IoT systems specialists – Why someone needs to regulate and maintain tech communication

Introduction

A few decades ago, the idea that you could turn your lights on and off with a verbal command, or turn on your washing machine before you even arrive home, was something that sounded like it was straight out of science fiction. As Internet of Things (IoT) technology becomes increasingly integrated into homes, workplaces, healthcare facilities and public infrastructure, the importance of IoT systems specialists continues to grow. Connecting physical devices to the internet can improve efficiency, automate routine processes and provide valuable real-time information; however, it can also create significant technical, security and privacy risks. IoT systems specialists ensure that these devices communicate reliably, process information correctly and remain protected against unauthorised access. Their expertise is therefore essential not only for developing innovative connected systems, but also for preventing malfunctions, data breaches and unexpected incidents that may turn supposedly “smart” technology into a serious liability.

What is IoT, and who are IoT systems specialists?

Strictly speaking, not every electronic or connected system is IoT. It normally qualifies when a physical object uses sensors or controls, exchanges data over a network and performs or enables some form of monitoring or action. Meanwhile, IoT systems specialists are those people responsible for building and maintaining these systems. These days, it’s almost impossible to go through your day without interacting with some sort of IoT system. They can be found at home, through devices like smart televisions, robot vacuum cleaners or security cameras; in shops, with connected stock sensors and temperature sensors being great examples; and even at one’s workplace or on public transport.

A brief history

Necessity truly is the mother of invention. This has been proven time and time again throughout history, and for the creation of IoT systems, this was no different. In 1982, computer science students and staff at Carnegie Mellon University had one simple issue: unnecessary trips to the soda machine. People were tired of walking all the way to the machine just to discover that it was empty, or that it had just been refilled and the drinks were still warm. As such, they installed small switches inside the machine to monitor the bottle columns. These switches were connected to the department’s computer network, and through ARPANET (a predecessor of the modern internet), students and staff could check the machine without taking the trip down beforehand. This device is widely recognised as the first IoT device to be created, and it paved the way for modern connected devices.

Work related to IoT developed as connected technology evolved; however, these workers were normally called embedded-systems engineers, network engineers, telecommunications specialists or software developers, rather than IoT specialists. The expression “Internet of Things” was coined by Kevin Ashton in 1999 while discussing how RFID technology could connect physical objects to digital information systems.

Why are IoT systems specialists so important nowadays?

Hackers with malicious intent will try to find any possible weak point in a security system to access the information they want. As such, data security is of the utmost importance for any business, company or individual. IoT systems may pose a potential vulnerability, as one insecure device may jeopardise an entire data system. In a real-life scenario, a casino reportedly installed a connected fish tank that automatically monitored its temperature, salinity and feeding schedule. Attackers used the aquarium system as a route into the casino’s network, and data was transferred out through the compromised device. The breach was detected, but approximately 10 GB of data had reportedly already been transferred out. In a more recent example, a nationwide cyber attack made headlines on the 12^th of October when around 400 supermarkets reported that hackers had managed to hack into the software responsible for regulating temperatures within their fridges and freezers. The cyber criminals adjusted the temperatures to 50 °C, causing the food to spoil.

What it takes to become an IoT systems specialist

There is no single compulsory “IoT degree”. People often enter the profession from educational backgrounds which may include computer science, information technology, computer or electrical engineering, electronics, telecommunications or cybersecurity. For this position, you also need programming and networking knowledge and practical hands-on experience with data systems. Though often overlooked, personal skills also play a part in this career. Amongst these are analytical and problem-solving abilities, patience when diagnosing complex faults, communication and teamwork.

Conclusion

IoT systems specialists play an important role in ensuring that these devices work reliably and securely, allowing us to enjoy their convenience without overlooking the risks they may bring. It’s evident that for our devices to be truly secure, every digital pathway needs to be maintained and regulated. IoT systems specialists do just that and are dedicated to keeping everything up to date to ensure efficiency and productivity.
