Why this tool?

The goal of the GRR tooling is to support digital forensics and investigations. By using a fast and scalable model, analysts can quickly perform their analysis. One of the main features is the ability to search for particular information or details. This process is called hunting.

How it works

GRR uses a Python-based agent that is installed on the target systems. The server infrastructure, which also uses Python, perform the management and communicates with the client systems.

The analyst can use the central management console to configure flows. A flow has a particular task that may request for data on client systems. This could be retrieving something like a MAC address or looking for particular files on the system and show the details. The flows are used as part of a hunt, where one is actively seeking for the presence or the absence of some information. The analyst can take decisions based on the outcome.

Usage and audience

GRR Rapid Response is commonly used for digital forensics, intrusion detection, or threat hunting. Target users for this tool are forensic specialists, security professionals, and system administrators.
