Threat Modeling

Definition ∞ Threat modeling is a systematic process for identifying potential security risks and vulnerabilities within a system. It involves analyzing an application or network to predict where and how malicious actors might attempt to exploit weaknesses. This proactive approach helps in prioritizing security efforts and designing robust defenses before actual attacks occur. It is a critical component of secure software development and network architecture.
Context ∞ In the realm of cryptocurrency and blockchain, threat modeling is indispensable for securing smart contracts, decentralized applications, and underlying network infrastructure. Discussions frequently revolve around the unique threat landscapes presented by distributed systems, including smart contract bugs, oracle manipulation, and consensus mechanism attacks. Future advancements will likely involve more automated and AI-driven threat modeling tools, as well as enhanced methods for analyzing complex interdependencies within decentralized networks. Continuous reassessment is vital.
