How can you secure a MongoDB database?

Securing a MongoDB database is fundamentally centered around the implementation of authentication, authorization, and encryption. Each of these components plays a critical role in safeguarding the database against unauthorized access and data breaches.

Authentication is the first line of defense, requiring users to provide valid credentials before they can interact with the database. This ensures that only legitimate users can access the system.

Authorization determines what actions authenticated users are allowed to perform. By using role-based access control, MongoDB allows administrators to assign specific permissions to users, ensuring that they can only access the data needed for their role. This principle of least privilege is essential for maintaining security within the database.

Encryption adds another layer of security by protecting data at rest and in transit. This means that sensitive data stored in the database is encrypted, making it unreadable to anyone who does not have the proper decryption keys. Similarly, encrypting data as it travels over the network helps prevent eavesdropping and man-in-the-middle attacks.

While the other choices may seem relevant, they do not specifically address the technical measures necessary for securing a database. Complex data structures do not inherently provide security benefits, user training and support are important for overall security awareness but are not a direct means of securing the database itself, and
