What is centralisation of data?Show answer
Combining data into one large central system makes it efficient: data is entered once, kept consistent and accessed by many. But centralisation concentrates risk. One breach exposes everything, one error propagates everywhere, and one operator can misuse a vast store. It also concentrates power in whoever controls the system.
What is security as the enabling control?Show answer
Many of these issues turn on security: access controls, authentication, encryption and audit logs that ensure only authorised people see and change data, and that misuse can be traced. Security is the mechanism by which privacy and control are enforced; without it, policy promises are empty.
