Do I Need to Enable Private Network Access Control for a Load Balancer After Setting a Security Group?

You can access a GeminiDB Redis instance through a node or load balancer. Therefore, you need to configure both a security group and private network access control for a load balancer to ensure instance security.

• Security groups take effect only for nodes. It is a collection of access control rules for ECSs and GeminiDB Redis instances that have the same security requirements and are mutually trusted in a VPC. For details, see Configuring Security Group Rules.
• Security groups cannot take effect for load balancers. If access control is disabled, all IP addresses that can access the VPC of the GeminiDB Redis instance also can access the instance using a load balancer IP address. Therefore, you need to configure access control properly. For details, see Enabling or Disabling Private Network Access for a Load Balancer.
