Overview

Service Overview

A Security Group is a virtual logical firewall that controls inbound/outbound traffic generated on virtual servers in Samsung Cloud Platform. The resources that can have a Security Group applied include Virtual Server, Database, Kubernetes Engine, etc. A Security Group is applied to the ports of the target resource, and multiple Security Groups can be applied depending on each resource’s characteristics.

When you first create a Security Group, it blocks all inbound and outbound traffic according to the default rule (Any/Deny).

Users can specify an IP address, port, and protocol to create inbound/outbound rules, and only traffic allowed by the created rules can access the target resources.
