Data retention: no Level 1 requirement. Level 2 (a to e): retention according to legal, regulatory and business requirements; backups under the retention policy; secure deletion when data is no longer needed; periodic manual or automatic identification and deletion of data past its retention; and log retention long enough to serve as digital evidence required by regulators. Level 3 (a and b) adds a mechanism for customers to remove or destroy all their data, backups included, at contract end whether on expiry or early, and retention periods that meet regulators' requirements.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
