Description: IoT security refers to the practice of securing connected devices and networks in the IoT. This involves protecting both the hardware and software of devices, as well as the networks that interconnect them, to prevent unauthorized access, cyberattacks, and data manipulation. As more devices connect to the Internet, from appliances to security systems and vehicles, the attack surface expands, making security a critical concern. IoT security encompasses various strategies, including user authentication, data encryption, regular software updates, and the implementation of firewalls. Additionally, it focuses on data privacy, ensuring that sensitive information collected by devices is not exposed or misused. The growing interconnection of devices in home, industrial, and urban environments makes IoT security relevant not only for manufacturers but also for consumers, who must be aware of the risks associated with using connected technology. In summary, IoT security is an essential component to ensure trust and functionality in an increasingly digitalized and connected ecosystem.
