Study Notes

Real Time Responder Roles

Read Only Analyst includes roles like C.Falcon Analyst and D.Real Time Responder – Active Responder.
Active Responder enables real-time detection and response actions.

Reducing False Positives

Reduce false positives for code execution flagged during testing by using a Containment Policy.
Development work must be stored in a designated file share, "devcode."

Disabling Detections on Hosts

It's not permissible to disable all detections on individual hosts as it increases risk.

Windows Sensor Update Policies

There are no "Auto" sensor version update options available for Windows Sensor.

Policy Management in Falcon

Policy alignment is configured in the General Settings section under the Configuration menu.
Prevention policies must be aligned with specific host groups for proper deployment.

Operating System Considerations

Separate sensor update policies for Windows, Mac, and *nix are critical for auditing requirements.
Each OS may have unique considerations impacting policy deployment and efficacy.

Assigning a Policy to Host Groups

Assign policies to groups using tag assignments in Host Management to streamline management procedures.

Creating API Clients

It is essential to immediately save the secret when creating an API client, as it cannot be viewed again.

Reduced Functionality Mode (RFM)

Hosts may enter Reduced Functionality Mode if a host is offline for over 24 hours due to sensor communication issues.

Sensor Communication Settings

The CrowdStrike Sensor communicates using TCP port 443 (HTTPS) for secure data transmission.

Obtaining Windows Sensor Installer

Windows sensor installers are accessible via the Hosts > Sensor Downloads section in the Falcon interface.
