01 / DECISION
Define the operational decision
A protected master can still be lost to storage failure, ransomware, accidental overwrite outside the protected path or unavailable credentials. Recovery must not depend on the same device and access route.
Maintain a separately controlled, restorable backup and a time-limited emergency access procedure for the price master.
02 / PROCEDURE
Run the control sequence
- 01
Back up the approved master and its release record separately.
- 02
Restrict backup administration independently from daily price editing.
- 03
Test restore into an isolated location without replacing production.
- 04
Define temporary emergency access, owner and expiry.
- 05
Record the recovery point, restore result and next test date.
03 / EVIDENCE
Keep a usable release record
Record the master path, accountable owner, working-copy identifier, proposed change, reviewer, approval time, release version, cryptographic hash, backup location, restore result, temporary-access expiry and publication outcome. Keep this evidence outside the protected artifact so it remains available when the file cannot be opened.
Use a consistent release identifier across the approval, published artifact and recovery copy. Never place credentials, customer data or unnecessary commercial detail in the evidence record. Retain prior approved versions according to policy, and verify that the artifact accepted by the downstream POS matches the one that was reviewed.
04 / BOUNDARY
Keep adjacent controls separate
Access restriction is not backup, disaster recovery, malware protection or proof that a restored file is commercially current.
Test restrictions with representative roles and a nonproduction file before applying them to the only master. Preserve an independently restorable backup, keep price authorization separate from technical administration, and confirm that automated import services still have the access their documented task requires. After an update, compare the released version and hash, review the POS import result and close any temporary exception. Recheck the workflow after Windows, product, account, folder, storage or POS changes because earlier evidence may no longer describe the current environment.
05 / QUESTIONS
Common questions
Does a protected file prove its prices are approved?
No. Approval evidence, pricing logic and file restrictions solve different problems.
Can the protected master replace a backup?
No. Keep and test a separately controlled recovery copy.
Should administrators remove every restriction during an urgent update?
No. Diagnose the exact required action and grant the smallest approved, time-limited exception.
