Sentry Kernel key concepts part 1: Basics
When it comes to embedded systems, security and reliability aren’t just features—they’re requirements. That’s why we built the Sentry Kernel, a preemptive micro-kernel designed for micro-controllers, with security baked in from the ground up.
🔑 Key Highlights:
Minimal attack surface: Only critical devices (like DMA) under kernel control
Strong isolation: Partitioned user-space tasks and domains
Event-driven execution: Predictable, controlled flow with IRQ, IPC, signals, and DMA events
Handle-based access: No direct pointers—secure, opaque handles for all OS resources
Portable architecture: Clean separation into ASP, BSP, and Generic Kernel layers for easy portability and maintenance
Resilience: Built to withstand logical attacks and fault injection
