The US General Accountability Office published a report about federal agencies' use of Internet of things (IoT) devices and technologies. According to the survey, 56 out of 90 agencies reported using IoT technologies for the following purposes: (a) controlling or monitoring equipment or systems, (b) controlling access to devices or facilities, (c) tracking physical assets such as fleet vehicles or agency property. The agencies also use IoT devices to perform tasks such as monitoring water quality, watching borders, and controlling ships in waterway locks. In the future, many agencies plan to begin or expand the use of IoTs, while 13 agencies announce they do not plan to use IoTs at all. The agencies reported that the main benefits of using IoTs are the ability to collect data to improve operational efficiency and the main challenges in adopting IoT are cybersecurity and interoperability.
