Infrastructual security/Safeguarding critical infrastructures
Critical infrastructures are institutions and
facilities that are vital to the functioning of a public community. If they
fail partially or even completely, major supply bottlenecks and serious disruptions
to public safety and security can result. Because critical infrastructures are
increasingly interwoven and interdependent, serious incidents can set in motion
cascade or avalanche effects.
Last but not least, terrorist threat scenarios
are bringing the security of critical infrastructures to the fore in national
and private-sector security policy.
Institutions and facilities that need
safeguarding include energy supply, information technology, telecommunications as
well as transportation and traffic, e.g. airports. The mutual interdependence
of critical infrastructures is not limited to individual sectors but, because of
globalization, is increasingly transnational in nature. For example, countries
purchase energy from neighboring nations to ensure a continuous supply.
