gofalcon

Golang-based SDK to CrowdStrike's Falcon APIs.

Gofalcon documentation is available on pkg.go.dev. Users are advised to consult this gofalcon documentation together with the comprehensive CrowdStrike API documentation published on Developer Portal. The easiest way to learn about the SDK is to consult the set of examples built on top of the SDK. What follows is a subset of these examples that can be found useful as stand-alone programs.

Example	Description
falcon_sensor_download	stand-alone tool that can be used to download CrowdStrike Falcon Sensor
falcon_event_stream	stand-alone tool that can be used to stream events as they happen in CrowdStrike Falcon Console
falcon_cleanup_pods	stand-alone tool that can be used to clean-up inactive pods from CrowdStrike Falcon Console
falcon_cspm_ioms	stand-alone tool that leverages CrowdStrike Cloud Security Posture Management (CSPM) to list indicators of misconfigurations (IOMs)
falcon_detection_details	stand-alone tool that outputs inventory of all Falcon Detections based on custom filter
falcon_discover_host_details	stand-alone tool that can be used for auditing purposes and for gaining timely visibility into your environment
falcon_get_cid	stand-alone tool that can be used to get Customer ID based on the API key pair
falcon_iocs	stand-alone tool that can be used to add, delete or list Custom IOCs in the CrowdStrike Falcon Console
falcon_intel_indicators	stand-alone tool that queries CrowdStrike Intelligence Indicators
falcon_intel_rules_download	stand-alone tool that downloads CrowdStrike Falcon Intelligence Rule files
falcon_host_details	stand-alone tool that outputs inventory of hosts registered to CrowdStrike Falcon platform
falcon_registry_token	helper to generate container registry logic information for docker login
falcon_spotlight_vulnerabilities	stand-alone tool that outputs inventory of vulnerabilities affecting your environment
falcon_supported_kernels	stand-alone tool that outputs short list recent Linux kernels supported by CrowdStrike Falcon for a given distribution
falcon_zta	stand-alone tool that utilises Hosts and ZTA APIs and outputs ZTA findings for your environment

Gofalcon is an open source project, not a CrowdStrike product. As such, it carries no formal support, expressed or implied.

Gofalcon is periodically refreshed to reflect the newest additions to the CrowdStrike API. Users of the SDK are advised to track the latest releases rather closely to ensure proper function in the unlikely event of an incompatible change to a CrowdStrike API.

Installation

go get github.com/crowdstrike/gofalcon/falcon

Usage Example

Various real-life examples can be found in the examples/ directory. The bare minimum example follows.

package main

import (
	"context"
	"fmt"

	"github.com/crowdstrike/gofalcon/falcon"
	"github.com/crowdstrike/gofalcon/falcon/client/incidents"
)

func main() {
	client, err := falcon.NewClient(&falcon.ApiConfig{
		ClientId: "FILL-IN-HERE",
		ClientSecret: "FILL-IN-HERE",
		Context: context.Background(),
	})
	if err != nil {
		panic(err)
	}

	desc := "timestamp.desc"
	res, err := client.Incidents.CrowdScore(&incidents.CrowdScoreParams{
		Context: context.Background(),
		Sort: &desc,
	})
	if err != nil {
		panic(err)
	}
	payload := res.GetPayload()
	fmt.Printf("As of %s your CrowdScore is %d.\n",
		payload.Resources[0].Timestamp.String(), *payload.Resources[0].Score)
}
