The purpose of the service communication ports matrix is to allow the IT/DevOps team to know what communication ports/protocols are used. The communication ports list will help the security team to do the necessary firewall configuration adjustment or monitoring. That will also help IT/DevOps to build a networking communication baseline and be able to tell unusual ports or traffic communication. A sample communication ports matrix is listed here:
