title: Limit on IBM Cloud Object Storage public bucket access
body: <p>I am trying to create a public bucket in IBM COS, my questions are:</p>
  
  <ol>
  <li>Can we put the limit on the number of calls to the COS public bucket to avoid the DOS attack and is it required?</li>
  <li>Does IBM COS service handle it itself?</li>
  </ol>
