QNX OS for Safety

Fine-grained privilege control, 256-bit AES encrypted filesystems, ASLR, heap and stack protection, and MAC provide unparalleled security for your system.

QNX brings advanced, layered security mechanisms, built directly into the OS and kernel. With QNX you can build a system that offers the best possible security measures, thanks to such features as:

•              Granular control of system privilege levels.

•              Modern, layered approach to architecture.

•              Sandboxing .

•              Secure Boot.

•              Encrypted and Read-only filesystems.

•              Heap, Stack, and Memory Protection, including ASLR.

•              Anomaly detection.

These all result in a system with a reduced attack surface, with corresponding reductions in attack wake.

QNX’s customizable power strategy includes tickless operation, lazy timers, and selectable thermal and power profiles.

QNX brings advanced thermal and power management capabilities that are built directly into the OS and kernel, reduce the energy needed for by mobile and powered devices, through:

•              Tickless mode – skip unnecessary clock ticks when system is in an idle state

•              Tolerant timers – timers can have a tolerance for non-realtime timer requirements (e.g. UI response timers)

•              Lazy interrupts – interrupts can have acceptable latencies for non-realtime devices (e.g. keyboard interrupt events)

•              Dynamic Voltage and Frequency Scaling – DVFS for ARM Cortex SoCs
