Common security group rules
A rule can be configured to allow any address to access the KEC instance. The rule may cause security risks. It is recommended that you configure security group rules as needed.
A rule can be configured to allow external resources to access the specified port of the KEC instance. For example, if a Linux KEC instance requires SSH, set the protocol to TCP, port to 22, and source IP address to 0.0.0.0/0. You can create such a rule to meet common requirements.
A rule can be configured to allow only specified IP addresses to access the specified port of the KEC instance. For example, the following figure represents that only 120.1.2.3/32 can access port 22 of the KEC instance. You can create such a rule to meet advanced requirements.
