Recommendation: Databases should not be directly accessible over, or connected to the internet. Protect these services with authentication, do not allow guest or anonymous login. For web applications that are accessing database data, make sure all user-supplied data is sanitized to prevent SQL injections. Actors can use this information to coerce more personal data from the victim. Users should also monitor their credit in order to make sure that nothing out of the ordinary is happening and no identity fraud is being committed.
