What the auditor wants to verify
Audit objective
Verify that clear desk and clear screen rules are defined, communicated, technically supported, observed, and enforced.
Evidence to request
| Evidence | Purpose |
|---|---|
| Clear desk and clear screen policy | Shows rules are defined |
| Classification/handling rules | Shows rules match sensitivity |
| Auto-lock configuration evidence | Shows clear screen is technically supported |
| Walkthrough/inspection records | Shows compliance is monitored |
| Printer/fax security review | Shows shared output devices are controlled |
| Training or awareness records | Shows staff understand the rules |
| Corrective action or sanction records | Shows repeated non-compliance is handled |
Strong evidence
Strong evidence test
Strong evidence combines documented rules, technical settings, observation, awareness, and enforcement.
- Rules cover papers, removable media, screens, printers, faxes, storage, and confidential waste.
- Auto-lock settings are enforced.
- Sensitive print/fax workflows are controlled.
- Walkthroughs show staff behavior matches the rules.
- Repeated non-compliance results in fair corrective action.
Weak evidence
Weak evidence warning
Weak evidence is a policy with no observed behavior or technical enforcement behind it.
- Policy exists but no inspections occur.
- Screens do not lock automatically.
- Printers contain uncollected sensitive documents.
- Staff do not know how to use secure printing.
- Visitor or cleaner exposure is not considered.
- Enforcement is inconsistent.
Sample interview questions
- What must be cleared from your desk before leaving?
- How quickly does your screen lock?
- What do you do when visitors enter while sensitive data is visible?
- How do you print sensitive documents securely?
- Where should removable media be stored?
- What happens after repeated non-compliance?
Common nonconformities
- Clear desk/clear screen policy missing or generic.
- Auto-lock settings not enforced.
- Sensitive papers left unattended.
- Printers/faxes expose output.
- No visitor or cleaner exposure process.
- No monitoring or fair enforcement.
