Delete a security group

Last update: May 30 2026

Before deleting a group, you must detach it from all ports it is assigned to.

Control panel

1. Ensure you have detached the security group from all ports. You can view the list of ports with the group in the control panel: in the top menu, click Products → Cloud Servers → Security Groups → security group page → Ports.

2. In the control panel, in the top menu, click Products and select Cloud Servers.

3. Go to the Security Groups.

4. In the menu of the security group, select Delete.

5. Click Delete.

OpenStack CLI

1. Open the OpenStack CLI.

2. Delete the group separately from each port it is assigned to:

   openstack port unset \
       --security-group <security-group> \
       <port>

   Specify:

   • <security_group> — the ID or name of the security group; you can view it using the openstack security group list;
   • <port> — the ID of the port with the group; you can copy it in the control panel: in the top menu, click Products → Cloud Servers → Security Groups → security group page → Ports tab → in the UUID field, click .

3. Delete the security group:

   openstack security group delete <security_group>

   Specify <security_group> — the security group ID, which you can view using the openstack security group list.
