### Description{% #description %}

OSS buckets should have public access disabled. This rule flags `alicloud_oss_bucket` resources where `acl` is set to `public-read` or `public-read-write`. To restrict access, set `acl = "private"` or remove the `acl` attribute.

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

```terraform
resource "alicloud_oss_bucket" "bucket_public_access_enabled1" {
  bucket = "bucket-170309-acl"
  acl    = "private"
}
```

```terraform
resource "alicloud_oss_bucket" "bucket_public_access_enabled4" {
  bucket = "bucket-170309-acl"
}
```

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

```terraform
resource "alicloud_oss_bucket" "bucket_public_access_enabled2" {
  bucket = "bucket-170309-acl"
  acl    = "public-read"
}
```

```terraform
resource "alicloud_oss_bucket" "bucket_public_access_enabled3" {
  bucket = "bucket-170309-acl"
  acl    = "public-read-write"
}

resource "alicloud_oss_bucket" "bucket-logging" {
  bucket = "bucket-170309-logging"

  logging {
    target_bucket = alicloud_oss_bucket.bucket-target.id
    target_prefix = "log/"
  }
}
```
