+    # The default Debian nagios4 install sets use_authentication=0 in
+    # /etc/nagios4/cgi.cfg, which turns off nagos's internal authentication.
+    # This is insecure.  As a compromise this default apache2 configuration
+    # only allows private IP addresses access.

+    # The <Files>...</Files> below shows how you can secure the nagios4
+    # web site so anybody can view it, but only authenticated users can issue
+    # commands (such as silence notifications).  To do that replace the
+    # "Require all granted" with "Require valid-user", and use htdigest
+    # program from the apache2-utils package to add users to
+    # /etc/nagios4/htdigest.users.
+    #
+    # A step up is to insist all users validate themselves by moving
+    # the stanza's in the <Files>..<Files> into the <DirectoryMatch>.
+    # Then by setting use_authentication=1 in /etc/nagios4/cgi.cfg you
+    # can configure which people get to see a particular service from
+    # within the nagios configuration.
