Computer
Security
(COMPUSEC)
The totality of security safeguards needed to provide acceptable level of
protection for automatic data processing (ADP) systems and the classified data
processed. Includes all hardware/software functions, characteristics, features;
operational, accountability, and access control procedures at the computer and
remote terminal facilities; and, the management constraints, physical structures,
and devices needed to provide an acceptable level of protection for classified
information in any state of storage, processing, display or communication within
the ADP system.
Computer
Software
Configuration
Item (CSCI)
An aggregation of software that satisfies an end use function and is designated
by the Government for separate configuration management. They are selected
based on tradeoffs among software function, size, host or target computers,
developer, support concept, plans for reuse, criticality, interface considerations,
need to be separately documented and controlled, and other factors.

Concept
Exploration &
Definition
The initial phase (Phase 0) of the system acquisition process, beginning at
Mission Need Determination. During this phase, the acquisition strategy is
developed, system alternatives are proposed and examined, and the system
program requirements document is expanded to support subsequent phases.
Concept of
Operations
(CONOPS)
(1) A statement, in broad outline, of a commander’s outline or intent in regard to
an operation or series of operations. The concept is designed to give an overall
picture of the operation. (MDA Lexicon)
(2) A verbal or graphic statement, in broad outline, of a commander’s
assumptions or intent in regard to an operation or series of operations. The
concept of operations frequently is embodied in campaign plans and operation
plans; in the later case, particularly when the plans cover a series of connected
operations to be carried out simultaneously or in succession. The concept is
designed to give an overall picture of the operation. It is included primarily for
additional clarity of purpose.
Concept Plan An operation plan in concept format. Also called CONPLAN.
Concurrency Part of an acquisition strategy which combines or overlaps two or more phases of
the acquisition process, or combines development T&E with operational T&E.
Concurrent
Engineering
A systematic approach to the integrated, simultaneous design of products and
their related processes, including manufacture and support. This approach is
intended to cause developers, from the beginning, to consider all elements of
the system life cycle from requirements development through dispersal, including
cost, schedule, and performance.
CONEX CONOPS Exerciser.
Configuration A collection of an item’s descriptive and governing characteristics, which can be
expressed in functional terms (i.e., what performance the item is expected to
achieve); and in physical terms (i.e., what the item should look like and consist of
when it is built).

Configuration
Audit
One of the Configuration Management tasks which includes a functional
configuration audit (FCA) to validate that the development of a configuration item
has been completed satisfactorily and that the configuration item has achieved
to specified performance and functional characteristics, and also includes a
physical configuration audit (PCA) to verify that the configuration item “As Built”
conforms to the technical documentation which defines the configuration item.
Configuration
Baseline
The configuration documentation formally designated by the Government at a
specific time during a system’s or configuration item’s life cycle. Configuration
baselines, plus approved changes from those baselines, constitute the current
configuration baselines, namely the functional, allocated, and product baselines.
Configuration
Control
One of the Configuration Management tasks that involves the systematic
evaluation, coordination, approval, or disapproval of proposed changes to the
design and construction of a configuration item whose configuration has been
formally approved.
Configuration
Identification
One of the Configuration Management tasks, which require that for every
