Choosing Between SSL Implicit, Explicit, and Forced Explicit Modes

Posted by John Carl Villanueva on Sun, Nov 04, 2018 @ 09:07 PM

Overview

There will be times when you'll want to transfer files over a secure connection. One option is to use FTPS (FTP over SSL) which provides data-in-motion encryption through SSL (Secure Sockets Layer). When you setup an FTPS service in JSCAPE MFT Server, you'll notice that you actually have 3 modes to choose from explicit SSL, forced explicit SSL and implicit SSL.

An Introduction To Cipher Suites

Posted by John Carl Villanueva on Wed, May 16, 2018 @ 11:26 PM

The security of any SSL/TLS-protected connection largely depends on the client and server's choice of cipher suites. If you use file transfer protocols like HTTPS, FTPS, and AS2 but don't know what cipher suites are, you will want to read this post.

Should We Start Using 4096 bit RSA keys?

Posted by John Carl Villanueva on Fri, Nov 24, 2017 @ 12:32 AM

Theoretically, RSA keys that are 2048 bits long should be good until 2030. If so, isn't it a bit early to start using the 4096-bit keys that have become increasingly available in encryption-enabled applications? It depends.

Excluding Passive IP for Internal FTP/S Connections To Your Reverse Proxy

Posted by John Carl Villanueva on Sun, Nov 27, 2016 @ 09:58 PM

Overview

Last time, we tackled the problem system administrators encounter when their passive FTP or FTPS connections have to pass through a NAT firewall or router. A similar problem can happen when you're dealing with the same type of connections and a reverse proxy. It gets even more complicated when you have to deal with both external and internal users. Let me show you how to deal with that.

Setting Up An FTPS Server Behind A Firewall or NAT For PASV Mode Data Transfers

Posted by John Carl Villanueva on Sat, Nov 05, 2016 @ 03:43 PM

It’s never easy to set up an FTP server the moment firewalls get involved. But it gets even more difficult once you start using the secure version of FTP, known as FTPS. In this post, we’ll talk about the problem you’ll usually encounter when your FTPS server is behind a firewall and your client is attempting to perform a file transfer using passive mode or PASV.

What Is HMAC And How Does It Secure File Transfers?

Posted by John Carl Villanueva on Wed, Aug 31, 2016 @ 02:10 AM

Overview

Data integrity checks are vital to secure communications. They enable communicating parties to verify the integrity and authenticity of the messages they receive. In secure file transfer protocols like FTPS, SFTP, and HTTPS, data integrity/message authentication is usually achieved through a mechanism known as HMAC. In this post, we explain what HMAC is, its basic inner workings, and how it secures data transfers.

What Is The Best FTP Alternative For Business?

Posted by John Carl Villanueva on Fri, Aug 12, 2016 @ 11:30 AM

Overview

In our last post, we talked about the importance of applying the CIA Triad to enterprise file transfers. Interestingly, one of the most widely used file transfer protocols, FTP, fails to meet the security goals of that triad. If you're using FTP in your business operations, it's high time to find an alternative. This post introduces you to some of the top options.

SHA2 Certificates Are Imperative

Posted by John Carl Villanueva on Sun, May 15, 2016 @ 06:04 PM

Overview

Over the last few months, we've been receiving a growing number of inquiries on how to enable support for SHA2 certificates in JSCAPE MFT Server. We later learned that the intention was not just to accommodate SHA2-signed certs but to actually replace SHA1-signed certs with them. In this post, we explain why people are moving from SHA1 to SHA2 and why you need to do so as well.
