TMA-APACHE-7.3
Ensure the Server's Private Key Is Protected
Description
It is critical to protect the server's private key. The server's private key is encrypted by default as a means of protecting it. However, having it encrypted means that the passphrase is required each time the server is started up, and now it is necessary to protect the passphrase as well. The passphrase may be typed in when it is manually started up or provided by an automated program. Every SSLCertificateKeyFile (and any SSLCertificateFile that embeds a PRIVATE KEY) must be owned by root:root with mode 0400. 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.
