Access to context
Define the identities and roles that need access to each source, record and model input. Test both permitted access and denied requests.
Security startswith clear boundaries.
Put access, authority and accountability at the center of an operational design.
Security should follow the decision.
Before connecting a source or enabling an action, define who can see the information, who can change it and how a decision will be reviewed.
Authority to act
Identify which changes require approval and who can authorize them. Define how actions are scoped, acknowledged, retried and stopped.
Evidence over time
Connect source information, evaluation, operator decisions and system responses. Set requirements for retention and inspection.
Access with purpose
Define who needs which information, for what task and for how long. Consider how access changes when roles or responsibilities change.
Understand the evidence
Keep the source and age of information visible when evaluating a decision. Distinguish observations from assumptions and derived conclusions.
Authority to act
Separate the ability to inspect information from authority to approve or execute a change. Define ownership and escalation before enabling an action.
