Every day, cyber threats evolve and expand, necessitating more significant investment in security operations and response procedures. Advanced threats can remain undiscovered in our environment for months at a time, gathering our vital information. Threat hunting can assist in overcoming these obstacles.
What is threat hunting?
Threat hunting is the process of searching for cyber threats that are lying undetected in a network. It can be analogous to traditional hunting.
Even with the most modern technology, there is always the possibility that some advanced threat will circumvent the various security layers defending a corporation, which is what we are looking for. Threat hunting is a proactive technique that supplements the reactive approach of regular SOC activity.
Threat hunting entails:
Hunting for threats that exist within the organization
Hunting for threats pro-actively on the internet
Hunting for threats using a trap
Three factors determine threat hunting's potential output:
Visibility
Skills
Threat intelligence

Tips to improve security through threat hunting:
You should prioritize based on context:
Effective prioritization necessitates context to comprehend what is relevant and high-priority to your organization. Your high-value resources will not waste time chasing false adversaries or threats if you take a threat-hunting approach that includes aggregating, scoring, and prioritizing within the context of your environment.
You should always learn and enhance your knowledge and skills:
Threat hunting must be a continual effort, not a one-time event. Threat Hunters stay up to date on current and upcoming threats, tools, and tactics hackers use.
You should know your environment well:
Threat Hunters must devote significant time to learning about regular and routine activities in their surroundings. Analysts must comprehend the entire architecture, which includes systems, applications, and networks. Threat Hunters must work as effective change agents, which requires a trusting relationship.
You should have adequate and appropriate resources:
Sufficient resources, including persons, systems, and technologies, are required to undertake threat hunting effectively. Personnel must be well-versed in operating systems and subsystems, including application servers, web servers, and database servers. Understanding the CB Response tool is also beneficial.
You can collaborate with other professionals:
Analysts must be able to perform collaborative investigations to find and compare indicators throughout your infrastructure. Collaboration is included throughout all processes, including threat hunting, using a single shared environment. Teams can collaborate to investigate every nook and cranny of the company in order to identify adversary techniques.
You should protect all endpoints:
It is critical to protect all endpoints since failure to do so may open doors for adversaries. Endpoint security is provided by the security software installed on a network's centrally managed server or gateway, and antivirus software alone cannot protect against Advanced Persistent Threats (APTs).
Final words:
Security teams should implement intelligence analysis solutions that include threat hunting as part of their security strategy. This allows you to prepare for an attack before it happens. If you want to learn more about threat hunting, enroll in InfosecTrain’s threat hunting training course.
