How is resilience defined in the context of information security?

Resilience in the context of information security refers to the comprehensive capability of an organization to prepare for, respond to, and recover from cyber incidents, while still sustaining its essential operations. This definition encompasses not only the response to incidents but also the proactive measures taken in anticipation of potential threats, ensuring that organizations can adapt and maintain integrity during disruptions.

This multifaceted approach recognizes that complete immunity from incidents is unrealistic, as no system can prevent all threats. Instead, resilience emphasizes the importance of preparedness and recovery processes. It reflects an understanding that while incidents may occur, the organization can still function and rebound effectively by having solid strategies and frameworks in place.

The other options do not fully capture the holistic nature of resilience; some focus narrowly on operational continuity, preventative measures, or data management without recognizing the dynamic interplay of preparation, response, and recovery needed in the face of cyber incidents.
