I need to submit a port number recommendation for a custom application and would like to know if there are specific security considerations for specific ports.

You will need to avoid Well Known Ports:

And it would be best to avoid well-known Trojan ports:

As you have not stated what the custom application will be doing, the security considerations can vary greatly. Does the program need to communicate with the Internet? If so, what protocols will it be using? SSH? HTTP? FTP?

More information is needed to make a better recommendation based on the application's requirements.
