vulnerability assessment is the process of identifying,
quantifying, and prioritizing (or ranking) the
vulnerabilities
in a system. Examples of systems for which vulnerability assessments are
performed include, but are not limited to, information technology systems,
energy supply systems, water supply systems, transportation systems, and
communication systems. Such assessments may be conducted on behalf of a range
of different organizations, from small businesses up to large regional infrastructures.
Vulnerability from the perspective of disaster management means assessing the
threats from potential hazards to the population and to infrastructure. It may
