Vulnerability discussion

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 content

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

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
