# Security and User Management

You can add user groups and assign permissions for Public and Private Node Pools with the **Kubernetes Manager** in [<mark style="color:blue;">DCD</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#data-center-designer-dcd).

{% tab title="Public Node Pools" %}
In the clusters for Public Node Pools, nodes only have external IP addresses, which means that the nodes and pods are exposed to the internet.

### Set up security settings

To set up the security settings, follow these steps:

1. In the **DCD**, go to **Menu** > **Containers** > **Managed Kubernetes**.
2. In **Kubernetes Manager**, select a cluster.
3. Go to the **Security** tab and click **Visible to Groups**.
4. To enable access, select the **Edit** or **Share** checkbox for a group.

{% hint style="info" %}
**Note:** To disable access, select the group for which you want to disable access. Clear either the **Edit** or **Share** checkboxes. You can also directly click **Remove Group**.
{% endhint %}

{% hint style="success" %}
**Result:** The cluster for Public Node Pools now has the newly assigned permissions.
{% endhint %}
{% endtab %}

{% tab title="Private Node Pools" %}
In the clusters for Private Node Pools, nodes only have internal IP addresses, which means that the nodes and pods are isolated from the internet. Internal IP addresses for nodes come from the primary IP address range of the subnet you choose for the cluster.
