Overview: What is a Digital Certificate?

When users come to your website, they have a way of telling whether your site is safe to connect with or not. It comes in the form of something called a digital certificate. Today, we'll help you understand what a digital certificate is, its key components, the role it plays in Web security, and other concepts associated with it.

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.

Overview

Hashes are essential to secure file transfers. You can find them in operations involving passwords, file integrity checks, digital signatures, digital certificate thumbprints or fingerprints, and others. But what are hashes? In this post, we'll introduce you to hashes, the concept of hashing, and its applications in various areas of security.

Overview: Symmetric vs. Asymmetric Encryption

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? What is the difference between symmetric and asymmetric? 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.

Overview: What is WebDAV?

Web Distributed Authoring and Versioning, or WebDAV, is a protocol whose basic functionality enables users to share, copy, move, and edit files through a web server. It can also support collaborative applications with file locking and revision tracking features. This blog post will introduce you to the basic functions of WebDAV, its similarities and differences with FTP and other file transfer protocols, and a few examples showing what you can do with it.

Overview

Here's another task many customers want to automate on their SFTP, FTPS, or FTP server. They want their server to monitor certain directories and delete old files found there as soon as the files have reached a certain age. In this tutorial, we're going to show you how to automatically delete old files from JSCAPE MFT Server using triggers. These instructions apply irrespective of the file transfer protocol you activate on the server, so if you think this is something you can use, feel free to read along.

Overview

What is TFTP? Like its more popular and more versatile cousin, FTP, TFTP or Trivial File Transfer Protocol is also a protocol for transferring files. However, it's targeted at certain tasks. In this post, you'll learn about the basic properties of TFTP, where it's commonly used, its vulnerabilities, how it differs from FTP, and other essential information about it.

Overview

A compromised file transfer server admin user account is always a huge problem. In the hands of a person with malicious intentions, a user account with administrative privileges can turn into a massive data breach. Thus, there may be cases when you'll want to be notified whenever an admin gains access to your system. If the login looks suspicious, you'll still have time to take appropriate action. In this post, I'll show you how to configure JSCAPE MFT Server so that it can automatically send an email to anyone who needs to know each time an admin logs in.

Earlier this month, the PCI SSC (Payment Card Industry Security Standards Council) published a bulletin on impending revisions to PCI DSS (Payment Card Industry Data Security Standard) and PA DSS (Payment Application Data Security Standard). The bulletin focused on SSL's failure to meet PCI SSC's definition of "strong cryptography" and the move to revise the two standards in light of this development.

Some of the most common download-related questions people ask at our help desk are probably those that have to do with filenames that have dates on them. I encountered another one yesterday, so I thought it would be a good idea to write a blog post about the subject and build on it as I encounter different solutions along the way. Who knows? Some of you folks out there might find it useful. Better yet, you might be able to contribute your own expressions so that we can all benefit from them. Sounds like a plan? Let's get this ball rolling.
