### Description{% #description %}

Amazon Redshift clusters with public accessibility enabled can be accessed from the internet, creating a significant security risk by potentially exposing sensitive data to unauthorized users. By default, the `publicly_accessible` parameter is set to `true` if not explicitly defined, meaning your cluster is publicly accessible unless specifically configured otherwise. To secure your Redshift cluster, always set `publicly_accessible = false`, as shown below:

```hcl
resource "aws_redshift_cluster" "secure_example" {
  cluster_identifier = "tf-redshift-cluster"
  database_name      = "mydb"
  master_username    = "foo"
  master_password    = "Mustbe8characters"
  node_type          = "dc1.large"
  cluster_type       = "single-node"
  publicly_accessible = false
}
```

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

```terraform
resource "aws_redshift_cluster" "negative1" {
  cluster_identifier = "tf-redshift-cluster"
  database_name      = "mydb"
  master_username    = "foo"
  master_password    = "Mustbe8characters"
  node_type          = "dc1.large"
  cluster_type       = "single-node"
  publicly_accessible = false
}
```

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

```terraform
resource "aws_redshift_cluster" "positive1" {
  cluster_identifier = "tf-redshift-cluster"
  database_name      = "mydb"
  master_username    = "foo"
  master_password    = "Mustbe8characters"
  node_type          = "dc1.large"
  cluster_type       = "single-node"
}

resource "aws_redshift_cluster" "positive2" {
  cluster_identifier = "tf-redshift-cluster"
  database_name      = "mydb"
  master_username    = "foo"
  master_password    = "Mustbe8characters"
  node_type          = "dc1.large"
  cluster_type       = "single-node"
  publicly_accessible = true
}
```
