Cyber Resilience is a holistic strategy to strengthen the resilience of an organization’s IT against cyber attacks. Among other things, cyber resilience includes the concepts of cyber security and business continuity management. It is designed to prevent attacks on IT and ensure secure continued operations and rapid resumption of operations.

What is Cyber Resilience?
Cyber Resilience goes far beyond pure cyber security and takes a comprehensive approach to protect IT from cyber-attacks and ensuring and resume operations after attacks have occurred. The measures and concepts of cyber security, computer forensics, information security, disaster recovery, and business continuity management are components of this approach.
The goal is to create a high level of robustness in the IT infrastructure of a company or organization in the face of the various threats and to minimize risks for operational failures. The ultimate goal is to ensure the continued existence of the company or organization.
The EU-wide NIS Directive (Directive on Security of Network and Information Systems) is intended to provide a high level of resilience for organizations operating critical infrastructure. Resilience affects many areas of an organization and must be anchored in management. It is an integral part of all processes and all employees must be made aware of it.
Cyber security measures to avert threats and increase the level of security form the basis. In addition, processes for disaster recovery and restoring operations after successful attacks must be prepared.
Important prerequisites of cyber resilience
An important prerequisite for the success of a resilience program is an active drive of all activities by management. Interdisciplinary teams identify and manage risks to various systems and environments.
The identified risks must be regularly assessed and updated. In principle, a constant threat situation is to be assumed in the entire program. In the event of a crisis, crisis management must be constantly trained and the various measures of the crisis response processes must be prepared.
Comparison of Cyber Resilience and Cyber Security
Cyber security is an important component of cyber resilience. However, fundamental differences can be noted in the way problems are viewed and approached. While cyber security defines methods, processes, and measures to protect data, networks, and IT systems from cyber attacks, thereby reducing the risk of becoming a victim of an attack, resilience is not limited to risk minimization but provides measures, processes, and methods to ensure operations during an attack or to quickly resume operations after an attack.
It, therefore, ensures a high level of resilience and robustness for the entire organization and IT infrastructure. Basically, the concepts of resilience are intended to ensure a secure operating state in all situations and threat situations. Resilience programs require holistic thinking and fast, agile action in the event of attacks. Security and resilience become part of the daily work in all areas of the organization.
