Bound interfaces and permissions
The work assignment is to operate several connectors with separate permissions and purposes. Define purpose, owner and permitted operating boundary before the first test.
The domain review baseline covers a separate scope, data path, owner and audit evidence for each service. Assumptions and missing information remain visible in the result.
Check the data flow step by step
- Record purpose, data path, owner and required access for every service needed.
- Bound scopes by service and distinguish read access from changes with external effects.
- Test each connector separately with permitted and excluded content.
- Document audit evidence and the way to disable each service and review them regularly.
Demonstrate effects and access control
A connector inventory with separate permissions and owners is supplemented by one permitted and one denied access test per service. Audit evidence can be attributed to the relevant connector.
Avoid: one super-connector with all enterprise permissions. An access bundle whose permissions or audit trails cannot be attributed to individual services prevents targeted approval and troubleshooting.
Decision matrix
| Decision point | Proceed when | Stop when |
|---|---|---|
| Access and data path | Documented: a separate scope, data path, owner and audit evidence for each service. | Scope, data or accountability remains unresolved. |
| Connection under test | A connector inventory with separate permissions and owners is supplemented by one permitted and one denied access test per service. Audit evidence can be attributed to the relevant connector. | There is only an unevaluated demo without acceptance evidence. |
| External effect | Owner, approval, fallback and next review date are defined. | Avoid: one super-connector with all enterprise permissions. An access bundle whose permissions or audit trails cannot be attributed to individual services prevents targeted approval and troubleshooting. |
