Subject: Security Information Defined

Greetings List,

I have excerpted some security terms from a Department of Energy
(DOE) site as this is about the simplest explanations of the
terms involved. Obviously, the terms are used in relation to DOE
activities. Military personnel are no longer required to have L
or Q clearances. However, at the formation of the USAF in 1947
these special access items were required for viewing nuclear
weapons data. The requirement for military personnel was dropped
in 1955 and the military developed its own program.

Some abbreviations used below for example are:

CFRD Confidential Formerly Restricted Data
FRD Formerly Restricted Data
RD Restricted Data
TS Top Secret
TSRD Top Secret Restricted Data
etc., etc., etc.

Note: National Security Information (NSI) is ordinary classified
information, but DOE uses special identification due to the
large about of nuclear data they deal with so there will be no

Note: Other agencies designate "Official Use Only" as For
Official Use Only (FOUO)

Security Terms as defined by Department of
Energy in a draft security guide.


Atomic Energy Commission (AEC) - A five-member commission and
supporting organization established by the AEA of 1946 to manage
the U.S. civil and military nuclear energy programs. Succeeded
by the Energy Research and Development Agency (ERDA) and the
separate Nuclear Regulatory Commission (NRC)) in 1974 and then
by the current Department of Energy (DOE) in 1977.

Classification - The determination by an authorized official
that information requires protection under the provisions of an
Executive order (for NSI) or that a document or material
contains classified information for NSI, RD, or FRD.

Confidential (C) - Currently the lowest classification level;
applied to information whose unauthorized disclosure could
reasonably be expected to cause damage to national security.

Declassification - A determination by appropriate authority in
accordance with approved classification policy that information
is no longer classified or that a document or other material no
longer contains classified information.

Executive Order (EO) - Formal Presidential order mandating
activities of the Executive Branch. As used here, Executive
orders concern the identification and protection of classified
national security information, such as the current Executive
Order 12356.

Formerly Restricted Data - Classified information jointly
determined by DOE and DOD to be related primarily to the
military utilization of atomic weapons and removed by DOE from
the Restricted Data category pursuant to section 142d. of the
Atomic Energy Act. FRD is protected as NSI except for the
purpose of foreign dissemination, where it is treated as RD.

L-Clearance - DOE or NRC clearance for access to CRD, SFRD, or

National Security Information (NSI) - Information that has been
determined pursuant to Executive Order 12356 or any predecessor
order to require protection against unauthorized disclosure and
that is so designated. Note that only DOE uses "NSI" markings on

Need-To-Know - A determination by a person having responsibility
for classified information or material that a proposed
recipient's access to such classified information or matter is
necessary in the performance of official or contractual duties
of employment.

Official Use Only (OUO) - A designation identifying certain
unclassified but sensitive DOE information that may be exempt
from public release under the FOIA.

Q-Clearance - DOE or NRC clearance for SRD, TSFRD, or TSNSI.

Restricted Data (RD) - A category of classified information
defined by the AEA, sec 11.y.: "The term 'Restricted Data' means
all data concerning (1) design, manufacture, or utilization of
atomic weapons; (2) the production of special nuclear material;
or (3) the use of special nuclear material in the production of
energy, but shall not include data declassified or removed from
the Restricted Data category pursuant to section 142"

Secret (S) - The classification level between Confidential and
Top Secret; applied to information whose unauthorized disclosure
could reasonably be expected to cause serious damage to the
national security.

Security - The protection of valuable matter, including
classified material and information.

Security Clearance - Official determination that access by an
individual to classified information will not be inimical to
national security; e.g., in DOE (and NRC) "L-" and "Q"-
 clearances for RD, FRD and NSI, and "S" and "TS" clearances for
NSI only. "C", "S", and "TS" clearances are used in other
agencies for NSI.

Sensitive Compartmented Information (SCI) - Classified
information concerning or derived from intelligence sources,
methods, or analytical processes, which is required to be
handled within formal access control systems established by the
Director of Central Intelligence.

Top Secret (TS) - The highest classification level; applied to
information whose unauthorized disclosure could reasonably be
expected to cause exceptionally grave damage to national

Unclassified - The designation for information, a document, or
material that has been determined not to be classified or that
has been declassified by proper authority.
