DBCS access rules best practices

Content

Dears,

 

Kindly find below a document from Oracle, about how to connect Java application using JDBC to Oracle DB in the cloud.

They are unblocking the port 1521, so that we access the DB from Java application.

Kindly check the below blog and appreciate your feedback if this is the right way to do this.

PFA image about creating an access rule to access the db.
What I am currently doing is exposing the port 1521 to PUBLIC INTERNET, which I dont think is the right way.

 

Kindly adivce,

Thanks in advance
