What evidence does an auditor ask for when you delete PII?

An auditor asks for five things: a register that names each cluster and its rule, a period specification with a start event, a completion record for the last deletion run, a route for individual requests, and a certificate or instruction for each processor. The policy alone is not evidence.

The register and the rule

The first question is what the organisation holds and why. A cluster register with a purpose, an owner, the data objects and the rule answers it. The register has to be readable by a business owner, not only by a data engineer, because the purpose is a business decision.

The period specification

The second question is when the record should have gone. A period without a start event cannot answer it. The specification needs the period, the event that starts it, the event that stops it and the evidence that the clock was read correctly. A legal hold needs an end date and a reviewer.

The completion record

The third question is what happened on the last run. A completion record with a date, an operator, the cluster and the count of objects is the minimum. A log of deletion that itself contains the identifiers needs its own rule, or the evidence becomes a new retention problem.

The individual request

The fourth question is what happens when one person asks for deletion or for a suspension. The DIS introduction adds individual requests and clause 9.8 owns the route. A ticket, a decision, an outcome and a check across every cluster is the evidence.

The processor

The fifth question is what the suppliers did. A processor instruction and a completion certificate per processor is the usual evidence. If a processor cannot provide one, that is a finding, not a gap in the draft.
