Description: Group Data Protection refers to the measures implemented to safeguard information associated with a set of devices or users in the context of the Internet of Things (IoT). This concept is crucial given the growing number of connected devices that collect, process, and transmit data. IoT security faces unique challenges, as many of these devices have limited processing and storage capabilities, making it difficult to implement robust security solutions. Group Data Protection aims to establish protocols and practices that ensure that information shared among devices or users is not vulnerable to unauthorized access, cyberattacks, or data leaks. This includes the use of encryption, authentication, and access control, as well as network segmentation to limit the exposure of sensitive data. The relevance of this approach lies in the need to protect user privacy and data integrity in an environment where interconnectivity is the norm. As more devices are integrated into daily life, Group Data Protection becomes an essential component to ensure trust and security in various digital ecosystems.
