Check Contents

Access the Tanium Server interactively.

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

Run regedit as Administrator.

Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server

Validate the value for REG_DWORD "ForceSOAPSSLClientCert" is set to "1".

Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server

Validate the following keys exist and are configured:
REG_SZ "ClientCertificateAuthField"

For example:
X509v3 Subject Alternative Name.

REG_SZ "ClientCertificateAuthRegex"

For example-DoD:
.*\:\s*([^@]+)@.*
$Note: This regedit should be valid for any Subject Alternative Name entry.

REG_SZ "ClientCertificateAuth"
Note: This registry value defines which certificate file to use for authentication.

For example:
C:\Program Files\Tanium\Tanium Server\dod.pem

REG_SZ "cac_ldap_server_url"
Note: This registry value requires that Tanium validate every CAC/PIV authentication attempt with AD to determine the state of the account that is logging on. It must use the syntax similar to LDAP://<AD instance FQDN>

If the value for REG_DWORD "ForceSOAPSSLClientCert" is not set to "1" and the remaining registry values are not configured, this is a finding.
