Description: The security strategy for devices in the Internet of Things (IoT), including microcomputers like Raspberry Pi, refers to a set of measures and practices designed to protect these devices from unauthorized access and cyber threats. Since these devices are used in a variety of applications, from educational projects to home automation, it is crucial to implement a robust security strategy. This includes setting strong passwords, regularly updating the operating system and software, as well as implementing firewalls and other security tools. Additionally, it is recommended to disable unnecessary services and use secure connections, such as SSH or VPNs, to access the device. The security strategy not only protects the integrity of the system but also safeguards stored data and user privacy. In a world where cyber threats are becoming increasingly sophisticated, having a well-defined security strategy is essential for any user, whether a hobbyist or a professional.
