The microSD card is the primary storage medium for all data and configuration options related to the software installation. Easily removed and duplicated, a microSD card allows storage of files in encrypted format with on demand decryption upon access.
Sensitive data include the following:
- Credentials (OS and others)
- Niagara key material
- Certificates and their private key files
The system is designed to protect these data while at the same time allowing you to move a microSD card from a failed controller to a replacement controller.
