Network security heavily depends on the proper configuration of secure and insecure ports. Insecure ports are those that lack encryption or authentication, making them vulnerable to cyber threats such as unauthorized access, data breaches, and malware attacks. Common insecure ports include FTP (Port 21), Telnet (Port 23), and HTTP (Port 80), which transmit data in plain text, exposing sensitive information to potential attackers. On the other hand, secure ports use encryption and authentication mechanisms to protect data transmission. Examples include HTTPS (Port 443), SSH (Port 22), and FTPS (Port 990), which ensure secure communication over networks. Organizations must implement firewalls, port filtering, and regular security audits to safeguard their infrastructure from cyber threats. By understanding the difference between insecure and secure ports, businesses can enhance their network security and prevent unauthorized access to critical systems.

SFTP (Secure File Transfer Protocol) and FTPS (File Transfer Protocol Secure) are both secure methods for transferring files, but they operate differently. SFTP, based on SSH (Secure Shell), encrypts both data and commands within a secure channel, making it highly secure and ideal for businesses prioritizing confidentiality. It uses a single port (usually port 22), simplifying firewall configurations.

On the other hand, FTPS is an extension of the traditional FTP protocol, adding TLS/SSL encryption for security. It supports both explicit (FTPES) and implicit FTPS but requires multiple ports for data and commands, making firewall management more complex.
