Question

I am using mongoDB Cluster with version 3.4 in google cloud compute engine, actually past week my database got attacked by hackers that\'s why i thought about using authorizatio

Answer 1

johnlowvale's answer is correct, but

keyFile implies security.authorization.

source: https://docs.mongodb.com/manual/reference/configuration-options/#security.keyFile

You have to disable authorization AND the keyFile.

security:
  authorization: disabled
# keyFile: /opt/mongodb/keyfile

(insufficient rep or I'd have just commented this on johnlowvale's answer)
