Security Groups in QCloud are a set of firewall rules that control inbound and outbound traffic to virtual instances. Customers can create and manage Security Groups to define network access policies for their infrastructure.
Security Groups help control access to instances by defining traffic rules. Customers can create groups, configure rules, and restrict or allow traffic as per their security policies.
