# Delete a security group

Deleting a security group removes it and its rules from your account. A group can be deleted
once nothing is using it: it is detached from every resource, and it is not the default.

## Before you begin

- The group is not the default. If its **Default** column marks it, first
  [set another group as default](/myaccount/security-group/how-to/set-a-security-group-as-default/).
- Nothing is attached to the group. Select it in **Network > Security Group** and check the
  **Associated Nodes**, **Associated Scaler**, **Associated Kubernetes**, and **Associated Load
  Balancer** tabs. Detach anything listed there; for a node, see
  [Detach a security group from a node](/myaccount/security-group/how-to/detach-a-security-group-from-a-node/).

## Delete the group

A deleted group cannot be brought back, so note its rules first if you want to reuse them.

1. Open **Network > Security Group**.
2. Open the group's **Actions** menu and choose **Delete**.
3. In **Delete Security Group?**, check the name and click **Delete**.

The group leaves the list.

Your account now holds only the groups you use. If the delete is refused, [Troubleshooting Security Group](/myaccount/security-group/troubleshooting/security-group/) explains both messages.
