A.1.4.7 Temporary files

The organization must make sure that temporary files produced while processing personal data are wiped or destroyed within a documented time limit, under documented procedures, and must check regularly that temporary files no longer in use have been removed within that limit. It should recognise that such files include rollback journals and files generated by database updates and by applications running; that they serve no purpose once the task that created them is finished, though some cannot be removed straight away; and that their lifespan is not always predictable, so a clean-up procedure should find them and establish how long ago each was last used.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

  • Inventory of temporary artefacts including rollback journals, caches, spool files and interim exports · Policy repository / GRC workspace

  • Automated or scheduled cleanup with execution evidence · Document repository

  • Documented procedure naming the temporary file locations and the retention period for each · Policy repository / GRC workspace
  • Periodic verification that unused temporary files were in fact removed · Document repository

First move

Start with the 1 of 4 artefacts that already live in a system (Policy repository / GRC workspace); keep the periodic reviews but log each one as a dated record with a named reviewer.
