Survivability: Protecting your critical systems

Survivability is the capability of a system to fulfill its mission in a timely manner in the presence of attacks, failures, or accidents. The emphasis of survivability is on continuity of operations, with the understanding that security precautions cannot guarantee that systems will not be penetrated and compromised. Survivability focuses on unbounded networked systems where traditional security measures are inadequate. As an emerging discipline, it builds on related fields of study (such as security, fault tolerance, reliability, and verification) and introduces new concepts and principles.
