Description |
---|
Transport Layer Security (TLS) encryption is a required security setting for a private web server. This check precludes the possibility that a valid certificate has been obtained, but TLS has not been activated or is not being used. Transactions encrypted with trusted certificates are necessary when the information being transferred is not intended to be accessed by all parties on the network. |

Verify that the ssl module is loaded. Open a command prompt and run the following command from the directory where httpd.exe is located: httpd –M This will provide a list of all the loaded modules. Verify that the “ssl_module” is loaded. If this module is not found, this is a finding. After determining that the ssl module is active, locate the Apache httpd.conf file. If unable to locate the file, perform a search of the system to find the location of the file. Open the httpd.conf file with an editor such as Notepad, and search for the following uncommented directives: SSLProtocol & SSLEngine For all enabled SSLProtocol directives ensure they are set to “TLSv1”. If the SSLProtocol directive is not set to TLSv1, this is a finding. For all enabled SSLEngine directives ensure they are set to “on”. Both the SSLProtocol and SSLEngine directives must be set correctly or this is a finding. NOTE: In some cases web servers are configured in an environment to support load balancing. This configuration most likely utilizes a content switch to control traffic to the various web servers. In this situation, the TLS certificate for the web sites may be installed on the content switch vs, the individual web sites. This solution is acceptable as long as the web servers are isolated from the general population LAN. We do not want users to have the ability to bypass the content switch to access the web sites. |

Edit the httpd.conf file to load the ssl_module; set the SSLProtocol to TLSv1; and set the SSLEngine to On. |
