AS24-U2-000030 - The Apache web server must use encryption strength in accordance with the categorization of data hosted by the Apache web server when remote connections are provided - SSLProtocol

Information

The Apache web server has several remote communications channels. Examples are user requests via http/https, communication to a backend database, and communication to authenticate users. The encryption used to communicate must match the data that is being retrieved or presented.

Methods of communication are 'http' for publicly displayed information, 'https' to encrypt when user data is being transmitted, VPN tunneling, or other encryption methods to a database.

Solution

Determine the location of the 'HTTPD_ROOT' directory and the 'httpd.conf' file:

# httpd -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT='/etc/httpd'
-D SERVER_CONFIG_FILE='conf/httpd.conf'

Ensure the 'SSLProtocol' is added and looks like the following:

SSLProtocol -ALL +TLSv1.2

Restart Apache: apachectl restart
