A. Basics of FTPS
Q1. What is FTPS?
FTPS stands for File Transfer Protocol Secure, an enhanced version of FTP that uses TLS/SSL encryption for secure file transfers over a network.
Q2. Why is FTPS important?
FTPS protects sensitive information during file transfers by encrypting the communication between client and server, preventing unauthorized access.
Q3. How is FTPS different from FTP?
FTP transmits data in plain text without protection, while FTPS encrypts the data using SSL/TLS, offering privacy and data integrity.
Q4. Who should use FTPS?
Organizations and individuals transferring confidential information—such as finance, healthcare, and legal sectors—should use FTPS for better security.

B. Technical Details
Q1. What ports does FTPS use?
Q2. What is the difference between Explicit and Implicit FTPS?
Yes. FTPS servers must have an SSL/TLS certificate, either self-signed or issued by a trusted Certificate Authority.
Q4. Can I use a self-signed certificate for FTPS?
Yes, but using a certificate from a trusted CA is recommended for better security and wider client compatibility.
Q5. What client applications support FTPS?
Common FTPS clients include:
Q6. How does FTPS handle file permissions?
File permissions are handled on the server side, where administrators set user roles, read/write access, and control over files and directories.
- Explicit FTPS: Port 21 for control, random ports for data.
- Implicit FTPS: Port 990 for secure control and data connections.
Q2. What is the difference between Explicit and Implicit FTPS?
- Explicit FTPS: Begins unsecured and upgrades to a secure connection.
- Implicit FTPS: Starts secured immediately without negotiation.
Yes. FTPS servers must have an SSL/TLS certificate, either self-signed or issued by a trusted Certificate Authority.
Q4. Can I use a self-signed certificate for FTPS?
Yes, but using a certificate from a trusted CA is recommended for better security and wider client compatibility.
Q5. What client applications support FTPS?
Common FTPS clients include:
- FileZilla
- WinSCP
- Cyberduck
- CoreFTP
- CuteFTP
Q6. How does FTPS handle file permissions?
File permissions are handled on the server side, where administrators set user roles, read/write access, and control over files and directories.
C. Security
Q1. How secure is FTPS?
FTPS is very secure when configured properly, using strong encryption standards (TLS 1.2 or 1.3) to protect data during transfers.
Q2. Can FTPS prevent data breaches?
While FTPS protects files during transfer, it must be combined with secure server and password policies to fully prevent breaches.
Q3. Does FTPS encrypt both commands and data?
Yes, FTPS encrypts both the control channel (logins, commands) and data channel (files transferred).
Q4. How often should I renew my FTPS certificate?
Certificates are typically renewed every 12 to 24 months to maintain uninterrupted secure operations.

D. Setup and Configuration
Q1. How do I set up an FTPS server?
You must:
Q2. Can I use FTPS on a shared hosting plan?
Yes, many shared hosting providers offer FTPS access. Confirm this with your hosting company before setup.
Q3. What is Passive Mode in FTPS?
Passive Mode allows clients to connect to the server on random ports for data transfer, useful for networks with firewalls or NATs.
Q4. How do I configure Passive Mode in FTPS?
Set a range of Passive ports on your server, allow them through your firewall, and configure your server settings accordingly.
You must:
- Install FTPS-supported server software (e.g., FileZilla Server, IIS).
- Configure an SSL/TLS certificate.
- Cyberduck
- Open required ports in your firewall.
- Create users and set permissions.

E. Troubleshooting and Common Issues
Q1. Why can't I connect to my FTPS server?
Common issues include:
Q2. What does "SSL/TLS handshake failed" mean?
This error means the secure connection could not be established, often due to certificate problems, protocol mismatches, or firewall restrictions.
Q3. Why is my FTPS transfer slow?
Encryption processing and improperly configured Passive Mode settings can slow down file transfers.
Q4. How do I fix certificate trust warnings?
Use a trusted CA-issued certificate, ensure hostname matches the certificate, and update your client’s trusted certificate list.
Q5. How can I verify that my FTPS connection is secure?
Check your client logs for successful TLS connection messages and review the server's SSL certificate details during connection.
Common issues include:
- Wrong server address or port
- Expired SSL/TLS certificate
- Blocked ports by firewall
- Incorrect login credentials
