Description

AWS provides a support center that may need access to an AWS account to help manage incidents. To implement least privilege for access control, an IAM role should be created with the managed 'AWSSupportAccess' IAM policy attached.

How to fix?

Use an aws_iam_policy_attachment or aws_iam_role_policy_attachment to attach the AWS managed policy AWSSupportAccess to an aws_iam_role by using an ARN similar to arn:aws:iam::aws:policy/AWSSupportAccess.

Example Configuration

Using an aws_iam_policy_attachment:

resource "aws_iam_role" "main" {
  name = "rm_2072"

  assume_role_policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": "sts:AssumeRole",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Effect": "Allow",
      "Sid": ""
    }
  ]
}
EOF
}

resource "aws_iam_policy_attachment" "main" {
  name       = "main"
  roles      = [aws_iam_role.main.name]
  policy_arn = "arn:aws:iam::aws:policy/AWSSupportAccess"
}

Using an aws_iam_role_policy_attachment:

resource "aws_iam_role" "main" {
  name = "rm_2072"

  assume_role_policy = <<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": "sts:AssumeRole",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Effect": "Allow",
      "Sid": ""
    }
  ]
}
EOF
}

resource "aws_iam_role_policy_attachment" "main" {
  role       = "${aws_iam_role.main.name}"
  policy_arn = "arn:aws:iam::aws:policy/AWSSupportAccess"
}
