# Security by Design **Entity class:** Concept or analytic term **Domain:** Cybersecurity / Systems Engineering **Doc Type:** Architectural Principle Node **Maturity:** Established **Related:** [[Cybersecurity]], [[Mental Privacy]], [[BCI Metadata]], [[Neural Data Sovereignty]] --- ## Definition **Security by design** integrates threat modeling, least privilege, secure defaults, compartmentalization, encryption, key management, authentication, authorization, logging, update strategy, recovery, and failure handling into a system's architecture from the beginning. ## Neural-interface relevance Neural systems create unusually sensitive attack surfaces because compromise may expose clinical identity, inferred mental state, actuator control, stimulation capability, or a longitudinal cognitive record. Security must cover devices, transport, storage, models, interfaces, operators, and supply chains. ## Neurotech cluster route **Collection:** [[collections/Neurotech|Neurotech]] **Source articles:** [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] ## Relationships [[wiki/Security by Design|Security by Design]] is related to [[collections/Neurotech|Neurotech]] through [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]]. <!-- BEGIN HUMANIZED RELATIONSHIPS 2026-09-11 --> This entry's documented connections are expressed in its definition and related-work routes, with provenance retained in the source-linked material. <!-- END HUMANIZED RELATIONSHIPS 2026-09-11 --> ## Related Work in the Corpus <!-- BEGIN HUMANIZED CORPUS ROUTES 2026-09-11 --> - In [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]], ****6\.
