Which layer does Zigbee accommodate security?

Zigbee incorporates security measures across multiple layers, specifically the MAC (Medium Access Control), Network, and Application layers. This layered approach allows for a more robust security framework, addressing potential vulnerabilities at various stages of communication.

At the MAC layer, Zigbee implements security features such as frame integrity checks and encryption to protect the data being transmitted over the air. This ensures that even if the physical transmission is intercepted, the data itself remains confidential and cannot be easily tampered with.

The Network layer further enhances security by implementing features such as secure network joining and network key management. This helps to establish trusted connections between devices and ensures that only authorized devices can participate in the Zigbee network.

Additionally, the Application layer can include specific application-related security controls, such as user authentication and data privacy measures, which are critical for applications that handle sensitive information.

This comprehensive multi-layered security approach is essential in industrial settings, where the integrity and confidentiality of data are paramount, and helps in protecting against a variety of potential threats throughout the communication process.
