Description: Security techniques refer to the methods used to protect embedded systems from unauthorized access or attacks. These systems, designed to operate in specific devices and controlled environments, require a robust security approach due to their critical nature and often network-connected status. Security techniques encompass a variety of strategies, including user authentication, data encryption, firewall implementation, and software update management. Authentication ensures that only authorized users can access the system, while encryption protects sensitive information from being intercepted. Firewalls act as barriers between the system and potential external threats, filtering unwanted traffic. Additionally, update management is crucial for keeping the system protected against known vulnerabilities. In a world where devices are increasingly interconnected, security techniques in embedded systems become essential to ensure the integrity, confidentiality, and availability of the data and services these systems provide. The effective implementation of these techniques not only protects the hardware and software but also ensures user trust and the operational continuity of critical applications that rely on these systems.
