Enforcing Strong Passwords in Torizon OS
During the evaluation and development phases, it's a common practice to leave it disabled to speed up the process. But, just before production, it's strongly advised to enable and configure this feature in order to enforce security. Torizon brings the possibility to enforce strong passwords, and that feature comes disabled by default.
Secure Boot on Torizon OS
Secure Boot, for the sake of this article, is the process of booting an image that comes from a valid trusted source (authenticity check) while ensuring it has not been modified in any way (integrity check). The actual artifact used for booting - the Torizon OS image with Secure Boot support enabled - is referred to as the Secure Boot image.
