CrowdStrike Falcon Analyzers#
This documentation covers the setup and usage of CrowdStrike Falcon analyzers for retrieving device information, vulnerabilities and alerts linked to a given hostname observable, as well as performing file analysis using the CrowdStrike Falcon Sandbox.
Pre-requisites#
To use these analyzers, you must have the following configured in your CrowdStrike Falcon tenant:
- CrowdStrike Falcon Setup:
- Log in to your CrowdStrike Falcon tenant.
- Navigate to Support and resources > Resources and tools > API clients and keys.
- Create an API Client with the required permissions:
- Hosts: Read (for
getDeviceDetailsandgetDeviceVulnerabilities). - Vulnerabilities: Read (for
getDeviceVulnerabilities). - Alerts: Read (for
getDeviceAlerts). - Sandbox (Falcon Intelligence): Read, Write (for
Falcon Sandbox).
