Secure boot is the product control that prevents unauthorised firmware or software from running during startup. For connected products, it is one of the main ways to protect firmware integrity, support trustworthy updates, and retain evidence that the released product boots only code approved by the manufacturer.

Secure over-the-air (OTA) updates let a manufacturer deliver security fixes to deployed products without weakening firmware integrity, bricking devices, or losing evidence of what changed. For connected products, the update mechanism is part of the security architecture, not just a delivery channel.
