Incident Detection & Response - How to avoid the 10 most common mistakes

Discovering cyber attacks quickly and reacting appropriately is more important today than ever. Technology alone is not enough. Decisive factors are an experienced Incident Detection & Response (IDR) Team and suitable processes. In practice, it has been shown: Especially with complex attack scenarios, there is still much need for optimisation.

Almost every second German company has been the victim of cyber attacks in the last two years, according to a recent Kaspersky study. The threat situation is rising. As digitisation increases, the attack surface grows, while hackers develop more and more advanced attack methods. Even the best technology will never completely eliminate the risk of cyber incidents. It is all the more important to detect a successful attack as quickly as possible and to take the right measures to minimise damage. After even just one week, the costs will more than double compared to if the incident is detected early on.

Most companies are aware of this urgency. Some therefore have established Incident Detection & Response teams and work with SIEM systems that evaluate log files and raise alarms when they detect evidence of security incidents. However, in practice, it has been shown that IDR teams and processes often reach their limits, especially with complex attack scenarios.

Communication and organisation are the main weak points

Since 2017, CYOSS has regularly conducted specialised training for IDR teams in its Cyber Simulation Center. During these trainings, we noticed that many companies still need to optimise and do not exploit their full potential. The biggest IDR weak points are usually in communication and organisation.

Usually it only becomes clear in a real-life situation how well IDR teams and processes actually work. Therefore, regular training is important to test complex attack scenarios and establish best practices. In addition, IDR teams should continually evolve to meet the growing threats.
