CCSS (Common Configuration Scoring System) is a set of measures used to determine the severity of the rule.
Each rule is associated with a high-level category. For example IAM, Container, Monitoring, Logging, Network, etc.
In a few clicks we can analyze your entire application and see what components are vulnerable in your application, and suggest you quick fixes.
Test your applicationsObject-level S3 events (GetObject, DeleteObject, and PutObject) are not logged by default, though this is recommended from a security best practices perspective for buckets that contain sensitive data.
Configure the aws_cloudtrail event_selector block with appropriate settings.
The event_selector block should contain:
type set to AWS::S3::Object and values set to either the ARN for the aws_s3_bucket, or arn:aws:s3::: to apply to all buckets.All or ReadOnly.Example configuration:
resource "aws_s3_bucket" "bucket1" {
  # other required fields here
}
resource "aws_s3_bucket" "logged_bucket1" {
  # other required fields here
}
resource "aws_cloudtrail" "read_write_type_all" {
  name = "read_write_type_all"
  s3_bucket_name = "${aws_s3_bucket.ct_bucket1.id}"
  event_selector {
    read_write_type = "All"
    data_resource {
      type = "AWS::S3::Object"
      values = ["${aws_s3_bucket.ct_bucket1.arn}/", "${aws_s3_bucket.logged_bucket1.arn}/"]
    }
  }
}
Configure the AWS::CloudTrail::Trail EventSelector block with appropriate settings.
The EventSelector block should contain:
Type set to AWS::S3::Object and Values set to the ARN for the AWS::S3::BucketAll or ReadOnlyExample configuration:
