The truth is that threat hunt end goal plays an important role in the whole classification of the type of the hunt. Hunt events start with a concrete goal to discover specific actors—which classifies this type of hunt as a threat focused. Likewise, an environmental hunt engagement focused on learning a particular subset of the overall environment from a technical angle. Classifying the type of a threat hunt is as essential as the type of threat hunt changes the TTP and data sources required to conduct the hunt. A hunt might also start as an environmental hunt and might change into a threat-focused hunt as any malicious activity be discovered.
To make the issue a little more difficult, not all analysts use the same techniques or methods to achieve their goals. For example, a nation state actor could have a set of known techniques tactics and procedures (TTPs) that could potentially be detected. If the TTPs changed, what new course of actions would the analyst take? Or even more frustrating, what if an insider was operating in the grounds of a company policy to steal data? The detection line grows and might even be non-existent in the case of an insider leaking information until the damage is done.
Organizations spend most of their money and resources on security, sometimes more than actual operations. Because they understand that the unauthorized revealing of a single bit of code could possibly put an end to their business. However, none is immune to cyber-attacks. Security professionals within the organization would equip their defense with all the tools they can accommodate assuming to deter any attacker. This is like a wild fire. Along with the new tools they bring new vulnerabilities to the Network infrastructure. Above all, attackers are so patient to wait for the right chance to get access to your data as they know it values a lot. Even the smallest negligence in security infrastructure could be an invitation to the attacker.
One possible way to increase the immunity and shield the business from this war is to sometime wear the hat of an attacker and attack your own organization without any mercy in all possible ways. Now sit back, review how could you compromise such a strong security, find the gaps and fill it. In simple terms, perform Threat Modeling.
