Titel: From Network Intrusion Detection To Threat Hunting

Abstract
Cyber attacks pose one of the most challenging risks that many organizations face today. Reports of compromises & leaks are making the mainstream news on a daily basis now, affecting targets from the smallest mom-and-pop online store to national critical infrastructure. Regularly, even some of the best protected networks discover that attackers have been roaming around inside for months unnoticed. While researchers and industry alike have been developing intrusion detection systems for decades, these evidently remain unable to find many such attacks. In this lecture, we revisit some of the classic intrusion detection approaches, along with their challenges and shortcomings in practice. We then examine a different, proactive approach that an increasing number of organizations is now turning to: "threat hunting" flips intrusion detection upside-down by starting with an assumption of attackers likely being inside the network *already*, and then relying primarily on the expertise & skill set of human analysts to uncover them. While intrusion detection and other automation do remain in place, they now support the analysts' investigation rather than drive the process. We conclude by looking at one of the most popular tools among threat hunters: Zeek (formerly Bro), an open source network security monitor providing comprehensive visibility into a network's operation.
