Chapter #6 from textbook

The network restrictions surrounding the web authentication service is one layer of defense. Is that sufficient? 

Answer the question with a short paragraph, with a minimum of 400 words. Count the words only in the body of your response, not the references.  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.
