Chp 3 discussion – security architecture and design course

What happens when we place the authentication system in our demilitarized zone (DMZ)—that is, in the layer closest to the Internet? What do we have to do to protect the authentication system? Does this placement facilitate authentication in some way? How about if we move the authentication system to a tier behind the DMZ, thus, a more trusted zone? What are the implications of doing so for authentication performance? For security? 

Answer the question with a short paragraph, with a minimum of 300 words.  APA formatting but do not include a title page, abstract or table of contents. Body and references only in your post. 

A minimum of two references are required.  One reference for the book is acceptable but multiple references are allowed.  There should be multiple citations within the body of the post.  Note that an in-text citation includes author’s name, and year of publication.
