Critical IT security vulnerabilities are putting increasing pressure on businesses

A constant stream of new critical security vulnerabilities, cyber-attacks and IT system failures demonstrates that there is no such thing as 100 per cent security. It is therefore becoming increasingly crucial for businesses to be able to resume operations as quickly as possible in the event of an emergency. Professional IT emergency management is thus evolving from a technical precautionary measure into a strategic factor for success.

Whether it is a ransomware attack, a critical software vulnerability, an outage affecting a cloud service provider or a technical fault: IT disruptions can bring production, services and business processes to a standstill in a very short space of time. The economic consequences are often significant. “The question today is no longer whether companies can be affected by an IT crisis, but how well prepared they are for it,” explains Dr Christoph Thiel, a lecturer at the TÜV NORD Academy and a freelance consultant in the field of information security.

Emergency management ensures that critical processes, systems and data can be restored as quickly as possible even in crisis situations, thereby minimising downtime. Key components include the identification of business-critical processes, risk and business impact analyses, the definition of recovery times, and the establishment of clear responsibilities and crisis management structures. Equally important are regularly tested contingency plans, backup strategies and recovery processes.

The BSI Standard 200-4 and the international standard ISO 22301, amongst others, provide tried-and-tested guidance in this regard. Both approaches aim to strengthen organisational resilience and minimise the impact of disruptions on business operations. Regulatory requirements such as NIS2 create a further need for action. They place greater emphasis on corporate resilience and make contingency planning a key management task.

New technological developments such as artificial intelligence and, in the future, quantum computing are changing the risk landscape. Companies must therefore continuously review their contingency plans and adapt them to new threat scenarios. “Robust IT contingency management is not just a protective mechanism for emergencies, but an investment in a company’s future viability,” emphasises Dr Christoph Thiel. “Those who build resilience today ensure long-term stability, competitiveness and the trust of customers and business partners.”

The TÜV NORD Academy supports companies and professionals with qualifications, seminars and further training programmes covering information security, business continuity management, incident response, and the requirements of NIS2, ISO 22301 and BSI standards.
