Check: TANS-SV-000044

Tanium 7.3 STIG: TANS-SV-000044 (in versions v2 r2 through v1 r1)

Title

The SSLCipherSuite must be configured to disable weak encryption algorithms on the Tanium Server. (Cat II impact)

Discussion

Use of weak or untested encryption algorithms undermines the purposes of utilizing 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 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.

Fix Text

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 <enter>. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server. Add or modify the String "SSLCipherSuite" to have 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
