Description: A Zigbee firewall is a security device specifically designed to protect networks that use the Zigbee protocol, commonly employed in Internet of Things (IoT) applications. This type of firewall acts as a barrier between the Zigbee network and potential external threats, ensuring that only authorized traffic can access connected devices. Key features of a Zigbee firewall include the ability to filter data packets, monitor traffic in real-time, and manage device connections. Additionally, it can implement security policies that restrict access to certain devices or services within the network. The relevance of these firewalls lies in the growing use of IoT devices across various environments, including homes and businesses, where information security and protection against cyberattacks are paramount. With the increasing interconnection of devices, implementing a Zigbee firewall becomes essential to ensure the integrity and confidentiality of data transmitted through these networks, providing an additional layer of defense in an increasingly complex digital environment.
