# stackit_security_group_rule (Resource)

Security group rule resource schema. Must have a `region` specified in the provider configuration.

## Example Usage

```terraform

  project_id        = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  security_group_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
  direction         = "ingress"
  icmp_parameters = {
    code = 0
    type = 8
  }
  protocol = {
    name = "icmp"
  }
