Cyberattacks are increasingly affecting embedded systems, whose design and long lifecycles entail special security requirements. Regulatory authorities worldwide are responding to the growing threat situation with regulations such as the upcoming Radio Equipment Initiative (RED) or the Cyber Resilience Act from 2027. With the Security Upgrade Kit, Swissbit offers a user-friendly and secure solution that enables both the protection of embedded systems and compliance with relevant cyber security regulations. The kit includes an industrial-grade microSD card as well as appropriate documentation, software and tools. It offers hardware-based access control, real-time data encryption with AES 256 and allows the customization of protection profiles. Areas of application include the copy protection of sensitive data or the protection of system integrity through Secure Boot. As a retrofit solution on a microSD basis, the Security Upgrade Kit offers maximum flexibility.
Embedded systems have specific security vulnerabilities due to their long service life, difficult updating options and limited hardware capacities. They are usually designed without special protection requirements and are susceptible to attacks with physical access, which is usually only prevented by a housing or control cabinet. Once these measures have been overcome, local attackers are able to spy out sensitive information, configurations, business secrets or personal data. By manipulating system data, one-off access can also lead to undetected intrusion (APT - Advanced Persistent Threat) and the permanent interception of network communication. This is precisely where the Security Upgrade Kit from Swissbit comes in.
At the heart of the Swissbit solution is an industrial-grade microSD card, which is ideal for retrofitting as a removable medium. Equipped with a special flash controller and advanced Swissbit firmware, the card offers security functions such as configurable access controls and data protection at partition level. The optimized firmware also makes the card ideal for applications with frequent read access and long data retention.
The Security Upgrade Kit is primarily developed for Linux-based embedded systems but can also be used for other operating systems if required. Thanks to the widespread use of embedded systems, the areas of application range from industry and the public sector to critical infrastructures (KRITIS).
Swissbit provides documentation, software, tools, and a reference implementation for the Raspberry Pi for setting up and configuring the Security Upgrade Kit. Swissbit's team of experts is also available for customer-specific project inquiries and customized implementations.
