Ensure ServerTokens is Set to 'Prod' or 'ProductOnly'

낮음레벨 1자동apache

설명

Configure the Apache ServerTokens directive to provide minimal information. By setting the value to Prod or ProductOnly. The only version information given in the server HTTP response header will be Apache rather than details on modules and versions installed. The effective (last) ServerTokens must be Prod or ProductOnly; the default Full fails. Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file.
