After being deployed, Internet of Things devices may need further updates or timely fixes. It will sometimes need to be fixed or replaced, which may result in some downtime. The issue may be fixed by using IoT Device management, which can maintain the devices so that they are in excellent working order.   Provisioning, authenticating, configuring, monitoring, provisioning, and maintenance of linked devices and software are all part of IoT device management. When it comes to guaranteeing the safety of Internet of Things devices as well as their connection, efficient device management is very necessary. To be able to manage devices connected to the internet of things, you will need to satisfy the following four criteria.  Provisioning and Authentication: Internet of Things devices are vulnerable to attack since their networks may be accessed over the Internet. Authentication and Provisioning. The provisioning and authentication of the devices is what has to be done in order to fix this issue.  Through the process of provisioning, you change the settings of the device from their factory defaults to those that are compatible with your network in order for it to function properly. Authentication guarantees that only authorised devices are registered in a system, hence minimising the risk of invasions and pinvasions, confidential information.  Configuration and Control: Before you can start utilising a new piece of hardware, you must first setup it. This step is always required. After the deployment has been completed, it is very important to govern and configure the devices in order to guarantee certain elements, like operation, performance, and security. This will make the process of implementing control capabilities much simpler.  Monitoring and Diagnostics: If there are software problems or certain other difficulties, the device may become inoperable for a period. Users are needed to do continual monitoring of their equipment in order to diagnose these difficulties. Management of devices provides assistance in identifying these difficulties so that they may be resolved in a timely and effective manner.  Maintenance and Updates: After being installed, a piece of hardware has to have its operating system updated in order for it to perform without flaws. This can require the addition of brand-new functions. It is essential to have the capacity to safely maintain and update the software on distant devices in order to have effective device management.
