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

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-253862	TANS-SV-000044	SV-253862r850365_rule		Medium

Description
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.

1. Access the Tanium Server. 2. Log on to the server with an account that has administrative privileges. 3. Access the server's registry by typing: "regedit". 4. Click "Enter". 5. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server. 6. Verify the existence of the 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.
