For more information, see the Auto Block Bad Hashes article.Like most advanced endpoint solutions, CrowdStrike Falcon: Write permission is required to block hashes through auto-remediation. Write: Create, modify, or delete your custom IOCs. Read: Search your custom IOCs and view hosts that observed your custom IOCs. Write: Run RTR commands that send information to a host, equivalent to the RTR Active Responder role. Read: Run RTR commands that get information from a host, equivalent to the RTR Read OnlyAnalyst role. To select Incidents, you need Falcon Insight XDR enabled. Read is required to allow Expel to Mark alerts as 'in-progress' when Expel processes them. Write: Perform actions on incidents, such as adding tags or comments or updating the incident name or description. Read: Search and view details on incidents and behaviors. For more information, see the CrowdStrike Auto Host Containment article. Write permission for Hosts is required for Auto Host Containment. Write: Take action on hosts, including containing or lifting containment on a host. Details include OS type and version, sensor version, assigned policies, containment status, and more. Read: Search for hosts and get host details, using standard or scrolling pagination. Write permission is only required to use the Mark in Progress option in CrowdStrike. Write: modify metadata about a detection, such as its status, assignee, and description. Read: view information about a detection, such as its behavior, severity, associated host, timestamps, and so on. You must request from CrowdStrike that Expel can have this access to your console and verify Expel is allowed to have it.Īfter CrowdStrike sets up this access, Expel is assigned these 4 roles in your console: This allows Expel to use the Expel FlightControl account to log into your device. Step 1: Enable console accessĮxpel is a CrowdStrike Certified Managed Security Provider partner. Ultimately, the more permissions you can grant Workbench, the better and faster the SOC analysts can find and investigate alerts in your environment. Depending on what your organization purchased from Expel, the SOC analysts may even be able to contain and/or remediate the issues on your behalf. It also allows our SOC analysts to perform health checks to make sure Workbench is not missing alerts from your security devices. Allowing Expel visibility into the console of your security devices helps our SOC analysts make better decisions on whether an alert is benign or malicious. If you grant Read access to your devices, we can investigate the device and the logs more deeply and surface relevant alerts to you in Workbench. This can mean they surface more benign alerts to your team for further investigation, resulting in increasing the workload for your team, and resulting in alert fatigue. Without minimum permissions to your devices, the SOC analysts are limited in their insight into your technology. These permissions vary from 1 device technology to another, but we typically need at least Read access to your devices to pull in any logs from those devices into Workbench. Depending on your settings, Workbench can auto-remediate or send to an Expel analyst for further investigation.Īll Expel detections for CrowdStrike Falcon are available in the Expel Workbench in the Detections area.Ībout console permissions in your devicesĪs you connect your devices to Workbench, you provide Workbench access to those devices through permissions in the devices. Workbench adds context, enriches with intel, and assesses the risk. Real Time Response also allows analysts to connect to a host, typically to query information and pull files.Īfter you connect CrowdStrike to Workbench, Workbench ingests Crowdscore Incidents. This means that analysts generally need to do their own investigation using Event Search. But CrowdScore logs alone don't typically have full process genealogy / indicators associated with them. The Expel alert poller consumes all Falcon alerts except Machine Learning and Cloud-based ML with a vendor severity of Information or Low.ĬrowdScore in CrowdStrike delivers prioritized incidents to streamline the triage process and help analysts focus on the most critical threats first. And not all CrowdStrike alerts need attention.ĬrowdStrike Falcon generates various alert types, which consist of a Mitre ATT&CK based detection framework. CrowdStrike logs include a great deal of information that can take hours to manually review. Connecting your device to Workbench allows Workbench to ingest the CrowdStrike logs.
