The Customer ID (CID) is a unique alphanumeric string that associates a CrowdStrike Falcon sensor with a specific customer's cloud environment. During the sensor installation process, particularly when using the command-line interface (CLI) or automated deployment scripts, the CID must be provided as a provisioning parameter. This ensures that the newly installed sensor registers with the correct Falcon console, receives the appropriate policies, and reports its data to the right tenant. Without the CID, the sensor cannot be provisioned to a customer's environment.

A. Adding a user is performed by an administrator within the Falcon console; the CID is not a manually entered parameter for this action.

C. API keys are generated within the context of an authenticated session in the Falcon console, which is already tied to a specific CID.

D. A host search is conducted within the Falcon console where the user is already operating under the scope of their organization's CID.

1. CrowdStrike Falcon Documentation

Sensor for Windows: Deployment Guide. In the "Install the sensor from the command line" section

the documentation specifies the syntax for installation

which includes the CID as a mandatory parameter. For example: msiexec.exe /i /qn CID=. This demonstrates the CID's critical role in the installation process.

2. CrowdStrike Falcon Documentation

Sensor for Linux: Deployment Guide. The "Install the sensor" section details the command-line installation process for various Linux distributions (e.g.

using rpm or dpkg). It explicitly states the requirement to provide the CID during installation to associate the sensor with the customer's cloud

such as: sudo yum install .rpm --enablerepo=extras --disablerepo=amzn-main CID=.

3. CrowdStrike Falcon Documentation

Users and Roles. The documentation for user management details the process of inviting and managing users through the Falcon UI. The process relies on email invitations and role assignments

not the direct input of the CID by the administrator performing the action.
