What type of control is suggested when IoT devices become unsupported due to the manufacturer going out of business?

When IoT devices become unsupported due to the manufacturer going out of business, a compensating control is often suggested to mitigate the risks associated with using those unsupported devices. Compensating controls are alternative measures that are put in place to achieve a similar level of protection when the primary control is no longer effective or available.

In the case of unsupported IoT devices, these compensating controls may include implementing network segmentation to isolate the unsupported devices from critical systems, deploying firewalls to restrict their access, or employing monitoring tools to keep an eye on their behavior and detect potential vulnerabilities or breaches. The goal is to maintain security despite the lack of manufacturer support and the associated risks, such as exposure to vulnerabilities that may no longer be patched.

The other types of controls mentioned involve different approaches. Technical controls are security measures implemented through technology, such as firewalls or anti-virus software, but they would not directly address the issue of unsupported devices. Administrative controls refer to policies and procedures designed to manage security, such as training and awareness programs, but they may not provide the immediate technical protections needed in this scenario. Preventive controls aim to stop security incidents before they occur, but may not be applicable once a device is already unsupported and poses a risk.

Thus, in the
