An Apache web server must maintain the confidentiality of controlled information during transmission through the use of an approved TLS version.

Transport Layer Security (TLS) is a required transmission protocol for a web server hosting controlled information. The use of TLS provides confidentiality of data in transit between the web server and client. FIPS 140-2 approved TLS versions must be enabled and non-FIPS-approved SSL versions must be disabled. NIST SP 800-52 defines the approved TLS versions for government applications.

Check Text ( C-15607r277929_chk )
In a command line, navigate to "<'INSTALLED PATH'>\bin". Run "httpd -M" to view a list of installed modules.

If the module "mod_ssl" is not enabled, this is a finding.

Review the <'INSTALLED PATH'>\conf\httpd.conf file to determine if the "SSLProtocol" directive exists and looks like the following:

SSLProtocol -ALL +TLSv1.2

If the directive does not exist and does not contain "-ALL +TLSv1.2", this is a finding.
Fix Text (F-15605r277930_fix)
Ensure the "SSLProtocol" is added and looks like the following in the <'INSTALLED PATH'>\conf\httpd.conf file:

SSLProtocol -ALL +TLSv1.2

Ensure the "SSLEngine" parameter is set to "ON" inside the "VirtualHost" directive.
