Analysis
Tokyo Gas Network, a subsidiary of Tokyo Gas, said an employee lost a work computer containing around 20,000 personal records in August. Lost devices remain a large share of data incidents, and unlike hacking they are prevented by management rules rather than security products. Device encryption, keeping data off local storage, and an approval process for taking equipment out determine how bad the outcome is — a checklist worth applying to any company handling customer data.
