Annex A 5.12
Classification of information
Information is classified according to its sensitivity and to legal and business requirements.
What an assessor looks for
The scheme must be simple enough that staff apply it consistently. Assessors test consistency by asking two people to classify the same document.
Where it usually fails
A five-tier scheme exists and everything in practice is filed at the middle tier, which means the scheme is decorative.
