Description: Embedded security refers to security measures specifically designed for embedded systems, which are computational devices integrated into other systems to perform specific functions. These systems can be found in a wide variety of applications, from household appliances to automobiles and medical devices, requiring a particular approach to security due to their nature and often their connectivity to networks. Embedded security encompasses both the protection of the data they handle and the integrity of the system itself, ensuring they are not vulnerable to external attacks or tampering. Key features of embedded security include authentication, data encryption, malware protection, and the ability to efficiently perform security updates. Since many embedded systems operate in critical environments, such as healthcare or transportation infrastructure, implementing robust security measures is essential to prevent failures that could have serious consequences. In summary, embedded security is a vital component in the design and operation of embedded systems, ensuring their safe and reliable operation in an increasingly interconnected world.
History: Embedded security began to gain attention as embedded systems became more common in the 1990s, especially with the rise of Internet connectivity. As devices connected to networks, concerns about vulnerability to cyberattacks emerged. In 2005, the term ‘Internet of Things’ (IoT) was coined, leading to an increased need for specific security measures for embedded devices. Over time, security standards and protocols, such as the ISO/IEC 27001 standard, have been developed to address security in embedded systems.
Uses: Embedded security is used in a variety of critical applications, including medical devices, connected cars, industrial control systems, and smart appliances. In healthcare, for example, devices that monitor health require security measures to protect sensitive information and ensure safe operation. In the automotive industry, navigation systems and connected vehicle controls need protection against attacks that could compromise the safety of the driver and passengers.
Examples: An example of embedded security is the use of authentication and encryption in health monitoring devices, such as wearables that track physical activity and heart rate. Another example is the implementation of firewalls and intrusion detection systems in connected cars, which protect against unauthorized access to vehicle control systems. Additionally, industrial control systems often use security protocols to protect critical infrastructure from cyberattacks.
