Translating expectation into requirement
Regulatory texts do not draw architectures; they state expectations. The first task is converting those into measurable technical requirements: within which boundaries data stays, who may reach it, which records are kept.
- Each requirement cites the text it rests on
- Points open to interpretation go to legal for confirmation
- A requirement that cannot be met is listed rather than hidden
- Requirements are revisited as regulation changes
Choosing the isolation level
'Private cloud' is not one thing: logical isolation, dedicated hardware and a fully separate environment carry different costs and different levels of control. The choice follows which level the requirement genuinely calls for.
- Isolation level can differ per component
- A shared management plane is assessed separately
- Cost differences are shown per level
- The reasoning can be presented during an audit
Access and privilege control
In a regulated environment, who reached what matters as much as the access itself. Administrative access is granted with approval and an expiry; sessions are recorded and those records are stored beyond the reach of whoever accessed.
- Administrative access opens on request and approval
- Session records are kept where the accessing party cannot erase them
- Provider personnel access is inside the same scope
- Emergency access uses a separate account and raises a notification
Audit readiness
When an audit arrives, evidence should be presented rather than produced. Records showing that controls operate are generated continuously and reviewed on a regular cycle.
- Evidence is produced continuously, not assembled during an audit
- Control owners and a review calendar are established
- Each finding carries an owner and a closing date
- Provider reports are reconciled with your own records
