Abstract: The rapid expansion of IoT presents significant security challenges, as millions of devices interconnected on a network can become potential entry points for cyberattacks. The role of Information Technology (IT) in IoT cybersecurity is indispensable, as it provides the frameworks and tools necessary for securing IoT networks and devices. This paper examines the security risks associated with IoT systems, focusing on areas such as data privacy, authentication protocols, and network security. IT solutions, including encryption techniques, intrusion detection systems, and blockchain, are explored as potential safeguards for the growing number of connected devices. The research highlights the evolving nature of cybersecurity in IoT environments and the need for constant adaptation to new threats.

The increasing number of IoT devices introduces unprecedented complexity to securing interconnected systems. Each device, from smart home gadgets to industrial IoT systems, generates vast amounts of data, making it crucial to implement robust data protection strategies. Furthermore, the lack of standardized security protocols across IoT devices results in inconsistent
security measures, leaving certain devices more vulnerable to exploitation. The integration of IT tools such as machine learning and artificial intelligence can offer proactive solutions by predicting threats and responding to anomalies in real time. Moreover, blockchain’s decentralized nature holds promise for securing IoT transactions and providing tamper-proof records, especially in critical applications like healthcare and finance.
