| Access the Tanium Server interactively. Log on with an account with administrative privileges to the server. 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: AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-CCM:AES128-CCM:AES256- CCM8:AES128-CCM8:AES256-SHA256:AES128- SHA256:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3- SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA If the String "SSLCipherSuite" does not exist with the appropriate list values, this is a finding. |
