> These cluster options are only available for [clusters in which Rancher has launched Kubernetes](../../new-user-guides/kubernetes-clusters-in-rancher-setup/launch-kubernetes-with-rancher/launch-kubernetes-with-rancher.md).
You can always assign a pod security policy (PSP) to an existing project if you didn't assign one during creation.
### Prerequisites
- Create a Pod Security Policy within Rancher. Before you can assign a default PSP to an existing project, you must have a PSP available for assignment. For instruction, see [Creating Pod Security Policies](../authentication-permissions-and-global-configuration/create-pod-security-policies.md).
- Assign a default Pod Security Policy to the project's cluster. You can't assign a PSP to a project until one is already applied to the cluster. For more information, see [the documentation about adding a pod security policy to a cluster](../manage-clusters/add-a-pod-security-policy.md).
### Applying a Pod Security Policy
1. From the **Global** view, find the cluster containing the project you want to apply a PSP to.
1. From the main menu, select **Projects/Namespaces**.
1. Find the project that you want to add a PSP to. From that project, select **&#8942; > Edit**.
1. From the **Pod Security Policy** drop-down, select the PSP you want to apply to the project.
Assigning a PSP to a project will:
- Override the cluster's default PSP.
- Apply the PSP to the project.
- Apply the PSP to any namespaces you add to the project later.
1. Click **Save**.
**Result:** The PSP is applied to the project and any namespaces added to the project.
>**Note:** Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked to determine if they comply with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.
