____________________________________ - answerSingle Dedicated Server

What is the reverse proxy server located in the first layer DMZ responsible for? -
answerAnswering the incoming connection request
(and then making a connection back to the actual web server where it retrieves the
page and presents it to the requesting node)
T/F: Reverse Proxy Servers increase security - answerTrue, it places a machine with no
actual data as the most exposed serve (if the reverse proxy is breached, it contains
nothing)
T/F: Reverse proxy servers can add HTTPS level security to non-HTTPS enabled web
applications - answerTrue (the requesting node makes an HTTPS connection to the
reverse proxy server which then makes a standard HTTP connection to the actual
server)
