CrowdStrike Falcon Admin

9:15 AM, 7/31/2026

What is CrowdStrike / EDR

Endpoint Detection and Response (EDR), also referred to as endpoint detection and threat response (EDTR), is an endpoint security solution that continuously monitors end-user devices to detect and respond to cyber threats like ransomware and malware.

Demo: Overview of the Console

Endpoint security > Activity dashboard

  • Current CrowdScore: 0/100
  • New detections: 7
  • SHA-based detections
  • Prevented malware by host: None
  • Total OverWatch-analyzed events
  • OverWatch endpoint hunting leads
  • OverWatch endpoint detections triggered
  • CrowdScore over time
  • Most recent detections – 1 Critical and 2 High

Pages

  • CrowdScore incidents

Installation

Manual install (1-1)

  • Host setup and management > Sensor downloads > installer based on OS > download > copy CID
  • pkg file

Automatic install (1-many)

  • Host setup and management > Sensor downloads > installer based on OS > download > copy CID
  • Run on CLI

Points

  • Make sure OS matches
  • Sensor Release Matrix (N-1, N-2)
  • Network dependency: outbound SSL traffic (443)
  • Windows Installer
  • Linux Install
  • Installation Tokens > Add token
  • provisioning-token <token>, MAX 50 tokens per CID

Demo: Installing Sensors

  • Installing tokens -> Add Token (BTC install Token, 30 day)
  • See audit log
  • Require tokens checked

Sensor Downloads > Download Latest Sensor — How to Install

  1. Download the latest sensor installer for your platform.
  2. Copy your Customer ID checksum to enter during install: DA41AA34774B49BFB4BA5E88F0F91529-C2
  3. Run the installer on the endpoint. For installing via systems management tool or reusable VM images, see the Deployment Guides.
  • Download List -> Download -> CrowdStrike Falcon Sensor Setup dialog

Install command example (PowerShell):

PS C:\Users\hailie\Desktop> .\WindowsSensor.MaverickGyr.exe /install /quiet /norestart
CID=DA41AA34774B49BFB4BA5E88F0F91529-C2 MAINTENANCE_TOKEN=D299678E

PS C:\Users\hailie\Desktop> sc.exe query csagent

SERVICE_NAME: csagent
    TYPE               : 2  FILE_SYSTEM_DRIVER
    STATE              : 4  RUNNING
                              (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
    WIN32_EXIT_CODE    : 0  (0x0)
    SERVICE_EXIT_CODE  : 0  (0x0)
    CHECKPOINT         : 0x0
    WAIT_HINT          : 0x0

Troubleshooting

Uninstalling & Sensor updates

  1. Control panel > Programs and features > Uninstall
  2. Download a CS uninstall tool from Tool Downloads in console
  3. Support > Tool download > Sensor removal tool based on OS > download it

Uninstall via CLI:

csuninstalltool.exe MAINTENANCE_TOKEN=<token> /quiet
CsUninstallTool.exe /quiet
  • Cannot uninstall without a token if maintenance protection is enabled
  • Bulk maintenance mode
  • Bulk Uninstall

Host Management

Demo: Sensor Update Policies — BTC-Windows

  • Host targeting
  • Policy assignment
    • Prevention policies
    • Sensor update policies
  • Exclusions

Demo: Host Groups

Add New Group > New Group Details

  • NAME: BTC-Windows
  • DESCRIPTION: all hosts that are Windows OS
  • Group Type:
    • Dynamic: create a rule to automatically add/remove hosts based on filters
    • Static by host ID: add/remove hosts based on host ID
    • Static by hostname: add/remove hosts based on hostname
  • Edit > Filter (Platform: Windows) > 2 hosts > Save

Additional groups:

  • Host Groups > BTC-Windows page
  • New Group Details (BTC-MacOS, Dynamic) > Filter (platform: Mac)
  • New Group Details (BTC-Linux, Dynamic) > Filter (platform: Linux)

Prevention Policies

Prevention Policy: the set of rules controlling how the Falcon sensor detects and blocks malware/threats on a host — settings like malware prevention, exploit mitigation, and machine learning detection levels, applied to specific host groups. Without one assigned, a host is unprotected.

Make one:

endpoint security>prevention policies>create new>platform>name>create

Enable:

settings>save>confirm>enable>enable policy

Precedence order

This list represents the precedence order in which CrowdStrike applies prevention policies to a host — Default sits at the lowest precedence (a catch-all for hosts not assigned to a custom policy), while Phase 1–3 are custom policies with higher precedence, assigned to specific host groups as you progress through deployment. "Prevention Policy Precedence" is an accurate title for it.

  • Phase 3: Full standard protection
  • Phase 2: Interim protection, no AV/EDR in place
  • Phase 1: Rapid deployment, minimal protection
  • Default (lowest precedence): Out-of-box policy, applies before custom phases are set

AV = antivirus — traditional signature-based malware detection.

EDR = Endpoint Detection and Response — monitors endpoint activity in real time to detect, investigate, and respond to threats (like Falcon itself). AV mainly blocks known malware; EDR watches for suspicious behavior, including attacks AV would miss.
