Information

In the Shared Cluster, the certificate or keyfile is utilized for authentications. Implementing proper file permissions on the certificate or keyfile will prevent unauthorized access to it.

Rationale:

Protecting the certificate/keyfile strengthens authentication in the sharded cluster and prevents unauthorized access to the MongoDB database.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Set the keyFile ownership to mongodb user and remove other permissions by executing these commands:

chmod 600 /keyfile
sudo chown mongodb:mongodb /keyfile

Default Value:

Not configured
