The SSLCipherSuite must be configured to disable weak encryption algorithms on the Tanium Server.

Rule version TANS-SV-000044 · STIG v1 · 2018-07-09

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

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.

Fix

Access the Tanium Server interactively.

Log on with an account with administrative privileges to the server.

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:

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
