Protective markings are part of the mandatory Victorian Protective Data Security Standards (VPDSS) managed by the Office of the Victorian Information Commissioner (OVIC).
If you receive information from the department that has a protective marking, contact the originator to understand its handling requirements. Otherwise, continue to protect your information as usual.
You may also receive enquiries from staff on the sensitivity of your information to inform its handling requirements.
