SYSTEM AND NETWORK SECURITY ACRONYMS AND ABBREVIATIONS

Reports on Computer Systems Technology

The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology

(NIST) promotes the U.S. economy and public welfare by providing technical leadership for the nation s

measurement and standards infrastructure. ITL develops tests, test methods, reference data, proof of

concept implementations, and technical analysis to advance the development and productive use of

information technology. ITL s responsibilities include the development of technical, physical,

administrative, and management standards and guidelines for the cost-effective security and privacy of

sensitive unclassified information in Federal computer systems. This Interagency Report discusses ITL s

research, guidance, and outreach efforts in computer security and its collaborative activities with industry,

government, and academic organizations.

SYSTEM AND NETWORK SECURITY ACRONYMS AND ABBREVIATIONS

1. Introduction

This report contains a list of selected acronyms and abbreviations for system and network security terms

with their generally accepted or preferred definitions. It is intended as a resource for federal agencies and

other users of system and network security publications.

The capitalization, spelling, and definitions of acronyms and abbreviations frequently vary among

publications. It is easy to understand why this happens. While some acronyms and abbreviations (e.g.,

WWW) have one universally recognized and understood definition within the domain of system and

network security, others (e.g., IA, MAC) have multiple valid definitions depending upon the context in

which they are used. Some acronyms bear little resemblance to their definitions, such as Modes of

Operation Validation System for the Triple DES Algorithm (TMOVS). Others use unexpected

capitalization or spelling (e.g., Electronic Business using eXtensible Markup Language [ebXML] and

Organisation for Economic Co-operation and Development [OECD]). As a result, acronyms,

abbreviations, and their definitions may be inaccurately or inconsistently defined by authors, perpetuating

errors and confusing or misleading readers.

This report is meant to help reduce these errors and confusion by providing the generally accepted or

preferred definitions of a list of frequently used acronyms and abbreviations. The list does not include all

system and network security terms, nor is it a compendium of every acronym and abbreviation found in

system and network security documents published by NIST. Readers should refer to each document s list

of acronyms and abbreviations (typically found in an appendix) for definitions applicable to that

particular document.

The following conventions have been used in the preparation of the list of acronyms and abbreviations in

this report.

Abbreviations and acronyms generally appear in all capital letters, although there are occasional

exceptions for example, meter (m) and decibels referenced to one milliwatt (dBm).

Technical terms are not capitalized unless they are proper nouns. Names of people, places, and

groups, and the titles of protocols, standards, and algorithms are considered proper nouns. For

example, certification and accreditation (C&A) is not capitalized, but Advanced Encryption Standard

(AES) is capitalized.

Collective nouns are not capitalized (e.g., wide area network [WAN]).

When two or more definitions of the same acronym or abbreviation are given, the acronym or

abbreviation is italicized and repeated for each definition. Definitions are listed alphabetically.

2. Acronym and Abbreviation List

This section consists of a list of selected system and network security acronyms and abbreviations, along
