Recently a number of open-source tools have been published that allow the timely acquisition and information extraction across an entire fleet of computers within a company or data center: GRR, MIG and osquery. They allow the remote acquisition of vital information dur- ing security incidents as well as monitoring of important parameters over time. All three are available as open source, are under active develop- ment and can be easily adapted to specific environments and contextual requirements. This talk will give an overview of these tools, how they scale to hundreds of systems and what their most fitting use cases are within entities con- trolling hundreds or thousands of PC systems. Each has its pros and cons, and depending on whether they are used for digital forensics, incident response or long-term monitoring of systems can make a difference.
