Threat hunting, cyber threat hunting or proactive threat hunting, is the seeking out of unknown threats to a network. Threat hunting involves actively searching through endpoints, networks, systems, applications, sources, and datasets in order to hunt or identify malicious or suspicious activity.
Threat hunters dig deep into the backends of websites to find anomalies and issues that may lead to an attack on the network. It’s a manual process that involves IT security analysts thoroughly scrutinizing the data in their networks. Threat hunters utilize several tools, including automation, machine learning and behavioral analytics solutions to identify potential threats.
Cyber threat hunters usually leverage log data, permission, and comparative approaches to help them identify abnormalities. Baselining, for example, helps threat hunters understand how their networks would look under normal conditions. From there, they can begin to identify abnormalities in the network and single out malicious behavior.

While threat detection or automated triggers help find potentially harmful material in your networks, these are still somewhat passive approaches that should work alongside a cyber threat-hunting strategy. Threat hunting follows a series of steps that ensure a thorough and effective hunt. These steps include:
Ideally, threat hunting is happening all the time. The idea behind threat hunting is proactive security.
In practice, this may mean monthly, bi-weekly, and weekly checks and scans through log data and other relevant network features. Only by examining large pools of crowdsourced data and log data on a regular basis can threat hunters gain insight into attack tactics and respond accordingly with the steps listed above.
There are several tools that provide IT teams with the capability and power to engage in competent threat hunting. Some of these tools provide IT teams with the space to reallocate time to threat hunting, while others provide automation functionalities that assist threat hunters to get through their steps more efficiently and quickly.
