The Importance of Threat Hunting

"Threat Hunting" - NY Metro InfraGard/HTCIA Joint Security Summit

Organizations should constantly be on alert for possible cyber threats lurking around, given the rapidly evolving tactics, weapons, and technologies that hackers use. Unfortunately, it doesn’t make it any better knowing that no cybersecurity system is impenetrable or capable of stopping every potential threat. Cyber threat hunting is an essential exercise to proactively investigate potential compromises, detect advanced threats, and improve cyber defenses. Some threats may even be unidentified or unknown to the organization until the damage has already been done.

Threat hunting combines the use of human talent and engineering to seek Indicators of Compromise (IOC). With threat hunting, threat intelligence analysts are able to familiarize themselves with an organization’s environment and are able to effectively filter out key events that need to be examined closer. Analysts can also find and identify possible targets, then interpret patterns around the attack.

This process allows to proactively uncover hidden threats and detain them, increase the accuracy of catching these threats, and reduce the likelihood of an incident. The quicker active threats are identified and communicated to an incident responder, the quicker the threat will be neutralized before more damage to network and data occurs. Cyber threat hunting allows for gathering essential data to investigate incidents that have already occurred. This in turn, creates a more effective response and action toward future threats exposing the organization to danger.

As cyber threats are a constant issue, it is important for organizations to implement this exercise to effectively identify and protect themselves from potential attacks.
