Hello, friend!

A security group is a collection of access control rules for cloud servers that have the same security protection requirements and are mutually trusted in a project. The whitelist policy (allowed rules) is supported. After a security group is created, you can create different access rules for the security group to protect cloud servers in this security group.

The default security group rule does not allow access. However, you can create a rule in two security groups that can access each other. After the rule is created, ECSs in the two security groups can access each other.

Hope this helps!
