Abstract
The Internet of Things (IoT) has grown to be a vital component of modern society, allowing for greater automation, simplicity, and efficiency. However, there are serious cybersecurity issues as a result of IoT technology’s explosive growth. The increasing interconnections of gadgets also makes them more vulnerable to cyberattacks, which may damage data integrity, privacy, and safety. The significance of IoT cybersecurity is covered in this paper along with the main weaknesses in IoT systems and recommended techniques for protecting IoT ecosystems. In order to provide a safer and more secure IoT infrastructure, this paper addresses issues related to IoT security and focuses on the importance of improved security mechanisms, protocols, and industry standards.
Introduction
The way that people and businesses use technology has been completely transformed by the Internet of Things. IoT encourages innovation in a few industries, including manufacturing, transportation, and healthcare, because it allows the internet to be connected to everyday objects like wearable technology, home appliances, and industrial machinery. But as IoT devices increase in number, they give hackers a larger attack surface. IoT has many advantages, but it also faces serious security risks because of the interconnection of devices and the absence of developed security procedures. Because of this, IoT systems are vulnerable to a variety of assaults, including denial-of-service (DoS) attacks, data breaches, and illegal access to private information. Thus, to protect individuals, organizations, and critical infrastructure from possible dangers, it is necessary to understand and manage IoT cybersecurity.

Methodology
This study combines a survey of the literature with a qualitative analysis of the body of research on IoT security to explore the cybersecurity issues related to the Internet of Things (IoT) and the significance of protecting IoT systems.
Literature Review
In recent years, there has been increasing awareness of the importance of protecting IoT devices. Many studies point out the main cybersecurity issues that IoT faces. Because of their essential nature and many networked devices, IoT systems frequently function with insufficient safety measures[1]. Furthermore, a lot of IoT devices are made with very little processing power, which makes it difficult for them to implement strong safety measures[2]. IoT devices are an easy target for hackers attempting to take advantage of weaknesses due to the lack of strong security protection.
The absence of proper identification and authorization procedures in IoT devices is one of the most serious risks noted in the available research. According to[3] they talk about how devices that poor authentication methods have are vulnerable to unwanted access. Hackers are more likely to hack networks and take over IoT systems as the number of devices that are connected rises. Furthermore, IoT devices have become popular targets for hackers due to their capacity to gather, keep, and transfer sensitive organizational and personal data. This offers two risks: the possibility of breaches of personal privacy and the compromise of important company information.
The wide range of devices required makes things more difficult IoT security. Depending on the manufacturer, software, and proposed usage, any IoT device may have various weaknesses. They point out that there aren’t any common standards or procedures for protecting IoT systems[4]. Standard security frameworks that depend on central management are made more challenging by the distributed structure of many IoT devices. It is challenging to implement consistent and efficient security procedures throughout the IoT ecosystem in the absence of uniform security standards.
IoT security issues have been addressed using several methods. Using blockchain technology, which can offer global and unbreakable authentication for Internet of Things
devices, is one possible strategy[5] . Using artificial intelligence (AI) and machine learning to identify and eliminate risks quickly is another possible solution[6].
Conclusion
The Internet of Things is changing the way we work and live, there are serious cybersecurity risks as well. The potential of hackers targeting IoT devices increases significantly as their number continues to rise. Classifying IoT security through the creation of more robust security protocols, the acceptance of industry standards, and the incorporation of cutting-edge technologies like blockchain and artificial intelligence is essential to reducing these threats. To build a more secure IoT environment, manufacturers, legislators, and cybersecurity specialists must also work together more. We can only guarantee that the advantages of IoT are fully realized while reducing the security threats related to this quickly developing technology by working together.
