CCI(s)

• CCI-000764 - Uniquely identify and authenticate organizational users and associate that unique identification with processes acting on behalf of those users.
• CCI-000056 - Retain the device lock until the user reestablishes access using established identification and authentication procedures.
• CCI-000166 - Provide irrefutable evidence that an individual (or process acting on behalf of an individual) falsely denying having performed organization-defined actions to be covered by non-repudiation.
• CCI-000766 - Implement multifactor authentication for network access to non-privileged accounts.
• CCI-001941 - Implement replay-resistant authentication mechanisms for access to privileged accounts and/or non-privileged accounts.
• CCI-002010 - Electronically verify Personal Identity Verification-compliant credentials from other federal agencies.
• CCI-004046 - Implement multi-factor authentication for local; network; and/or remote access to privileged accounts; and/or non-privileged accounts such that one of the factors is provided by a device separate from the system gaining access.
• CCI-004047 - Implement multi-factor authentication for local; network; and/or remote access to privileged accounts; and/or non-privileged accounts such that the device meets organization-defined strength of mechanism requirements.

Fix Recommendation

Use the vendor documentation titled "Smart card authentication" to implement correct configuration settings for this requirement.

1. Access the Tanium Server.

2. Log on to the server with an account that has administrative privileges.

3. Run regedit as Administrator.

4. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

5. Configure the value for REG_DWORD "ForceSOAPSSLClientCert" to "1".

6. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

7. Configure the following keys:

REG_SZ "ClientCertificateAuthField"
For example:
X509v3 Subject Alternative Name

REG_SZ "ClientCertificateAuthRegex"
For example-DoD:
.+?Name:\s*?(\S+@[._a-zA-Z0-9]+).*
Note: This regex may vary.

REG_SZ "ClientCertificateAuth"
For example:
E:\Program Files\Tanium\Tanium Server\cac.pem

REG_SZ "TrustedHostList"
For example:
Append 127.0.0.1 (for IPv4) and [::1] (for IPv6)

1. Access the Tanium Server.

2. Log on to the server with an account that has administrative privileges.

3. Run regedit as Administrator.

4. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

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

6. Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> WOW6432Node >> Tanium >> Tanium Server.

7. Validate the following keys exist and are configured:

REG_SZ "ClientCertificateAuthField"
For example:
X509v3 Subject Alternative Name

REG_SZ "ClientCertificateAuthRegex"
For example-DoD:
.+?Name:\s*?(\S+@[._a-zA-Z0-9]+).*
Note: This regex may vary.

REG_SZ "ClientCertificateAuth"
For example:
E:\Program Files\Tanium\Tanium Server\cac.pem

REG_SZ "TrustedHostList"
For example:
127.0.0.1 (for IPv4) and [::1] (for IPv6)

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