RFI stands for “Request for Information” and is used to ask which products and services are available to meet your file transfer needs and to get information about the firms behind the offerings.   The utility of RFIs in the acquisition of technology declined significantly with the rise of the world wide web, as much of[..]

RFP

RFP stands for “Request For Proposal” and allows multiple vendors to suggest a specific solution to your specific challenges in a well-documented and repeatable format. Good responses to a file transfer RFP will answer your questions about: Vendors’ ability to execute (e.g., experience, expertise) Vendors’ position in the industry (e.g., innovator, total solution, value-priced) Products’[..]

Right to Erasure

Under GDPR, the data subject has the right to request erasure of personal data.

Sarbanes Oxley (SOX)

The Sarbanes Oxley Act is a US federal law, enacted on 30th July 2002, governing financial reporting and accountability processes within public companies. The legislation was brought into force as a safeguard, following a succession of corporate accounting scandals, involving a number of high profile organisations. These companies purposefully manipulated financial statements, costing investors billions[..]

Secure File Transfer

Security is of paramount importance in today’s corporate environments, due to the sensitive nature of the information that they hold. Industry standards such as PCI DSS, Sarbanes Oxley and HIPAA dictate an organisation’s responsibility to secure such information and as such, the need for secure file transfer solutions has become a priority. A number of[..]

Self-Provisioning

Self-provisioning is the ability for individual end users and partners to set up (or “provision“) their own accounts. Self-provisioning is a common element of most cloud services but remains relatively rare in file transfer applications.  A major difference between those environments is that self-provisioning in cloud services usually involves linking a credit card or other[..]

SEPA

The Single Euro Payments Area (SEPA) is an EU initiative to unify payments within the EU.  It is primarily driven by the European Payments Council.  (SEPA is not, by itself, a standard.)

Service Level Agreement

A file transfer service level agreement (SLA) establishes exactly what a particular customer should expect from a particular file transfer provider, and how that customer should seek relief for grievances. A file transfer SLA will often contain the following kinds of service expectations: Availability: This expresses how often the file transfer service is expected to[..]

SFTP File Transfer

SFTP file transfer or the ‘SSH file transfer protocol’ as it is more formally known, is a network communications protocol used for sending data securely over a network. A common misconception associated with SFTP is that it uses FTP run over SSH – this is not the case. SFTP, sometimes referred to as ‘secure file[..]

SHA-1

SHA-1 (“Secure Hash Algorithm #1”, also “SHA1”) is the second most common data integrity check standard (a.k.a. “hash”) used throughout the world today.  SHA-1 codes are 160-bit numbers and are usually represented in hexadecimal format (e.g., “de9f2c7f d25e1b3a fad3e85a 0bd17d9b 100db4b3”). SHA-1 is the least secure hash algorithm NIST currently supports in its FIPS validated[..]

SHA-2

SHA-2 (“Secure Hash Algorithm #2”) is the most secure hash algorithm NIST currently supports in its FIPS validated cryptography implementations.  SHA-2 is really a collection of four hashes (SHA-224, SHA-256, SHA-384 and SHA-512), all of which are stronger than SHA-1. Complete SHA-2 implementations in file transfer are still uncommon but becoming more common as time[..]

SHA-224

SHA-224 is the 224-bit component of the “SHA-2” data integrity check standard (a.k.a. “hash”).  It is not a unique hash algorithm within the SHA-2 standard but is instead a truncated version of SHA-256. See “SHA-2” for more information.

SHA-256

SHA-256 is the 256-bit component of the “SHA-2” data integrity check standard (a.k.a. “hash”).  Like SHA-512, it is one of two unique algorithms that make up a SHA-2 hash, but SHA-256 is optimized for 32-bit calculations rather than 64-bit calculations. See “SHA-2” for more information.

SHA-3

SHA-3 refers to the new hash algorithm NIST will choose to someday replace SHA-2.   A contest to select the new hash is scheduled to conclude in 2012.

SHA-384

SHA-384 is the 384-bit component of the “SHA-2” data integrity check standard (a.k.a. “hash”).  It is not a unique hash algorithm within the SHA-2 standard but is instead a truncated version of SHA-512. See “SHA-2” for more information.

SHA-512

SHA-512 is the 512-bit component of the “SHA-2” data integrity check standard (a.k.a. “hash”).  Like SHA-256, it is one of two unique algorithms that make up a SHA-2 hash, but SHA-512 is optimized for 64-bit calculations rather than 32-bit calculations. See “SHA-2” for more information.

SLA

SLA is an abbreviation for “Service Level Agreement“, which is a specific contract between a customer and a provider that lays out exactly what each side can expect from the other.   The minimum amount of work and minimum level of due care that a file transfer operations team is responsible for is often determined[..]

SMTP

SMTP is an email protocol used to push messages and attachments from server to server.  Many technologies have been used to secure SMTP over the years, but the best technologies available today use SSL (version 3) or TLS to secure the entire SMTP connection. SMTP typically uses TCP port 25 to move unsecured traffic and[..]

SSH File Transfer

SSH (Secure Shell) is a network protocol used to establish a secure connection between a client and server. Once a connection has been established, it acts like an encrypted tunnel down which data can be exchanged securely. SSH file transfer is used to maintain the confidentiality and integrity of data communications over insecure networks such[..]

SSL

SSL (“Secure Sockets Layer”) was the first widely-deployed technology used to secure TCP sockets.  Its use in HTTPS (HTTP over SSL) allowed the modern age of “ecommerce” to take off on the world wide web and it has also been incorporated into common file transfer protocols such as FTPS (FTP over SSL) and AS2. In[..]

Subject Access Requests (SARs)

Under GDPR, the data subject has the right to request all personal data a data controller has on them. This includes their supply chain.

SWIFT

The Society for Worldwide Interbank Financial Telecommunication (SWIFT) runs a popular system used by banks around the world to quickly exchange transactions with each other.  Most international interbank messages use this system.  Unlike clearing houses or other institutions that provide intermediate or final settlement of financial transactions, SWIFT is simply a secure transaction service.  Remote[..]

The Health Insurance Portability and Accountability Act (HIPAA)

HIPAA is the abbreviation of ‘The Health Insurance Portability and Accountability Act’. It is a US federal law governing the protection and privacy of sensitive, patient health care information. Proposed in 1996 by Congress, HIPAA was finally brought into enforcement by the Department of Health and Human Services (HHS) in 2001. The objective of HIPAA[..]

TLS

TLS (“Transport Layer Security”) is the modern version of SSL and is used to secure TCP sockets.  TLS is specified in RFC 2246 (version 1.0), RFC 4346 (version 1.1) and RFC 5246 (version 1.2).  When people talk about connections “secured with SSL”, today TLS is the technology that’s really used instead of older editions of[..]

Transformation Engine

A translation engine is software that performs the work defined in individual transformation maps. The transformation engines that power transformation maps are typically defined as “single-pass” or “multiple-pass” engines.  Single-pass engines are faster than multiple-pass engines because documents are directly translated from source formats to destination formats, but single-pass engines often require more manual setup[..]

Transformation Map

A transformation map (or just “map”) provides a standardised way to transform one document format into another through the use of pre-defined document definitions. A single transformation map typically encompasses separate source and destination document definitions, a field-by-field “mapping” from the source document to the destination, and metadata such as the name of the map,[..]

Translation Engine

In file transfer, a “translation engine” is a common name for a “transformation engine” that converts documents from one document definition to another through “transformation maps“. See “transformation engine” for more information.

Transmission Control Protocol (TCP)

TCP (Transmission Control Protocol) is one of the two core protocols used in Data Communications, the second core protocol being IP. Part of the Internet Protocol Suite (often referred to as TCP/IP), TCP is a transport layer responsible for higher-level operations. It provides reliable, ordered delivery of data packets between two locations and can also[..]

Transmission Window

A transmission window is a window of time in which certain file transfers are expected or allowed to occur. Transmission windows typically reoccur on a regular basis, such as every day, on all weekdays, on a particular day of the week, or on the first or last day of the month or quarter. Most transmission[..]

Trigger File

A “trigger file” is a common type of control file used to initiate further processing or retransmission.  Trigger files are typically created by the same application that original sends files into a file transfer system. The two most common types of trigger files are files with similar names to the files that need to be[..]

Triple DES

3DES (also “Triple DES”) is an open encryption standard that offers strong encryption at 112-bit and 168-bit strengths. 3DES is a symmetric encryption algorithm often used today to secure data in motion in both SSH and SSL/TLS.  (After asymmetric key exchange is used perform the handshake in a SSH or SSL/TLS sessions, data is actually[..]

Validation

Software, systems and processes that are “validated” against a standard are typically better than those merely in “compliance” with a standard.  Validation means that a third-party agency such as NIST or the PCI Council has reviewed and tested the claim of fidelity to a standard and found it to be true.  Validating agencies will usually[..]

VAN

VAN stands for “Value Added Network”.  A VAN is a data transfer service that uses EDI and/or file transfer protocols to connect to dozens, hundreds or even thousands of businesses.  VANs are often industry-specific; the ones that are will usually connect to almost every major supplier and consumer within that industry (e.g., auto parts). As[..]

Virtualisation

As a somewhat abstract definition, it is crucial to understand the context in which we are using the word ‘virtual’ before moving onto the definition of virtualisation. The term virtual, in this scenario is defined as “computing not physically existing as such but made by software to appear to do so”. Virtualisation as a concept[..]

Web Farm

A “web farm” is a high availability application architecture that is common to many vendors and products.  It usually involves the use of multiple web (HTTP/S) application servers, each serving the same function, and often relying on the use of round-robin session distribution from a network load balancer (NLB).    However, the term is also often[..]

Wide Area Network (WAN)

A network that spans a wide geographical area is referred to as a WAN (Wide Area Network). A WAN consists of a collection of LAN’s (Local Area Networks) connected by a router that maintains both the LAN information and the WAN information. The WAN side of the router will then connect to a communications link[..]
