Data Classification and Secure Transfer

By the end

What you'll build

• Assign the correct classification level to a document, dataset or message and defend the choice
• Apply the handling rules that follow from each level, covering storage, access, sharing and retention
• Choose a transfer method appropriate to the classification and limit who can open it at the other end
• Minimise, redact or de-identify data before sharing it beyond the people who need it
• Find and close copies left in old shares, local drives, exports and departed colleagues' spaces
• Dispose of data and media so that recovery is not a practical concern
