How Can I Configure Security Group Rules?

Security group rules consist of inbound and outbound rules.

When adding an inbound rule, you can set the source address to a security group or CIDR block. If you want to set the source address to a security group, you can only select security groups from the same VPC as the destination security group.

When adding an outbound rule, you can set the destination address to a security group or CIDR block. If you want to set the destination address to a security group, you can only select security groups from the same VPC as the source security group.

ECSs in security groups in different VPCs cannot communicate with one another. To allow them to communicate, bind EIPs to them and configure security group rules.


What Is a Security Group?
