The main way that ports 21 and 23 relate to cybersecurity is:
**If they are open, it shows that a system is poorly configured.**
Port 21 is associated with FTP (File Transfer Protocol), and port 23 is associated with Telnet. Both of these protocols are considered insecure because they transmit data in plaintext, making them vulnerable to interception and exploitation. Having these ports open can indicate that a system is not properly secured.
