Advanced Software Safety Analysis Essentials Training by Tonex
Lead complex safety programs with confidence in this two-day deep dive into advanced software safety analysis. You’ll connect system behavior, requirements, and assurance arguments using industry-proven methods such as FTA, STPA, FMEA, and formal techniques. The course emphasizes traceability from hazards to mitigations, model-based reasoning, and automation to accelerate credible safety evidence.
Because modern safety-critical software is also security-exposed, we show how threat-informed thinking strengthens safety requirements and architectural defenses. You’ll learn where cybersecurity risks can escalate into safety hazards, and how to structure safeguards that address both failure and attack. The result is a practical toolkit for building robust, certifiable, and secure-by-design software systems.
