Due to many cyber attacks in the last years, governments are realizing how vulnerable they have become should there be a break out of a cyberwar. This urged them to establish a cyber warfare information infrastructure in a short time. However, this cyber warfare information infrastructure relies heavily on public infrastructures, like electricity and the Internet, which will be most likely targeted themselves. Therefore, a cyber warfare information infrastructure is by definition a vulnerable infrastructure that needs to be secured against attacks and made resilient. In this paper, we provide a method inspired by the theory of Complex Adaptive Systems to improve the resilience of cyber warfare information infrastructures. This method is applied on one specific security system as a showcase, namely, the intrusion detection system.
