Definitions Edit

General Edit

Resilience is

the ability to resist, absorb, recover from, or successfully adapt to adversity or a change in conditions."[1]
the ability to reduce the magnitude and/or duration of disruptive events to critical infrastructure. The effectiveness of a resilient infrastructure or enterprise depends upon its ability to anticipate, absorb, adapt to, and/or rapidly recover from a potentially disruptive event.[2]
[t]he ability to adapt to changing conditions and prepare for, withstand, and rapidly recover from disruption.[3]
[t]he ability to quickly adapt and recover from any known or unknown changes to the environment through holistic implementation of risk management, contingency, and continuity planning.[4]
[t]he ability to prepare for and adapt to changing conditions and withstand and recover rapidly from disruptions; includes the ability to withstand and recover from deliberate attacks, accidents, or naturally occurring threats or incidents.[5]

Resilience is the adaptive capability of an organization in a complex and changing environment.[6]

Military Edit

Resilience is

the ability of an architecture to support the functions necessary for mission success with higher probability, shorter periods of reduced capability, and across a wider range of scenarios, conditions, and threats, in spite of hostile action or adverse conditions. . . . [R]esilience may leverage cross-domain or alternative government, commercial, or international capabilities.[7]

Overview (General) Edit

The challenge facing government is to maintain its role in protecting critical infrastructures, while determining how best to encourage market forces to improve the resilience of companies, provide appropriate incentives and tools to help entire sectors become resilient, and step in when market forces alone cannot produce the level of infrastructure security needed to protect citizens, communities, and essential economic systems.[8]

The goal of a resilient organization is to continue mission essential functions at all times during any type of disruption. Resilient organizations continually work to adapt to changes and risks that can affect their ability to continue critical functions. Risk management, contingency, and continuity planning are individual security and emergency management activities that can also be implemented in a holistic manner across an organization as components of a resiliency program.
