"Security measures have been taken by the MPS as a result of this report," the statement said
Always after the data breach. The only viable security is proactive security -- making your infrastructure the hardest possible nut to crack commensurate with the value/sensitivity of the information to be protected -- before it's been breached.
The big problems that prevent this are [1] the up front cost, which usually seems unnecessary because "nothing's happened yet", [2] the utter uselessness of current common practice in risk assessment, which typically causes assessment results to be meaningless, [3] a fundamental misapprehension that 'policies' automatically drive behaviours, [4] an almost complete lack of adequate training for staff at all levels, right up to the executive, who frequently get exempted from the (typically useless) so-called 'training' provided.
Until these deficiencies are fixed, there'll be no such thing as genuine infosec, so the adversary will usually win.
