Port 3443 is commonly used for secure communication and remote management in web servers. It is often used by web servers running Apache Tomcat, an open-source software for Java web application deployment. When HTTPS (HTTP over SSL/TLS) is enabled, communication between the web server and the client happens over port 3443. It can also be used for remote management of servers using tools like Remote Desktop Protocol (RDP) and Virtual Network Computing (VNC).
