Least privilege
Every person, service and agent accesses only what is required for its role.
TSUTSUMIAI TECHSECURITY & GOVERNANCE
Intelligence without controlis automated risk.
Security, governance and accountability are not added at the end. They shape the architecture from the beginning.
PUBLIC PRINCIPLES / PROJECT-SPECIFIC CONTROLS01 / PRINCIPLES
Six principles that constrain and guide the system
Data minimization
Collect, process and retain only information with a defined purpose.
Human oversight
Critical decisions include limits, approval and human escalation.
Traceability
Relevant actions, changes, permissions and decisions leave evidence.
Fail-safe behavior
When uncertain, the system stops, reduces scope or transfers control to a person.
Responsible independence
Architectures avoid unnecessary dependence on any single model or provider.
HUMAN OVERSIGHT
AI may recommend. Accountability remains human.
Autonomy is determined by risk, reversibility and the sensitivity of the data involved.
HUMANFINAL RESPONSIBILITY
CONTROL LIFECYCLE
From purpose to evidence
Purpose
Define the problem, user and permitted behaviour.
Data and knowledge
Map origin, quality, access, retention and updates.
Evaluation
Test quality, failure modes, limits and misuse scenarios.
Operation
Monitor logs, cost, permissions, availability and incidents.
Evolution
Reassess behaviour when data, models or processes change.
EVIDENCE, NOT CLAIMS
Controls and certifications will be published only when they exist and can be verified.
This page communicates principles. It does not replace a contract, risk assessment, privacy policy or client-specific documentation.
