Description / Abstract:
This part of ISO/IEC 15026 specifies the concept of integrity
levels with corresponding integrity level requirements that are
required to be met in order to show the achievement of the
integrity level. It places requirements on and recommends methods
for defining and using integrity levels and their corresponding
integrity level requirements. It covers systems, software products,
and their elements, as well as relevant external dependences.
This part of ISO/IEC 15026 is applicable to systems and software
and is intended for use by the following:
a) definers of integrity levels such as industry and
professional organizations, standards organizations, and government
agencies;
b) users of integrity levels such as developers and maintainers,
suppliers and acquirers, system or software users, assessors of
systems or software and administrative and technical support staff
of systems and/or software products.
One important use of integrity levels is by suppliers and
acquirers in agreements; for example, to aid in assuring safety,
financial, or security characteristics of a delivered system or
product.
This part of ISO/IEC 15026 does not prescribe a specific set of
integrity levels or their integrity level requirements. In
addition, it does not prescribe the way in which integrity level
use is integrated with the overall system or software engineering
life cycle processes. It does, however, provide an example of use
of this part of ISO/IEC 15026 in Annex A
