Is it safe to push the development stack (framework, server, language, etc.)?

Question

I am launching a small launch and have developed several web applications. We make extensive use of open source technology, and I want to give credit to the attribute that we use.

The only thing I'm worried about is it safe to expose everything? For example, web server, development language and structure, etc. Are there any problems?

eg. One of the special problems is that if a vulnerability is detected in the infrastructure, the application can be an easy target until it receives the patch.

Answer 1

The more a person knows, the more leverage you can use. He said that this should not be a big problem if you are building your web application with security in mind.

Answer 2

There should be no problem - many companies publish information that they use specific open source solutions.

The main weaknesses are the obvious security-related ones: have you changed all the administrator passwords by default, etc.?
