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. Satisfies: SRG-APP-000014-WSR-000006, SRG-APP-000015-WSR-000014, SRG-APP-000033-WSR-000169, SRG-APP-000179-WSR-000110, SRG-APP-000179-WSR-000111, SRG-APP-000439-WSR-000152, SRG-APP-000439-WSR-000154, SRG-APP-000439-WSR-000188, SRG-APP-000442-WSR-000182
In a command line, navigate to "<'INSTALLED PATH'>\bin". Run "httpd -M" to view a list of installed modules. If the "ssl_module" is not enabled, this is a finding. Review the <'INSTALL PATH'>\conf\httpd-ssl.conf file to determine if the "SSLProtocol" directive exists and looks like the following: SSLProtocol -SSLv2 -SSLv3 -TLSv1 +TLSv1.2 +TLSv1.3 If the directive does not exist, or exists but does not contain "-SSLv2 -SSLv3 -TLSv1 +TLSv1.2 +TLSv1.3", this is a finding.
Ensure the "ssl_module" is loaded in the "httpd.conf" file (not commented out). Ensure the "SSLProtocol" is added and looks like the following in the <'INSTALL PATH'>\conf\httpd-ssl.conf file: SSLProtocol -SSLv2 -SSLv3 -TLSv1 +TLSv1.2 +TLSv1.3 Restart the Apache service.
