SV-93545r1_rule The SSLCipherSuite must be configured to disable weak encryption algorithms on the Tanium Server.

Vulnerability discussion

Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated.

Check content

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.

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.
