Summary : Threat Hunting refers to proactively and iteratively searching through networks or datasets to detect and respond to advanced threats that evade traditional rule- or signature-based security solutions. But what does this really mean? And what real impact does it have on the security team?
Can we use threat hunting to provide a process to better detect and understand when you've been breached?
More and more security data is being produced and usually aggregated into a central location or body to hopefully take quick and informed decisions on attacks or compromises amongst a mountain of data. When you start to include data gathered from your endpoints the amount of data starts to explode exponentially. This level of data provides us with a large amount of visibility. But is having visibility enough?
What if a more thoughtful and intelligent way of generating alerts could draw an analysts attention to the right place at the right time? This would provide context or even flag indicated suspicious behaviour that can become the starting point of a hunt.
In this talk, we will explore this theory and establish working foundations of what threat hunting is and look at some of the challenges associated with gathering large data sets. This will give us a foundation to look at how we can improve and explore implementing an intelligent threat hunting model to drive the investigation process.
