Explain the difference between reactive and proactive threat detection.
How do reactive threat detection and proactive threat detection differ? Analytics engines apply reactive threats in the SIEM, intrusion detection system IDS or endpoint sensors tools you will learn about later in this module. Proactive detections are made by threat hunters searching through the data based on threat intelligence information and internally generated intelligence.
According to a Threat Hunt survey conducted by the SANS Institute, of organizations report that they currently perform proactive threat hunting. However, these respondents noted that their proactive detections are relatively immature, with the biggest obstacles cited as a lack of skilled staff, budget constraints, and a lack of defined
processes.
In this TryIt Activity, you will first research a prevalent detected malware sample by digging into reports from a malware sandbox that detail its static and behavioral characteristics. Then, if endpoint monitoring capabilities discover this malicious code present or running on a system in your environment, the security operations team and incident responders would be called to take reactive actions in accordance with playbooks specific to the threat.
In the second part of this TryIt Activity, you will model proactive detection techniques similar to the actions of a threat hunter. Given a specific threat group, you will identify the tactics, techniques, and procedures unique to that actor. Based on your findings, you will formulate hunt hypotheses on how you may detect malicious activity attributed to this actor.
