AS24-W2-000030_rule 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.

Vulnerability discussion

The 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.

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 "SSLProtocol" 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.
