IoT device security protection encompasses both physical and network security, and affects the procedures, technology and steps required to secure IoT devices and networks. Companies also fail to keep their IoT devices up-to-date because updated security updates are rarely issued by many software manufacturers. Some devices may have reached the end of existence, while others in the first place have never provided the option to upgrade.
To fix this weakness, the ability of the system to receive Over-the-Air (OTA) updates is crucial. OTA updates allow you to upgrade the most recent security patches for hardware, applications, and firmware over a wireless network, including 2G, 3G, 4G, 5G, Wi-FI, and CDMA connections. In operating systems, firmware, and applications, daily updates minimize the number of attack vectors.
If updates are required, the user cannot be alerted by certain devices that an update is available. Conversely, although other devices may install updates automatically, before the update takes effect, it could require a hardware reboot. When installing the update, this reboot leaves systems vulnerable and inaccessible. It is necessary to verify the origin and credibility of the update and only use the lawful applications of legitimate vendors.
There is a lack of integrity assurances for some available update mechanisms, rendering them vulnerable to alteration attacks. Before installing a new firmware image, the IoT system may also use machine-to-machine authentication methods to authenticate a server update.
Why IOT Security?
The security of the IoT network is only as strong as the individual security features of the edge devices on the network, i.e. the weakest connection. If one computer is compromised, all other devices on the network and the central system will be compromised. Since IoT involves the mass installation of data collection sensors, vulnerability in one of the devices can affect thousands of devices and ultimately your organization’s data. Numerous OEM manufacturers are active in the development and supply chain of IoT devices and sensors. Vendors set up computers with default login and passwords. Next batches in development are also equipped with the same default username and password.
Many OEMs involved in the development of IoT devices lack deep expertise in built-in devices, firmware, standards and protocol security. Perhaps more worrying is that, from a profit maximization perspective, it often makes little sense for IoT devices and component manufacturers to make the requisite investment to protect their edge devices. Security is therefore not a priority. Such devices are vulnerable to hackers’ encryption and interception attacks.
Software updates and security apps keep new bugs, problems and security threats under control. The participation of several companies in different development phases contributes to misalignment of rewards in the provision of software updates for IoT devices. Apart from that, most IoT devices have low processing power and limited memory, which is only enough to perform the assigned tasks. IoT device security is not sophisticated enough to have proper standards in place and to provide software updates through the Internet. Many IoT device security are too important to avoid running software updates. Even if the IoT system is sophisticated enough to handle software upgrades and can afford to shut down for updates like this.
