### Description{% #description %}

Containers must not run with root privileges. The PodSecurityPolicy must set `privileged` and `allow_privilege_escalation` to `false`, and `spec.run_as_user.rule` must be `MustRunAsNonRoot`. The group settings `fs_group` and `supplemental_groups` must use `MustRunAs` and their `range.min` must not allow `0` (root).

Noncompliant policies permit privilege escalation or root user/group IDs, increasing the risk of container breakout and unauthorized host access; this rule identifies PSPs that do not enforce these restrictions.

## Compliant Code Examples{% #compliant-code-examples %}

```terraform
resource "kubernetes_pod_security_policy" "example2" {
  metadata {
    name = "terraform-example"
  }
  spec {
    privileged                 = false
    allow_privilege_escalation = false

    volumes = [
      "configMap",
      "emptyDir",
      "projected",
      "secret",
      "downwardAPI",
      "persistentVolumeClaim",
    ]

    run_as_user {
      rule = "MustRunAsNonRoot"
    }

    se_linux {
      rule = "RunAsAny"
    }

    supplemental_groups {
      rule = "MustRunAs"
      range {
        min = 1
        max = 65535
      }
    }

    fs_group {
      rule = "MustRunAs"
      range {
        min = 1
        max = 65535
      }
    }

    read_only_root_filesystem = true
  }
}
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```terraform
resource "kubernetes_pod_security_policy" "example" {
  metadata {
    name = "terraform-example"
  }
  spec {
    privileged                 = true
    allow_privilege_escalation = true

    volumes = [
      "configMap",
      "emptyDir",
      "projected",
      "secret",
      "downwardAPI",
      "persistentVolumeClaim",
    ]

    run_as_user {
      rule = "RunAsAny"
    }

    se_linux {
      rule = "RunAsAny"
    }

    supplemental_groups {
      rule = "RunAsAny"
      range {
        min = 1
        max = 65535
      }
    }

    fs_group {
      rule = "MustRunAs"
      range {
        min = 0

      }
