What Is A Cipher?

Posted by John Carl Villanueva on Sun, Apr 26, 2015 @ 10:56 PM


Overview

The strength of an encryption largely depends on two components: 1) the cipher and 2) the length of the key. We already discussed key lengths in an older post. So today, let's talk about the other component.

What is a Digital Signature?

Posted by John Carl Villanueva on Thu, Mar 26, 2015 @ 06:38 PM


Overview

Digital signatures help enforce security during data transfers. They're mainly responsible for establishing authentication, data integrity, and non-repudiation. Today, we'll be talking about the basic concepts behind digital signatures, where they're used, how they work, and why they're always an integral part of highly secure file transfers.

Symmetric vs Asymmetric Encryption

Posted by John Carl Villanueva on Sun, Mar 15, 2015 @ 02:35 AM

Overview

Secure file transfer protocols generally employ a combination of symmetric and asymmetric encryption to preserve the confidentiality of data while in transit. So why the need for two kinds of encryption? In this post, we take a closer look at the main functions of symmetric and asymmetric encryption, their strengths, their weaknesses, and why we'd prefer having both.

What Port Does SFTP Use?

Posted by Van Glass on Mon, Jan 12, 2015 @ 07:01 PM

SFTP (SSH File Transfer Protocol), not to be confused with FTPS (Secure FTP), runs on top of the SSH (Secure Shell) protocol and by default uses port 22 for communications.  An SFTP server may however be configured to listen on a different port other than the default port.  Listening on a port other than the default port is a common tactic used to reduce the number of attacks, in particular scripted brute-force password attacks.

Setting Up SFTP Public Key Authentication On The Command Line

Posted by John Carl Villanueva on Wed, Jan 07, 2015 @ 02:44 AM


Overview

SFTP provides an alternative method for client authentication. It's called SFTP public key authentication. This method allows users to login to your SFTP service without entering a password and is often employed for automated file transfers. In this post, we'll walk you through the process of setting up this kind of authentication on the command line. It's really easier to do this on a GUI-based interface but if you simply love doing things on the terminal, this post is for you.

How To Set Up An SFTP Reverse Proxy

Posted by John Carl Villanueva on Tue, Dec 16, 2014 @ 01:15 AM


Overview

An SFTP reverse proxy adds another layer of security to SFTP services. In addition to SFTP's ability to encrypt data in transit and provide 2-factor authentication, an SFTP reverse proxy brings in several other security-related benefits such as hiding user credentials and the identities of your internal servers. An SFTP reverse proxy can be easy to set up and this post will show you how.

Setting SFTP Algorithms On Your SFTP Server

Posted by John Carl Villanueva on Wed, Dec 10, 2014 @ 02:07 AM


Overview

In this post, we'll talk about the algorithms included in a typical SFTP server and explain their basic functions. We'll cover algorithms for key exchanges, ciphers, MACs, and compressions. After that, we'll dive into the JSCAPE MFT Server Manager Web GUI and show you where you can configure those SFTP algorithms there.

Having a basic understanding of these algorithms and knowing where to configure them will enable you to strengthen your SFTP server's security or troubleshoot certain client connection issues.

What Is An SFTP Key?

Posted by John Carl Villanueva on Tue, Dec 09, 2014 @ 02:20 AM


Overview

What good is an encrypted data transfer if the information it protects still falls into the wrong hands in the end? SFTP is best known for its ability to encrypt data while in transit. But while data-in-motion encryption can secure confidential information as it traverses the network, encryption can't prevent an impostor from carrying out the download himself. For that purpose, you'll want your users to authenticate with the right password and the right SFTP key.

 

 

In this post, we'll talk about the role of SFTP keys (a.k.a. private keys) in the overall security of the SFTP protocol, how it works, where to use it, and other bits of information regarding this important element of SFTP.

Using SFTP On The Command Line

Posted by John Carl Villanueva on Mon, Dec 08, 2014 @ 01:26 AM


Overview

Although GUI SFTP clients are more intuitive to use, some people still prefer to use SFTP through the command line. That's understandable. If you're already familiar with all the commands you need, a command line interface can be so much faster and powerful than any GUI-based counterpart. In this post, we're going to introduce you to the SFTP command line and show you how it can be quite a handy tool as long as you're willing to roll up your sleeves and get dirty.
