Access, data and communication can be secured using Swissbit security products which ensure machines from cyber-attacks. SD and microSD memory cards have special firmware extensions and variants with an integrated smart card chip. The SD memory cards with secure elements allow developers to introduce a root of trust or to perform security updates easily. Thanks to the APIs included, implementing security routines is simple as well. The combination of a standard industrial data medium with security features allows for easily upgradeable solutions. Consequently, security solution updates can be implemented at any time.
