    • All ports open: allows inbound traffic on all ports. Note that this poses security risks.
    • Fast-add rule: You can select common protocols and ports to quickly add inbound rules. If you do not select any protocols or ports, all of them will be closed. You can add or modify security group rules as required after a security group is created.
