MongoDB must include only approved trust anchors in trust stores or certificate stores managed by the organization.

Public key infrastructure (PKI) certificates are certificates with visibility external to organizational systems and certificates related to the internal operations of systems, such as application-specific time services. In cryptographic systems with a hierarchical structure, a trust anchor is an authoritative source (i.e., a certificate authority) for which trust is assumed and not derived. A root certificate for a PKI system is an example of a trust anchor. A trust store or certificate store maintains a list of trusted root certificates.

Check the MongoDB configuration file (default location /etc/mongod.conf) for a key named "net.tls.CAFile".

Example shown below:

net: tls: mode: requireTLS certificateKeyFile: /etc/ssl/mongodb.pem CAFile: /etc/ssl/caToValidateClientCertificates.pem ocsp: enabled: true responderURL: <your organization's OCSP responder URL>

If this key is not found, this is a finding.

Edit the MongoDB configuration file (default location /etc/mongod.conf) and add a key named "net.tls.CAFile" to configure the certificate trust.

Example shown below:

net: tls: mode: requireTLS certificateKeyFile: /etc/ssl/mongodb.pem CAFile: /etc/ssl/caToValidateClientCertificates.pem ocsp: enabled: true responderURL: <your organization's OCSP responder URL>
