Certora outlines a practical threat modeling approach for Soroban smart contracts using the 4 A's framework (Assets, Actors, Assumptions, Attack Vectors) and STRIDE methodology, emphasizing that early threat modeling reduces bugs and speeds audits.
Certora presents a comprehensive guide to threat modeling for DeFi protocols and Soroban smart contracts, introducing their 4 A's framework that categorizes security considerations into Assets, Actors, Assumptions, and Attack Vectors. The article explains how STRIDE methodology complements this by examining specific contract actions for spoofing, tampering, repudiation, information disclosure, denial of service, and privilege escalation risks. The Stellar Development Foundation provides STRIDE documentation and requires threat modeling for projects seeking SDF Audit Bank support. Certora emphasizes that threat modeling should be a living document created collaboratively, updated continuously, and shared with auditors to maximize security visibility with minimal overhead.
