TMA-APACHE-4.3
Ensure OverRide Is Disabled for the OS Root Directory
Descripción
The Apache AllowOverRide directive and the new AllowOverrideList directive allow for .htaccess files to be used to override much of the configuration, including authentication, handling of document types, auto generated indexes, access control, and options. The <Directory /> block must contain a single AllowOverride None and no AllowOverrideList. 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.
