- Design and configuration evidence showing attributes travel with the information across each exchange · Cloud console / configuration management
periodic reviewEvidence produced at each review
- Evidence the receiving system interprets and honours the transmitted attributes · Document repository
- Records of exchanges where attribute mismatch caused the transfer to be refused · Document repository
governing documentDocuments that govern the control
- The defined security and privacy attributes required to accompany information exchanged between systems and components · Policy repository / GRC workspace
- Integrity protection over the attributes in transit so they cannot be altered · Document repository
First move
Mostly documents and reviews. Pull the 1 system-held artefact from your Cloud console / configuration management on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
Common gaps auditors find
- Attributes present inside each system but dropped at the interface between them
- Receiving system accepts attributes and ignores them, so transmission has no effect
- Attributes transmitted without integrity protection, so a downgrade in transit is undetectable
