A Security Model defines the theoretical framework and operational rules that govern how information assets and system resources are protected against unauthorized access, use, disclosure, disruption, modification, or destruction. It establishes the foundational principles for implementing security controls within a computing environment, including those handling sensitive crypto data.
Mechanism
The mechanism of a security model involves the specification of access control policies, such as mandatory access control (MAC) or discretionary access control (DAC), alongside authentication protocols and cryptographic standards. It details how users, processes, and data interact securely, ensuring integrity, confidentiality, and availability through structured enforcement points.
Methodology
The strategic approach to designing a security model involves a threat analysis, risk assessment, and the selection of appropriate security architectures to address identified vulnerabilities. This methodology mandates continuous evaluation and adaptation of controls against evolving threat landscapes, ensuring the system maintains a robust defensive posture aligned with organizational risk appetite and regulatory requirements.
