Data states

 1.Data at Rest (DAR)

    +Encryption,Redundancy

 2.Data in motion (DIM)

    +Separation/Isolation,Transport Security,VLANs.

    +SSL/TLS create ad encrypted tunnel.

    +IPSec tunnel mode is also a good solution.

 3.Data in Use (DIU)

    +Protection of APIs,digital signatures and encryption,restricted access.

    +Homomorphic encryption.The idea is that if we could keep a datasets encrypted while being manipulated in memory or shared with another application,we would then never have to decrypt it,making the data transaction safer.
