Ensure Browser Framing Is Restricted

НискаНиво 2Аутоматскаapache

Опис

To prevent Clickjacking or UI Redressing attacks, it's important for the server to include an HTTP header which instructs browsers to restrict the content from being framed. There are two headers that may be used. The Content-Security-Policy header, or the X- Frame-Options header. The Header directive allows server HTTP response headers to be added, replaced or merged. Compliant when a Header always set/append Content-Security-Policy with frame-ancestors 'none' or 'self', or a Header always set/append X-Frame-Options SAMEORIGIN/DENY, is configured. 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.

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Header always append Content-Security-Policy "frame-ancestors 'self'" Then run apachectl configtest and reload Apache.
