ANSI X.9 (or “ANSI/X.9”) is a group of standards commonly used with bulk data transmissions in item processing and Fed transfers. An example of an ANSI X.9 standard is “ANSI X9.100-182-2011” which covers how XML can be used to deliver bulk data and images. Published ANSI standards may include some technical artifacts such as XML[..]

AS2

AS2 (“Applicability Statement 2”) is an SMIME-based transfer protocol that uses HTTP/S to transmit files with end-to-end encryption and guaranteed delivery/non-repudiation (when MDNs are in use). There are two main reasons that AS2-based transmission systems are unpopular unless specifically requested by particular partners are complexity and cost. In terms of complexity, AS2 configurations can involve[..]

AS2 Optional Profiles

AS2 optional profiles (also “optional AS2 profiles”) are features built into the AS2 protocol but not used by every Drummond certified vendor.  However, the Drummond Group does validate seven different optional profiles (nine total) and these are briefly covered below. Certificate Exchange Messaging (CEM) – A standard way of exchanging certificates and information about how[..]

B2B

B2B (“business to business”) is a market definition (a “space”) that covers technology and services that allow file and other transmissions to be performed between businesses (i.e., not between consumers).  B2B covers a lot of conceptual ground, from simple “file transfer” and “secure file transfer” to more sophisticated “managed file transfer” and up through traditional[..]

BIC

A Bank Identifier Code (BIC) is an 8 or 11 character ISO code used in SWIFT transactions to identify a particular financial institution.   (BICs are also called “SWIFT addresses” or “SWIFT codes”.)  The format of the BIC is determined by ISO 9362, which now provides for unique identification codes for both financial and non-financial organisations.[..]

Certification (Software and Systems)

Certification of software and systems against a standard is better than having software and systems merely in “compliance” with a standard.  Certification 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.  Certifying agencies will usually[..]

Certification (Training)

Individuals working in the file transfer industry frequently have earned one or more certifications through training and testing.  These certifications generally fall into one of three categories: File Transfer Security Certification: (ISC)2 and SANS certified individuals have a good understanding of security from a vendor-neutral point of view.  (CISSP is an (ISC2)2 certification; CCSK is[..]

Check 21

“Check 21” is the common name for the United States’ Check Clearing for the 21st Century Act, a federal law enacted in 2003 that enabled banks to phase out paper check handling by allowing electronic check images (especially TIFF-formatted files) to serve all the same legal roles as original paper checks. Check 21’s effect on[..]

Compliance

“Compliance” to a standard is weaker than “validation” or “certification” against a standard.  Compliance indicates that a vendor recognizes a particular standard and has chosen to make design decisions that encompass most, if not all, of the standard. When a vendor has implemented all of the required standard, that vendor will frequently upgrade their statement[..]

CRC

CRC (“cyclic redundancy check”) is an early data integrity check standard (a.k.a. “hash”).  Most CRC codes are 32-bit numbers and are usually represented in hexadecimal format (e.g., “567890AB”). CRC was commonly used with modem-based data transfer systems because it was cheap to calculate and fast on early computers.   Its use carried over into FTP software[..]

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-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.
