If passwords are used for authentication, MongoDB must transmit only encrypted representations of passwords.

The DOD standard for authentication is DOD-approved PKI certificates.

Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires authorizing official (AO) approval.

In such cases, passwords need to be protected at all times, and encryption is the standard method for protecting passwords during transmission.

DBMS passwords sent in clear text format across the network are vulnerable to discovery by unauthorized users. Disclosure of passwords may easily lead to unauthorized access to the database.

In the MongoDB database configuration file (default location /etc/mongod.conf), verify the following parameters in the "net.tls" (network TLS) section of the file:

net: tls: mode: requireTLS certificateKeyFile: /etc/ssl/server.pem CAFile: /etc/ssl/ca.crt allowInvalidCertificates: false allowConnectionsWithoutCertificates: false

If the "net.tls" parameter is not present, this is a finding.

If the "net.tls.certificateKeyFile" parameter is not present, this is a finding.

If the "net.tls.CAFile" parameter is not present, this is a finding.

If the "net.tls.allowInvalidCertificates" parameter is found and set to "true", this is a finding.

If the "net.tls.allowConnectionsWithoutCertificates" parameter is found and set to "true", this is a finding.

In the MongoDB database configuration file (default location /etc/mongod.conf), ensure the following parameters are present in the "net.tls" (network TLS) section of the file and are configured correctly for the site and server:

net: tls: mode: requireTLS certificateKeyFile: /etc/ssl/server.pem CAFile: /etc/ssl/ca.crt allowInvalidCertificates: false allowConnectionsWithoutCertificates: false

Restart the MongoDB service from the OS.

$ sudo systemctl restart mongod
