Description: Telematics security refers to the measures implemented to protect systems that collect and transmit data remotely, especially in the context of advanced mobile networks like 5G. This security is crucial due to the increasing reliance on connected devices and the amount of sensitive data transmitted over these networks. Telematics encompasses a wide range of applications, from fleet management and vehicle monitoring to telemedicine and the Internet of Things (IoT). Key features of telematics security include user and device authentication, data encryption in transit and at rest, as well as the implementation of firewalls and intrusion detection systems. The relevance of this security lies in the need to protect user privacy and data integrity, especially in an environment where cyber threats are becoming increasingly sophisticated. With the advent of 5G, telematics security becomes even more critical, as this technology allows for greater speed and connection capacity, which in turn increases the risk of cyberattacks. Therefore, telematics security is not only a technical component but also an essential aspect for user trust and the adoption of new technologies.
