MongoDb 4.2 Introduces End-to-End Field Level Encryption (Fle) for DatabasesThis update will not help to protect the databases from intrusion by hackers, but will at least make the data unreadable and therefore unusable. If something affects the attitude of database owners is that they are going to get even more reckless and lax. Nevertheless, it is expected that accessing encrypted data without the keys would make database scanning and breaching much less attractive to the attackers, so this is bound to have a positive security effect.
