The Equifax disaster is another lesson the airframe industry learned generations 
ago. Compartmentalization. (Battleships and spy networks learned that centuries 
ago.)

A single security error in the Equifax system led to losing ALL of their data.

Sensitive data should be compartmentalized, i.e. being spread among systems each 
with their own security. Access to one compartment does not give access to any 
other compartments.
