A hunter wishing to bring food home for his or her family first needs to decide what type of animal he or she is going to target. Every quarry requires its own unique methods that dictate when the hunter goes out, where he or she goes, what kind of weapon to carry, and a host of other considerations.
In the world of cybersecurity, it’s no different. You don’t just “go threat hunting.” You need to have a target in mind, you need to look in the right places, and you need the right weapons.
In this white paper, we will discuss the minimum toolset and data requirements you need for successful threat hunting. We will take into account that, while some readers can devote most of their time to threat hunting, like most, you have limited time and resources for this activity. The good news is that threat hunting is flexible, and anyone can do it, regardless if you are spending just a few hours a week to full time.
Threat hunting is the process of proactively searching for malware or attackers that reside on your network. The generally accepted method is to leverage a security information and event management (SIEM) solution that centrally collects log data from disparate sources—endpoints, servers, firewalls, security solutions, antivirus (AV), and more—providing visibility into network, endpoint, and application activity that might indicate an attack.
The challenge with threat hunting is knowing what to look for. So, this white paper explores eight types of threat hunts that you can use to spot suspicious abnormalities that might be a leading or active indicator of threat activity. First, make sure you know the kinds of log data that are necessary to threat hunts.
