IoT applications are evolving, and their use has been wider than before in the last few years. However, IoT devices are not exactly the most secure devices. In fact, security breaches are very normal for many IoT devices. While there has been tremendous advent in the IoT device sector and their security, experts in the field are still searching for areas to improve further. IoT devices have evolved in use and are diverse today. However, IoT security has to evolve to the same level to apply IoT devices without many obstacles. IoT security needs to strengthen to make the entire IoT application sector more viable.
IoT devices are so universal today that nearly 127 new IoT devices become active every second globally. The presence of IoT devices is higher in the Western markets, where every household has more than 20 smart devices that work on IoT principles. The evolution of IoT facilitates the use of different IoT empowered devices in different fields. IoT is used in both the industrial and domestic sectors too. For such varied use, IoT applications need high-security levels for safe use in different environments. As IoT devices move towards a more connected universal network, the entire network's security is a major concern. When there are security lapses in a certain network, it not only jeopardizes one compromised device but the entire network. Moreover, the IoT networks carry a lot of data and are closely connected to people. Thus, a high-security level is a necessity for future IoT devices.
The capabilities and applications of IoT devices are evolving. On the other hand, the speed and efficiency of connectivity in the networks are also evolving with the introduction of 5G technology. Therefore, the security of IoT devices needs to evolve simultaneously to sustain the IoT sector in the future.
People have an extension of their presence in the online space. Today, IoT devices are how people interact. Therefore, cybersecurity is a very important aspect that cannot be ignored anymore. Many organizations are trying to improve IoT devices so that cybersecurity is a priority for devices. There are three main objectives that the major stakeholders of IoT and cybersecurity want to achieve. Firstly, since the IoT network will become universal in the next few years, private and public stakeholders have to work together to bring about a major change in cybersecurity. A collective response towards cybercrimes is very necessary today. This requires global cooperation and effort.
Secondly, while we know the present challenges to cybersecurity because of research, the field has to become forward-looking. The researchers need to study and understand future networks and emerging technologies to map out future challenges. Cybercrime and breaches evolve at a high rate. Therefore, the cybersecurity and IoT sector has to go way ahead in devising futuristic solutions to anticipated problems.
Thirdly, different stakeholders have to work together to build scalable solutions that target particular problems. The security protocols and practices need an upgrade to build cyber resilience. The bottom line is that the IoT cybersecurity sector has to evolve further in the next few years.
