The security group feature of ECM is logically isolated from the public security group feature in the central cloud. Central cloud products such as CVM cannot be associated with a security group in ECM, and ECM resources such as ECM module, ECM instance, and ELB cannot be directly associated with a public security group in the central cloud. If you have already created a public security group, you can import its data, and a security group data record for ECM will be automatically generated after the import.
You can also create a security group by yourself. For more information, see Creating Security Group.
- Currently, you cannot import the security group data in finance zones or regions outside the Chinese mainland.
- Only inbound rules in the security group are imported, while the parameter template rules and nested rules will be filtered out.
