Description

CloudFront access logs record information about every user request that CloudFront receives. CloudFront distribution access logging should be enabled in order to track viewer requests for content, analyze statistics, and perform security audits.

How to fix?

Set the logging_config block with a valid bucket.

Example Configuration

resource "aws_cloudfront_distribution" "s3_distribution" {
  origin {
    domain_name = "${aws_s3_bucket.b.bucket_regional_domain_name}"
    origin_id   = "${aws_s3_bucket.b.id}"

    s3_origin_config {
      origin_access_identity = "${aws_cloudfront_origin_access_identity.origin_access_identity.cloudfront_access_identity_path}"
    }
  }

  logging_config {
    bucket = "${aws_s3_bucket.b-logs.bucket_regional_domain_name}"
  }

  enabled = true
  
  restrictions {
    geo_restriction {
      restriction_type = "whitelist"
      locations        = ["US", "CA", "GB", "DE"]
    }
  }

  viewer_certificate {
    cloudfront_default_certificate = true
  }

  default_cache_behavior {
    allowed_methods  = ["DELETE", "GET", "HEAD", "OPTIONS", "PATCH", "POST", "PUT"]
    cached_methods   = ["GET", "HEAD"]
    target_origin_id = "${aws_s3_bucket.b.id}"

    forwarded_values {
      query_string = false

      cookies {
        forward = "none"
      }
    }

    viewer_protocol_policy = "redirect-to-https"
    min_ttl                = 0
    default_ttl            = 3600
    max_ttl                = 86400
  }
}
