Excuse me for being naive. But I'm a newbie.

We have a Windows Web Server within DMZ and a Windows Application Server and MS SQL Database Server. What ports do we open for connection between them?

For example: Someone opens the Data Driven Website on the Web Server and they should be able see the data that the website is trying to access from the Database.

Currently, I'm planning to open the following ports on the Web Server to establish the access,

80 HTTP 443 HTTPS 21 FTP 3389 RDP 53 DNS 1433 MS SQL Server

Please validate my assumption. I would highly appreciate your help.

Also, please provide me any articles on this topic so that I can read.
