IoT\u00a0Security\u00a0refers to the technologies, policies, and processes used to protect internet-connected devices, IoT networks, and connected systems from cyber threats. As organizations increasingly rely on IoT devices for automation, monitoring, and operational efficiency, securing those environments has become a critical part of modern cybersecurity.<\/span>\u00a0<\/span><\/p>

From smart sensors and industrial machinery to medical equipment and connected consumer products, the Internet of Things (IoT)<\/a> has expanded the attack surface for businesses. Without a strong IoT security strategy, organizations face risks including malware infections, ransomware, botnets, unauthorized access, and large-scale DDoS attacks.<\/span><\/p>

IoT security is the practice of protecting IoT devices, IoT systems, and the broader IoT ecosystem from cyber threats and security breaches. It includes securing hardware, firmware, communication protocols, cloud environments, and the networks that\u00a0connect\u00a0internet-connected devices.<\/span>\u00a0<\/span><\/p>

Unlike traditional IT security, IoT cybersecurity must account for millions of lightweight connected devices that often have limited computing power, outdated firmware, or weak authentication methods. Many IoT devices are deployed in industrial environments, healthcare systems, smart buildings, and manufacturing facilities, where even a small vulnerability exploit can disrupt operations.<\/span>\u00a0<\/span><\/p>
