Welche Ports sind kritisch?
Was erhöht das Sicherheitsrisiko der Ports?
- TCP-Port 21: Dieser verbindet FTP-Server mit dem Netzwerk.
- TCP-Port 23: Der virtuelle Terminalservice Telnet war von Anfang an unsicher.
- TCP/UDP-Port 53: Während einige Netzwerk-Ports gute Einstiegspunkte für Angreifer darstellen, werden Andere als gute Fluchtwege genutzt.

What ports do I need to forward port 4444?
Since a firewall only allows port 80 and 443, you will need to forward either 80 or 443 on your router to port 4444. For this explanation, we are going to take port 5555 as the port open on the router, and port 4444 as the port listening on the attacking computer.

What is the difference between TCP and UDP port 4444?
TCP Port 4444. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 4444 in the same order in which they were sent. Guaranteed communication over port 4444 is the key difference between TCP and UDP. UDP port 4444 would not have guaranteed communication in the same way as TCP.
