Comparison Between FTP and FTPS

FTP (File Transfer Protocol): A standard protocol for transferring files between a client and a server over the internet, but it lacks built-in security as data is transferred in plain text.

FTPS (File Transfer Protocol Secure): An enhanced version of FTP that uses SSL/TLS encryption to secure file transfers, protecting credentials and data from interception.

Comparison: FTP vs FTPS

Aspect	FTP (File Transfer Protocol)	FTPS (File Transfer Protocol Secure)
Definition	Standard protocol for transferring files over the internet.	An extension of FTP that adds support for secure file transfer via SSL/TLS encryption.
Security	No built-in encryption. data is transferred in plain text.	Encrypts the data and control channels, protecting credentials and file contents.
Encryption	Not available.	Uses SSL/TLS encryption for secure communication.
Authentication	Username and password are sent in plain text.	Credentials are encrypted and may support certificate-based authentication.
Data Integrity	Data integrity is not guaranteed.	Ensures data integrity with SSL/TLS mechanisms.
Port Usage	Typically uses ports 20 (data) and 21 (control).	Uses ports 20 and 21, but can secure these with SSL/TLS.
Firewall Configuration	Firewall setup can be straightforward but lacks secure options.	Firewall setup may be more complex due to dynamic port range for secure connections.
Compliance	Not compliant with modern security standards (e.g., HIPAA, GDPR).	Meets compliance standards requiring encrypted file transfers.
Ease of Use	Easy to configure and use.	Slightly more complex due to certificate management and secure channel configuration.
Use Case	Suitable for non-sensitive data transfers in trusted networks.	Preferred for sensitive data transfers requiring encryption and secure communication.
Protocol Variants	Basic FTP only.	Supports both explicit (STARTTLS) and implicit FTPS modes.

Key Differences

• Security: FTPS adds encryption via SSL/TLS, whereas FTP transmits data in plain text, making it susceptible to interception.
• Compliance: FTPS aligns with security and privacy regulations, while FTP does not meet modern standards for secure communication.
• Setup: FTP is simpler but less secure. FTPS requires managing SSL/TLS certificates and may involve more firewall configuration.

Summary Note

• Use FTP when transferring non-sensitive data in a secure, trusted environment where speed and simplicity are key.
• Use FTPS when handling sensitive data, ensuring compliance with security standards, or when operating in untrusted networks.
