teal = a system already holds it · olive = produced at each review
system holds itEvidence a system already holds
- Evidence of restriction on functions as well as data, including read against write against delete and export · Identity provider / directory
periodic reviewEvidence produced at each review
- Evidence of controls over dynamic access such as reporting tools and direct query access · Identity provider / directory
- Records of testing that the restriction actually holds, such as access testing results · Identity provider / directory
governing documentDocuments that govern the control
- Evidence access to information is restricted per the access control policy, sampled at the system and data level rather than only at the network level · Policy repository / GRC workspace
- Configuration of the restriction mechanisms, such as application roles, database permissions, file share permissions and cloud storage policies · Policy repository / GRC workspace
First move
Mostly documents and reviews. Pull the 1 system-held artefact from your Identity provider / directory 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
- Access controlled at the application while the underlying database or storage is broadly readable, bypassing the whole model
- Reporting and analytics platforms replicating data into an environment with weaker restriction
- Export and download functions unrestricted, so read access is effectively copy access
- Restriction configured once and never tested, so a permission drift goes unnoticed
