Section Number and Name: 
Security Guide - 2.6.6. Hot Rod Interface Security
Security Guide - 2.6.7. User Authentication over Hot Rod Using SASL
Admin Guide - 11.7. REST Interface Security
Admin Guide - 12.4. Memcached Interface Security

Describe the issue: 
Information on securing JDG remote interfaces is spread out, in multiple documents.
Depending on which interface you're trying to secure and which document you look at, you'll either find the information, or not even a reference.

This will likely lead customers to believe an interface cannot be secured, when there are details for other interfaces in that document, but not even a reference to securing that interface.

Suggestions for improvement: 
The documentation for securing Hot Rod, REST, and memcached should all be in the same area of the same document.  A link should be included in the other document in the relevant section.
