IoT connects devices across the internet. As more and more devices and systems are embedded with network connectivity, the IoT network is keeping on growing. By expanding network connectivity to all corners of our life, we can save time and money and improve the efficiency of our lives.
A deeper analysis of the IoT network reveals various cyber threats that could be detrimental to the users and the devices. Expanded internet connectivity exposes various entry points to bad actors that can take advantage of the loopholes and perform malicious acts.
Cybersecurity Threats In The IoT System
It was in 2016 that the first wave of IoT cyber threats began when the Mirai Botnet compromised the security of many IoT devices, which include routers and IP cameras. The compromised security turned the devices into centrally controlled botnets that affected the internet connection of a million users worldwide.
Companies around the world are adopting various IoT solutions targeting better visibility and improved efficiency. Meanwhile, attackers are on the constant lookout for newer ways to gain unauthorized access to systems and data stores and compromise them. Starting from navigation systems in vehicles to IoT enabled medical devices, hackers can literally target anything.
Securing IoT Systems
Securing IoT systems is a challenging task for many reasons. Manufacturers and innovators are undergoing immense pressure to introduce newer devices that suffice the latest market needs. In the process, security is often given low priority. Moreover, many businesses are even unaware of the vulnerabilities in the IoT network because they give more attention to the convenience and cost-saving benefits of IoT.
Gartner predicts that over 25% of the enterprise attacks by 2020 will involve IoT systems. The risk is significantly high for Industrial IoT systems.
Securing the devices themselves is one way to approach the problem. For example, some equipment may not require constant monitoring during their operation but they still need to be secured. By applying tamper-proof precautions, these endpoints can be secured to prevent intruders from tapping into the devices and accessing critical data.
It isn’t just the IoT devices that should be secured. Organizations need to put in the effort to secure their IoT networks. By deploying strong user identification and access control mechanisms, it can be ensured that only authorized users are gaining access to the system.
It is not really possible to prevent the occurrence of IoT attacks altogether but organizations can still implement solutions that can effectively mitigate the cybersecurity threats.
