Survivability
In Network Systems
Contemporary large-scale networked systems that are highly distributed improve
the efficiency and effectiveness of organizations by permitting whole new levels
of organizational integration. However, such integration is accompanied by elevated
risks of intrusion and compromise. These risks can be mitigated by incorporating
survivability capabilities into an organization's systems. As an emerging discipline,
survivability builds on related fields of study (e.g., security, fault tolerance,
safety, reliability, reuse, performance, verification, and testing) and introduces
new concepts and principles. Survivability focuses on preserving essential services
in unbounded environments, even when systems in such environments are penetrated
and compromised.
The
New Network Paradigm: Organizational Integration
From their modest beginnings some 20 years ago, computer networks have become
a critical element of modern society. These networks not only have global reach,
they also have impact on virtually every aspect of human endeavor. Network systems
are principal enabling agents in business, industry, government, and defense.
Major economic sectors, including defense, energy, transportation, telecommunications,
manufacturing, financial services, health care, and education, all depend on a
vast array of networks operating on local, national, and global scales. This pervasive
societal dependency on networks magnifies the consequences of intrusions, accidents,
and failures, and amplifies the critical importance of ensuring network survivability.As
organizations seek to improve efficiency and competitiveness, a new network paradigm
is emerging. Networks are being used to achieve radical new levels of organizational
integration.
