The Internet of Things (IoT) refers to a network of interconnected devices that can communicate and perform specific functions autonomously or semi-autonomously. These devices range from smart home gadgets like thermostats and cameras to industrial sensors and wearable technology. A key characteristic of many IoT devices is that they often come with insecure default settings, such as weak passwords or open ports, which can lead to vulnerabilities if not properly configured by the user.

Manufacturers frequently prioritize functionality and time-to-market over security, leading to devices that may not offer robust security measures out of the box. This can create risks, as attackers can exploit these defaults to gain unauthorized access to networks or sensitive information.

In contrast, artificial intelligence focuses on algorithms and data processing rather than the devices themselves, cloud computing involves remote servers for data storage and processing, and blockchain technology centers around secure, decentralized data transactions. Thus, they do not primarily feature the same concerns related to device security and default configurations as seen with IoT devices.
