Description: Firmware maintenance involves updating and managing the software that controls IoT devices to ensure security and functionality. This process is crucial as firmware acts as the bridge between hardware and software, enabling devices to perform their specific functions. As technology advances, IoT device manufacturers release firmware updates to fix security vulnerabilities, enhance performance, and add new features. Without proper firmware maintenance, devices can become obsolete or, worse, susceptible to cyberattacks. Firmware maintenance includes planning updates, implementing security patches, and monitoring device status. Additionally, it is essential for users and system administrators to be informed about available updates and follow best practices to apply these updates in a timely manner. In an environment where IoT devices are increasingly interconnected, firmware maintenance becomes an integral part of the overall security strategy, ensuring that devices not only operate correctly but are also protected against emerging threats.
