Apache HTTP Server
TMA-APACHE-5.1
Ensure Options for the OS Root Directory Are Restricted
MediaNivel 1Automatizadaapache
Descripción
The Apache Options directive allows for specific configuration of options, including execution of CGI, following symbolic links, server side includes, and content negotiation. The <Directory /> block must contain a single Options None. 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.
