| Access the Tanium Server interactively. Log on to the server with an account that has administrative privileges. Access the server's registry by typing: "regedit". Click "Enter". Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server. Verify the existence of a String "SSLCipherSuite" with a value of: ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK If the String "SSLCipherSuite" does not exist with the appropriate list values, this is a finding. |
