© Springer Nature Switzerland AG 2019. Organizations increasingly rely on complex networked systems to maintain operational efficiency. While the widespread adoption of network-based IT solutions brings significant benefits to both commercial and government organizations, it also exposes them to an array of novel threats. Specifically, malicious actors can use networks of compromised and remotely controlled hosts, known as botnets, to execute a number of different cyber-attacks and engage in criminal or otherwise unauthorized activities. Most notably, botnets can be used to exfiltrate highly sensitive data from target networks, including military intelligence from government agencies and proprietary data from enterprise networks. What makes the problem even more complex is the recent trend towards stealthier and more resilient botnet architectures, which depart from traditional centralized architectures and enable botnets to evade detection and persist in a system for extended periods of time. A promising approach to botnet detection and mitigation relies on Adaptive Cyber Defense (ACD), a novel and game-changing approach to cyber defense. We show that detecting and mitigating stealthy botnets is a multi-faceted problem that requires addressing multiple related research challenges, and show how an ACD approach can help us address these challenges effectively.
