In embedded systems, three pillars define success: ✅ Real-time performance → minimize interrupt latency, design for worst-case response ✅ Reliability → watchdogs, error handling, and safe recovery keep systems alive under stress ✅ Security → secure boot & encryption protect devices from tampering and attacks The best designs balance all three: fast, fault-tolerant, and secure. #system #security #software #computerscience #cybersecurity
