Cyber resilience: The ability to prevent, prepare for, withstand and recover from cyberattacks and incidents. 
[BG] Киберустойчивост: Способността за предотвратяване, подготовка, устояване и възстановяване от кибератаки и инциденти.
Ciber-resiliencia / Resiliencia cibernética (Cyber resilience): Habilidad de prepararse para, adaptarse, soportar, y rápidamente recuperarse de interrupciones resultantes de ataques deliberados, amenazas o incidentes accidentales u ocurridos naturalmente. 
Sinónimo o equivalente a ciberresiliencia.
Resilience In the field of computing, the ability of an information system to withstand a breakdown or cyberattack and return to its initial operating state after the incident. 
Resilience En informatique, capacité d’un système d’information à résister à une panne ou à une cyberattaque et à revenir à son état initialaprès l’incident. 
Dengan pendekatan ini maka infrastruktur informasi kritis ini harus tahan terhadap ancaman, dan tetap dapat beroperasi untuk melayani publik walaupun terjadi ataupun kerusakan sebagian.
Cyber Resilience: The overall ability of systems and organisations to withstand cyber events and, where harm is caused, recover from them. 
Сајбер отпорност - способноста да се подготви, да се прилагоди, издржи и брзо да закрепне од пореметувања што произлегуваат од намерни напади, несреќи или природни закани или инциденти во сајбер просторот.  
Cyber resilience refers to an entity's ability to continuously deliver the intended outcome, despite adverse cyber events. It is the ability to prepare for and adapt to changing conditions and withstand and recover rapidly from disruptions. Cyber resilience focuses on the preventative, detective, and reactive controls in an information technology environment to assess gaps and drive enhancements to the overall security posture of the entity. 
Cyber resilience is the ability to prepare for, adapt to, withstand, and rapidly recover from disruptions resulting from deliberate attacks, accidents, or naturally occurring threats or incidents. 
المرونة وهي القدرة ع ى الاستعداد والتكيف مع الظروف المتغ يرة والصمود والتعا في ´ بسرعة من الاضطرابات ال ت ي تنتج عن الهجمات أو الحوادث المتعمدة أو تلك ال ت ي قد تحدث أ لسباب طبيعية. 
Rezilienţa infrastructurilor cibernetice: capacitatea componentelor infrastructurilor cibernetice de a rezista unui incident sau atac cibernetic şi de a reveni la starea de normalitate.
Cyber infrastructure resilience the capacity of infrastructure components to withstand cyber attack or cyber incident and return to normality. 
Cyber resilience – the overall ability of systems and organisations to withstand cyber events and, where harm is caused, recover from them. 
Information System Resilience: The ability of an information system to continue to: (i) operate under adverse conditions or stress, even if in a degraded or debilitated state, while maintaining essential operational capabilities; and (ii) recover to an effective operational posture in a time frame consistent with mission needs. (from: NIST SP 800-53 Rev 4) 
Cyber resilience is being able to prepare for, withstand, rapidly recover and learn from deliberate attacks or accidental events in the online world. 
To do this, people need to develop the skills, knowledge and understanding of the risk, in whatever setting they find themselves in, and then take the necessary steps to prepare for and respond to such events.
Cyber resilience means having appropriate internal cyber capability, strong governance and policy, strategic partnering, cyber situational awareness, ongoing cyber risk assessments (including understanding the risks and flow-on impact of a cyber breach), clear communication mechanisms, and a rapid cyber breach response capability. 
Cyber resilience is the organisation’s capability to withstand negative impacts due to known, predictable, unknown, unpredictable, uncertain and unexpected threats from activities in cyberspace (ISF 2011). 
Other International Definitions
Cyber resilience refers to the ability to continuously deliver the intended outcome despite adverse cyber events. 
The ability of systems and organizations to withstand cyber events, measured by the combination of mean time to failure and mean time to recovery.
