IoT Security, Future Challenges, and Open Issues

Introduction

The Internet of Things (IoT) is a rapidly growing technology that has the potential to revolutionize many aspects of our lives. It enables us to connect physical objects and systems with each other, allowing for unprecedented levels of automation and control over everyday tasks. However, this increased connectivity also brings new security challenges which must be addressed for IoT devices to remain secure and reliable. This paper provides an overview of the current state-of-the-art in IoT security research, focusing on future challenges and open issues that need to be addressed to ensure the safe deployment of these technologies. The concept behind the Internet of Things (IoT) was first proposed by Kevin Ashton in 1999 (Akhtar, N. 2020). Since then, it has grown into one of the most important emerging technologies today due its ability to enable seamless communication between different types of connected devices such as sensors, actuators, controllers etc., thus enabling various applications ranging from smart homes and cities through industrial automation up until healthcare monitoring systems (Shafiq et al., 2022) As more and more “things” are being connected via networks like Wi-Fi or Bluetooth Low Energy (BLE), there is an increasing demand for robust security solutions that can protect them against malicious actors who might try to gain unauthorized access or disrupt their normal operation. A general representation of IoT is depicted below in Figure 1.

The Internet of Things (IoT) is a rapidly evolving technology that has become an integral part of our daily lives, allowing us to connect and interact with the physical world in ways never before possible. IoT devices are becoming more powerful, interconnected, and ubiquitous every day; however, this also raises significant security concerns surrounding these technologies. As the number and complexity of interconnected systems increase, so do the risks associated with them. For organizations to remain secure while taking advantage of the full potential of IoT-enabled solutions, it will be necessary to address some pressing challenges related to IoT security (Aqeel et al., 2022).

Another important area where improvements can be made is device authentication protocols used when connecting individual smart products together over wireless networks such as Bluetooth Low Energy (BLE) (Inayat et al., 2022). Due to the limited computing power available on many embedded systems found in everyday consumer electronics items like fitness trackers, home automation controllers etc., current authentication methods may not provide adequate protection against sophisticated attacks aimed at gaining control over those devices. For example, if two BLE enabled products were designed using weak encryption algorithms then hackers might target one product as entry point into larger network containing other sensitive personal or business assets (Ssa et al., 2023). To mitigate such threats manufacturers should consider implementing stronger cryptographic solutions during development phase coupled with regular software updates after deployment keep all users safe from cybercriminals looking exploit weaknesses these types of electronic gadgets.
