Section Number and Name: 
N/A

Describe the issue: 

As per BZ#1566609, "In OCS 3.x, the supported way for achieving access control to volumes is enabling I/O encryption for the respective volumes, as documented in the OCS Operations Guide[1]. Further options will be considered in OCS 4."

Suggestions for improvement: 

Please include a note strongly recommending the customers to enable SSL encryption by default as stated in OCS Operations Guide[1] because as confirmed via BZ#1566609, the use of non encrypted volumes could be a security issue.
