If the CEO dispatches his data exclusively via AS2 (to respond to the casual EDI) instead of via FTP or OFTP, uses AES or DES and shares his signature based upon PGP with his business partners - then maybe the time is right to have a look at our i-effect^® lexicon.

SAN

A storage area network (SAN) is a high-speed special-purpose network (or subnetwork) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users.

Typically, a storage area network is part of the overall network of computing resources for an enterprise. A storage area network is usually clustered in close proximity to other computing resources such as IBM z990 mainframes but may also extend to remote locations for backup and archival storage, using wide area network carrier technologies such as ATM or SONET.

A storage area network can use existing communication technology such as IBM´s optical fiber ESCON or it may use the newer Fibre Channel technology. SANs support disk mirroring, backup and restore, archival and retrieval of archived data, data migration from one storage device to another, and the sharing of data among different servers in a network. SANs can incorporate subnetworks with network-attached storage (NAS) systems.

SAP AG

SAP AG is a multinational software development en consulting corporation, which provides enterprise software applications and support to businesses of all sizes globally.The company´s best known product is its SAP Enterprise Resource Planning (SAP ERP) software.

SAP ERP (software)

The SAP ERP application is an integrated enterprise resource planning (ERP) software manufactured by SAP AG that targets business software requirements of midsize and large organizations in all industries and sectors. It allows for open communication within and between all company functions.

The current version is SAP ERP 6.0 and is part of the SAP Business Suite. Its previous name was R/3.

SAS

The data-transfer technology Serial Attached SCSI (SAS) moves data to and from computer storage devices such as hard drives and tape drives. SAS depends on a point-to-point serial protocol that replaces the parallel SCSI bus technology.

SAVF

Special backup file for saving iSeries objects in so-called savefiles and restoring them on other iSeries machines.

SCS

The SNA character string (SCS) has a relatively simple structure, consisting of a 1-byte hexadecimal control code followed by the data to be printed. Multiple control codes can be inserted into SCS by printing applications in order to achieve certain types of output. The SNA character string is sent to the printer in physical blocks of 256 bytes.

SHA-1

The SHA (Secure Hash Algorithm) family is a set of related cryptographic hash functions. The most commonly used function in the family, SHA-1, is employed in a large variety of popular security applications and protocols, including TLS, SSL, PGP, SSH, S/MIME, and IPSec. SHA-1 is considered to be the successor to MD5, an earlier, widely-used hash function. Both are reportedly compromised. In some circles, it is suggested that SHA-256 or greater be used for critical technology. The SHA algorithms were designed by the National Security Agency (NSA) and published as a US government standard.

The first member of the family, published in 1993, is officially called SHA; however, it is often called SHA-0 to avoid confusion with its successors. Two years later, SHA-1, the first successor to SHA, was published. Four more variants have since been issued with increased output ranges and a slightly different design: SHA-224, SHA-256, SHA-384, and SHA-512 — sometimes collectively referred to as SHA-2.

Attacks have been found for both SHA-0 and SHA-1. No attacks have yet been reported on the SHA-2 variants, but since they are similar to SHA-1, researchers are worried, and are developing candidates for a new, better hashing standard.

SMTP

Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks. SMTP was first defined in RFC 821 (STD 10),[1] and last updated by RFC 5321 (2008)[2] which includes the extended SMTP (ESMTP) additions, and is the protocol in widespread use today. While electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client mail applications typically only use SMTP for sending messages to a mail server for relaying.

SQL

SQL (commonly expanded to Structured Query Language) is the most popular computer language used to create, modify, retrieve and manipulate data from relational database management systems. The language has evolved beyond its original purpose to support object-relational database management systems. It is an ANSI/ISO standard.

Although SQL is defined by both ANSI and ISO, there are many extensions to and variations on the version of the language defined by these standards bodies. Many of these extensions are of a proprietary nature, such as Oracle Corporation´s PL/SQL or Sybase, IBM´s SQL PL (SQL Procedural Language) and Microsoft´s Transact-SQL.

SSL

Secure Sockets Layer (SSL), and its succesor Transport Layer Security (TLS), are cryptographic protocols that provide security for communications over networks such as the Internet. TLS and SSL encrypt the segments of network connections at the Transport Layer end-to-end.

In a TCP/IP structure, the SSL or TSL is situated between the application protocols (HTTP, SMTP, FTP, etc.) and the transport layer (TCP).
