Abstract
This use case addresses the persistence of external access after the relationship that justified it has changed. KRYOS-XS evaluates each material access relationship according to current purpose, scope and consequence.
Decision problem
Coalitions depend on external collaboration, so broad removal can damage the mission. At the same time, forgotten partner and contractor access creates poorly understood exposure. The decision must preserve valid relationships while identifying access that is excessive, inactive or no longer authorized.
Evidence and Hypercube reasoning
Console considers external identity, permission scope, shared resources, recent use, project or contract status, sponsor, partner classification and data sensitivity. Hypercube compares the operational value of continued access with the security consequence of compromise or misuse.
Governed workflow
Each material relationship is presented as a governed decision. KRYOS recommends retain, restrict, review, revoke or request more information. The responsible internal owner confirms the relationship, the authorized change occurs in the source platform and the resulting state is verified in the ledger.
Evaluation design
A pilot should measure expired access removed, active partnerships preserved, public or excessive sharing corrected, owner response time, unresolved relationships and the number of changes confirmed after execution.
Boundary condition
External status alone is not evidence of risk. Decisions must rest on current authorization, purpose, scope and consequence.
Reading time 2 minutes. Every decision described here is recorded in the KRYOS Decision Ledger with its evidence, authority and verified outcome.
