Ensure HTTP Strict Transport Security Is Enabled

低レベル 2自動apache

説明

HTTP Strict Transport Security (HSTS) is an optional web server security policy mechanism specified by an HTTP Server header. The HSTS header allows a server declaration that only HTTPS communication should be used rather than clear text HTTP communication. At least one Header directive must set Strict-Transport-Security and every such header must have max-age of 480 seconds or more. 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. CIS marks this recommendation Manual; the automated check implements its audit procedure.

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

Header always set Strict-Transport-Security "max-age=600" (at server level and in each TLS virtual host). Then run apachectl configtest and reload Apache.
