# 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. {% hint style="warning" %} 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 **Cloudeka Portal**, select the **Security** menu then click the **Create Security** button.

* Fill in the Create Security form:

Column	Description
Name	Name of your security.
Inbound Rule	Define the traffic allowed to the instance on which ports and from which sources.
Outbound Rule	Define the traffic allowed to leave the instance on which ports and to which destinations.

* Click **Delete** button to delete the security. Select **Apply to Instance** (for the instance where Security is created), Click the **Save** button if you want to continue creating the firewall or **Cancel** if you don't want to continue the process.

* There will be a notification if the Firewall has been successfully created **"Firewall has been successfully created"**.
