7. Click OK.
