I need advice on how to increase security for the firewall...
Right now all the ports are closed except two of them becasue the internet application needs to reach the database to update the information in the database.
If someone were to compromise the web server, they could easily get to all the databases located on the server which can be accessed from the internet in order for the code to to update the databases. I need to find a way to lock this down, and still have the application connect to the database.
Is there a way? If not, is there a way to increase security?
Is there a way to hide which ports are open from hackers?
