Security Model

Definition ∞ A Security Model outlines the protective measures and architectural design principles implemented to safeguard a system, network, or digital asset from unauthorized access, use, disclosure, disruption, modification, or destruction. It specifies the protocols, mechanisms, and policies that collectively ensure data integrity, confidentiality, and availability. This model addresses potential vulnerabilities and defines strategies for risk mitigation. A robust security model is fundamental for trust and operational continuity.
Context ∞ Security Models are a constant focus in news concerning cybersecurity, blockchain development, and digital asset protocols. Reports often analyze the effectiveness of various models following security breaches or audits of new platforms. The ongoing evolution of these models, particularly in decentralized environments, remains a critical area for maintaining user confidence and system resilience.
