# Security Firewall Rule

Firewall rules allow you to permit or deny connections to or from a virtual machine (vm) based on the configuration you specify. When you create a firewall rule, you define a set of components that determine what the rule does. Components allow you to target specific traffic types, based on traffic protocols, destination ports, sources, and destinations.

Before creating a Security Firewall Rule, you must first have an Instance. If you don't have an Instance yet, you can deploy an Instance in Create VM Instance
{% endhint %}

Here are the steps to create a Security Firewall Rule:

* On your **Service Portal AI**, select the **Security** menu then click the **Create Security** button.
