Yet a serious cyberattack can still disrupt operations, damage customer trust, and leave teams unsure which systems and data they can rely on. This is driving a shift in cybersecurity, moving beyond preventing attacks toward building organizations that can withstand disruption, recover safely and learn from incidents. That is the essence of cyber resilience. The National Institute of Standards and Technology (NIST), in its publication Developing Cyber-Resilient Systems: A Systems Security Engineering Approach, explains how resilience can be designed into systems rather than treated as an afterthought. The lesson is simple: security is not just about keeping threats out. It is also about ensuring that a successful attack does not bring everything down. Cybersecurity is not the same as cyber resilience Organizations work to close vulnerabilities, restrict access, monitor suspicious activity and prevent unauthorized users from reaching sensitive systems.…
