What is MQTT Security?

MQTT Security encompasses the practices, protocols, and technologies designed to safeguard IoT data transmitted using the MQTT (Message Queuing Telemetry Transport) protocol. As a lightweight and widely adopted protocol in IoT/IIoT implementations, ensuring the security of data transmitted via MQTT is crucial. By implementing robust MQTT security, organizations can prevent unauthorized access, data breaches, and other potential threats in their IoT ecosystems, ensuring the reliable and secure operation of their connected devices.

Core aspects of MQTT Security

Given the critical importance of security in the IoT environment, several core aspects of MQTT security are essential. These include:

Authentication

Ensuring that the identities of devices and users are verified before they are granted access to the network.

Encryption

Safeguarding data to prevent it from being read or compromised by unauthorized entities.

Access control

Preserving the integrity and confidentiality of data by controlling who is allowed to publish or subscribe to specific topics.

Session Expiry and Timeout

Setting time limits on sessions and connections to reduce the risk of unauthorized access after a period of inactivity.

Why does the Internet of Things need top-notch security?

As a wide range of devices, from home appliances to industrial machines, become interconnected and exchange data over networks, the risk of data breaches and other security threats increases. To ensure the safe and reliable transfer of data, security is critical in the IoT environment. Here are a few reasons why security is essential:

Data Protection

Security ensures that data is protected during transmission, preventing unauthorized access and potential breaches.

Device Integrity

Maintains the authenticity and integrity of devices, preventing tampering and ensuring they function correctly.

Privacy

Safeguards personal information collected by IoT devices, preventing unauthorized access or exposure.

Operational Continuity

Protects IoT systems from cyberattacks, preventing disruptions and ensuring continuous operation.

Trustworthiness

Enhances user confidence by ensuring that IoT devices are secure and resilient against potential threats.

Regulatory Compliance

Helps organizations meet legal and industry standards, avoid penalties, and ensure adherence to guidelines.

Unauthorized Access Prevention

Prevents unauthorized individuals from controlling or exploiting IoT devices, protecting against malicious activities.

Secured Communication

Secured Device Communication

  • An option to enable high-level encrypted MQTT message/data transfer by connecting devices securely with SSL/TLS
  • Supports the use of any self-signed client certificates created using any server certificate authority like OpenSSL, Premium CA, or Let’s Encrypt.
  • Get your devices connected to be authenticated with an X.509 certificate to safeguard against malicious impersonators
  • Payload encryption to prevent attackers from decrypting the data if they get access to the MQTT protocol packet.
MQTT Authentication

MQTT Authentication

  • MQTT Broker / MQTT servers authenticate & verify the requested connection of the client with SSL / username and password.
  • Use a common auth key & token for all device connections or for a specific group of devices.
  • Assign an individual auth key & token which requires each IoT device to verify their identity (Client ID) independently.
  • Restrict unknown entries & allow only qualified MQTT clients to access specific resources by assigning the list of permissions READ ONLY, WRITE ONLY & READ/WRITE with ACL & RBAC authorizations.
  • Create or Delete the Auth Tokens as needed.
    • Explore More
Application level security

Application level security

  • The next level of protection for both communication & data storage is by verifying device access with any of the firewalls.
  • The data carried over the protocol will be secured at each level of the networking model as this message protocol is working on top of the TCP/IP providing information security such as confidentiality & integrity.
  • Built-over a strong back-end framework to be secure against all phishing attacks.
Access Control List

Controlling & Securing Topic Access

  • The built-in Access Control List (ACL) restricts topic access to authorized users, ensuring secure and controlled communication within the network.
  • Provides detailed control over who can publish or subscribe to specific topics, enabling precise management of messaging permissions.
  • Limits unauthorized modifications, safeguarding the integrity and reliability of data exchanged.
  • Optimizes resource allocation by controlling client access, ensuring broker resources are used efficiently by authorized users.

Enhanced Password Protection

  • By encrypting passwords at creation and not storing them in plaintext, we ensure that sensitive credentials are protected from unauthorized access, providing peace of mind that your data is secure.
  • With passwords not stored in the database, the potential risk of data exposure from a database breach is greatly reduced. This measure helps to safeguard your information from possible cyber threats.
  • User account passwords are encrypted upon creation, ensuring they remain safeguarded and confidential, protecting sensitive credentials from unauthorized access.
