1925     # The default Debian nagios4 install sets use_authentication=0 in
1926     # /etc/nagios4/cgi.cfg, which turns off nagos's internal authentication.
1927     # This is insecure.  As a compromise this default apache2 configuration
1928     # only allows private IP addresses access.
1929     #
1930     # The <Files>...</Files> below shows how you can secure the nagios4
1931     # web site so anybody can view it, but only authenticated users can issue
1932     # commands (such as silence notifications).  To do that replace the
1933     # "Require all granted" with "Require valid-user", and use htdigest
1934     # program from the apache2-utils package to add users to
1935     # /etc/nagios4/htdigest.users.
1936     #
1937     # A step up is to insist all users validate themselves by moving
1938     # the stanza's in the <Files>..<Files> into the <DirectoryMatch>.
1939     # Then by setting use_authentication=1 in /etc/nagios4/cgi.cfg you
1940     # can configure which people get to see a particular service from
1941     # within the nagios configuration.
