A Cheat Sheet to Database Access Control: MongoDB

MongoDB is a popular open source NoSQL database management system. This document-oriented database is designed to provide a flexible, scalable, high-performance solution for handling large volumes of unstructured or semi-structured data. MongoDB stores data in a flexible, JSON-like format called BSON (Binary JSON) that can represent complex structures and relationships. Unlike traditional relational databases, MongoDB is schema-less, meaning that each document in a collection can have a different structure. This flexibility allows developers to adapt the data model easily as application requirements evolve. MongoDB is widely used in modern web development, especially in scenarios where flexibility and scalability are critical. Its document-oriented approach and features make it suitable for a variety of applications, ranging from content management systems and e-commerce platforms to real-time analytics and Internet of Things (IoT) solutions. For part two of our how-to series on access management for the most commonly used databases in today’s cloud environments, we’ll do a deep dive into MongoDB, including a cheat sheet to all MongoDB access commands. Don’t miss the first article in this series, which looks at access control in MySQL.

Why You Need to Manage Access to MongoDB

Managing access to MongoDB is crucial for security, data integrity and regulatory compliance.

• Prevent unauthorized access: Not carefully controlling access to a MongoDB database can allow unauthorized individuals or systems to gain entry to the database, potentially enabling them to view, modify or delete sensitive data.
• Secure confidential information: MongoDB databases often store sensitive information, including personal user data, financial records or proprietary business data. Managing access helps ensure that only authorized personnel have the necessary permissions to interact with and retrieve this confidential information.
• Achieve consistency: Improperly managed access can lead to data corruption or inconsistency. Access controls help enforce data integrity by preventing unauthorized users from making changes to the database so that the data remains accurate and reliable.
• Meet regulatory standards: Many industries and regions have specific data protection and privacy regulations that mandate proper access controls. Managing access to MongoDB is essential for compliance with standards such as GDPR, the Health Insurance Portability and Accountability Act (HIPAA) and the Payment Card Industry Data Security Standard (PCI DSS).
• Provide audit trails: It is critical for organizations to monitor who accesses the database, when and what actions they perform. These audit trails are often required for compliance and can assist with forensic investigations after a security incident.
• Reduce breach risks: Compromised MongoDB databases can be targets for malicious actors seeking to steal sensitive data or disrupt operations. Effective access management helps decrease the risk of data breaches by controlling and monitoring who has access to the database.
• Improve operational efficiency: By granting users the appropriate level of access based on their roles and responsibilities, organizations can enable employees to perform their duties without unnecessary bottlenecks or privileges.
• Segregate duties: By implementing the principle of least privilege, organizations can grant users only the permissions necessary for their specific tasks. Segregating duties in this way helps prevent misuse of privileges.

What to Consider When Controlling Access to MongoDB

When looking for a tool to help with MongoDB access management, you’ll want to consider various factors that help ensure the database’s security, integrity and efficiency.

• MongoDB integration: Access control tools should seamlessly integrate with MongoDB‘s native authentication and authorization mechanisms.
• Access control granularity: Fine-grained access controls allow you to define roles with specific permissions to adhere to the principle of least privilege.
• Custom role capabilities: The ability to create custom roles allows you to tailor permissions based on your MongoDB deployment’s requirements.
• User-friendly interface: An intuitive interface for configuring and managing access controls can simplify defining roles, managing users and requesting access, even through familiar platforms like Slack with Apono.
• Dynamic, automated access controls: Tools that support automation allow you to manage access controls dynamically, which is especially important for organizations with rapidly changing environments.
• Audit trails: Robust auditing features help you generate comprehensive audit trails, capturing details about access requests, user activity and administrative changes.
• Scalability: The access control tool must be able to scale efficiently with your MongoDB deployment.
• Onboarding ease: A tool that streamlines the onboarding process makes it easier for administrators to understand and manage access controls.

A MongoDB Cheat Sheet for All Commands to Control Access

Here’s a quick reference cheat sheet for MongoDB access control commands:

• Create a new user.

  use admin
  db.createUser({
    user: "username",
    pwd: "password",
    roles: [
      { role: "readWrite", db: "yourDatabase" },
      // Additional roles if needed
    ]
  })
  

• Grant role to an existing user.

  use admin
  db.grantRolesToUser("username", [{ role: "read", db: "anotherDatabase" }])
  

• Create custom role.

  use admin
  db.createRole({
    role: "customRole",
    privileges: [
      { resource: { db: "yourDatabase", collection: "" }, actions: ["find", "update"] },
      // Additional privileges if needed
    ],
    roles: []
  })
  

• Grant custom role to an existing user.

  use admin
  db.grantRolesToUser("username", [{ role: "customRole", db: "yourDatabase" }])
  

• Revoke role from user.

  use admin
  db.revokeRolesFromUser("username", ["readWrite"])
  

• View roles for user.

  use admin
  db.getUser("username").roles
  

Conclusion

MongoDB comes with an impressive set of access and security capabilities. However, new and improved attack vectors and the continuous drive to improve productivity underscore the value of a dedicated database access management solution.
