Data Security - a Data Management Discipline?

Posted by Nicola Askham:

Today I came across a website I'd not seen before about Data Governance, but upon reading it, it became clear that what they were in fact referring to, is what I describe as Data Security. 

That got me thinking - in my mind it is quite clear cut, although Data Security has to be aligned to Data Governance (after all the Data Owner would be a great place to start defining who should and should not have access to a certain set of data) I have never considered it to be a Data Management discipline, placing it instead firmly in the Risk Management camp. 

But that is only my humble opinion and I'm really interested to find out what others think.
