問題文
A data protection rule must apply the same definition of sensitive content to web uploads, to email, and to files already stored in an approved cloud application. What makes that consistency achievable?
選択肢
- A copy of the rule written separately at each enforcement point, kept in step by a periodic manual comparison that is performed whenever the definition of sensitive content is revised or extended.
- A single enforcement point, placed in front of the approved cloud application itself, through which all three kinds of traffic are forced to pass.
- Encryption of all sensitive content at rest, which makes the definition unnecessary at the network layer, because nothing readable ever leaves the store in which the content is kept.
- A single data definition that is referenced by the different enforcement points, so the meaning of sensitive is maintained in one place and applied wherever it is referenced.
