Answering Questions Before They’re Asked (Guest Article by Chris Sanders)
Investigations are all about iterating through evidence that helps you make decisions about what events transpired on your network. That sounds easy enough, but asking the right questions and identifying the data you need to answer them is tricky. This problem manifests in two ways. First, not having enough of the right data means you may be unable to answer the questions that will move the investigation forward. Conversely, having too much data may be overwhelming with a tremendous number of fi ...

Retracing Investigation Steps When Threat Hunting
Finding evil is all about asking the right questions, finding answers, and using those answers to ask more questions. Each question and answer represent a decision point, branching the investigation off down a new path. The path of the analyst is far from linear, and sometimes we need to go back and retrace our steps to work from a previous decision point. Just like Hansel and Gretel left breadcrumbs along their path through the woods, we too need breadcrumbs to ensure that we’re fully explori ...

This interview by TAG Cyber CEO Ed Amoroso was originally published here. The proper role for humans in real-time cyber security has not always been crystal clear. My belief two decades back was that automation should feed prioritized alarms to friendly operators wearing headsets (think colorful ADT brochure), and that customers would receive timely notifications whenever something was amiss in their network. It was a logical, attractive view of cyber operations – and it was wrong. The problem ...
