Log into Falcon Console: https://falcon.crowdstrike.com\n2. Navigate: Host setup and management → Sensor downloads\n3. Download the appropriate installer:\n   - Windows: WindowsSensor_<version>.exe\n   - macOS: FalconSensorMacOS_<version>.pkg\n   - Linux: falcon-sensor_<version>_amd64.deb / .rpm\n4. Copy the Customer ID (CID) from the Sensor downloads page\n   - CID format: <32-char-hex>-<2-char-checksum>\n```\n\n### Step 2: Deploy Falcon Sensor - Windows\n\n**Silent installation via command line**:\n```cmd\nWindowsSensor_7.18.17106.exe /install /quiet /norestart CID=<YOUR_CID>\n```\n\n**SCCM deployment**:\n```\n1. Create an Application in SCCM\n2. Deployment type: Script Installer\n3. Install command: WindowsSensor_7.18.17106.exe /install /quiet /norestart CID=<CID>\n4. Detection method: Registry key exists\n   - HKLM\\SYSTEM\\CrowdStrike\\{9b03c1d9-3138-44ed-9fae-d9f4c034b88d}\\{16e0423f-7058-48c9-a204-725362b67639}\\Default\n5. Deploy to target collection\n6. Deployment purpose: Required (for mandatory installation)\n```\n\n**Microsoft Intune deployment**:\n```\n1. Navigate: Devices → Windows → Configuration profiles\n2. Create Win32 app deployment\n3. Upload .intunewin package (wrapped sensor installer)\n4. Install command: WindowsSensor_7.18.17106.exe /install /quiet /norestart CID=<CID>\n5. Detection rule: File exists C:\\Windows\\System32\\drivers\\CrowdStrike\\csagent.sys\n6. Assign to device group\n```\n\n**GPO deployment**:\n```powershell\n# Create startup script that checks for existing installation\n$sensorPath = \"C:\\Windows\\System32\\drivers\\CrowdStrike\\csagent.sys\"\nif (-not (Test-Path $sensorPath)) {\n    Start-Process -FilePath \"\\\\fileserver\\CrowdStrike\\WindowsSensor.exe\" `\n      -ArgumentList \"/install /quiet /norestart CID=<CID>\" -Wait\n}\n```\n\n### Step 3: Deploy Falcon Sensor - Linux\n\n```bash\n# Debian/Ubuntu\nsudo dpkg -i falcon-sensor_7.18.0-17106_amd64.deb\nsudo /opt/CrowdStrike/falconctl -s -f --cid=<YOUR_CID>\nsudo systemctl start falcon-sensor\nsudo systemctl enable falcon-sensor\n\n# RHEL/CentOS\nsudo yum install falcon-sensor-7.18.0-17106.el8.x86_64.rpm\nsudo /opt/CrowdStrike/falconctl -s -f --cid=<YOUR_CID>\nsudo systemctl start falcon-sensor\nsudo systemctl enable falcon-sensor\n\n# Verify sensor is running and connected\nsudo /opt/CrowdStrike/falconctl -g --rfm-state\n# Expected output: rfm-state=false (sensor is communicating with cloud)\n```\n\n### Step 4: Deploy Falcon Sensor - macOS\n\n```bash\n# Install sensor package\nsudo installer -pkg FalconSensorMacOS_7.18.pkg -target /\n\n# Set CID\nsudo /Applications/Falcon.app/Contents/Resources/falconctl license <YOUR_CID>\n\n# Grant Full Disk Access and System Extension via MDM profile\n# Required for macOS Ventura+ (manual approval or MDM PPPC profile)\n# MDM payload: com.crowdstrike.falcon.Agent → SystemExtension + Full Disk Access\n\n# Verify sensor status\nsudo /Applications/Falcon.app/Contents/Resources/falconctl stats\n```\n\n### Step 5: Configure Prevention Policies\n\nIn Falcon Console, navigate to Configuration → Prevention Policies:\n\n**Recommended prevention policy settings**:\n```\nMachine Learning:\n  - Cloud ML: Aggressive (extra protection, may increase false positives)\n  - Sensor ML: Moderate\n  - Adware & PUP: Moderate\n\nBehavioral Protection:\n  - On Write: Enabled (detect malware on file creation)\n  - On Sensor ML: Enabled\n  - Interpreter-Only: Enabled (detect script-based attacks)\n\nExploit Mitigation:\n  - Exploit behavior protection: Enabled\n  - Memory scanning: Enabled (detects in-memory attacks)\n  - Code injection: Enabled\n\nRansomware:\n  - Ransomware protection: Enabled\n  - Shadow copy protection: Enabled\n  - MBR protection: Enabled\n```\n\n**Create separate policies for**:\n- Workstations (aggressive settings)\n- Servers (moderate settings to avoid false positives on server workloads)\n- Critical infrastructure (maximum protection with exception lists)\n\n### Step 6: Configure Response Policies\n\n```\nReal-Time Response:\n  - Enable RTR for all sensor groups\n  - Configure RTR admin vs. RTR responder roles\n  - Enable script execution (for IR teams)\n  - Enable file extraction (for forensics)\n\nNetwork Containment:\n  - Pre-authorize containment for specific host groups\n  - Configure containment exclusions (allow management traffic)\n\nAutomated Response:\n  - Enable automated remediation for high-confidence detections\n  - Configure kill process action for ransomware detections\n  - Enable quarantine for malware file detections\n```\n\n### Step 7: Validate Deployment\n\n```powershell\n# Windows: Check Falcon sensor status\nsc query csagent\n# Expected: RUNNING\n\n# Check sensor version\nreg query \"HKLM\\SYSTEM\\CrowdStrike\\{9b03c1d9-3138-44ed-9fae-d9f4c034b88d}\\{16e0423f-7058-48c9-a204-725362b67639}\\Default\" /v AgentVersion\n\n# Verify cloud connectivity\n# In Falcon Console: Host Management → Hosts → search for hostname\n# Status should show \"Online\" with last seen timestamp < 5 minutes\n```\n\n**Test detection capability**:\n```powershell\n# CrowdStrike provides test detection samples\n# Download CsTestDetect.exe from Falcon Console → Host setup\n# Run on endpoint to generate a test detection\n.\\CsTestDetect.exe\n# Verify detection appears in Falcon Console within 60 seconds\n```\n\n### Step 8: SIEM Integration\n\n```\n# Falcon SIEM Connector (Streaming API)\n# Configure in Falcon Console: Support → API Clients and Keys\n\n# Create API client with scope: Event Streams → Read\n# Use falcon-siem-connector or Falcon Data Replicator (FDR)\n\n# Splunk integration:\n# Install CrowdStrike Falcon Event Streams Technical Add-on from Splunkbase\n# Configure: Settings → Data inputs → CrowdStrike Falcon Event Streams\n# Enter API Client ID and Secret\n# Index: crowdstrike_events\n\n# Elastic integration:\n# Use Elastic Agent with CrowdStrike module\n# Configure: Fleet → Agent policies → Add integration → CrowdStrike\n```\n\n## Key Concepts\n\n| Term | Definition |\n|------|-----------|\n| **Falcon Sensor** | Lightweight kernel-mode agent (25-30 MB) that collects endpoint telemetry and enforces prevention policies |\n| **CID (Customer ID)** | Unique identifier that associates the sensor with your CrowdStrike Falcon tenant |\n| **RFM (Reduced Functionality Mode)** | State where sensor operates with limited capability due to cloud connectivity loss |\n| **Sensor Grouping Tags** | Labels applied during installation to auto-assign hosts to groups and policies |\n| **RTR (Real-Time Response)** | Remote shell capability for incident responders to interact with endpoints through Falcon |\n| **IOA (Indicators of Attack)** | Behavioral detections based on adversary techniques rather than static signatures |\n\n## Tools & Systems\n\n- **CrowdStrike Falcon Console**: Cloud-hosted management platform for all Falcon modules\n- **Falcon SIEM Connector**: Streams detection and audit events to SIEM platforms\n- **Falcon Data Replicator (FDR)**: Streams raw endpoint telemetry to S3/cloud storage for hunting\n- **CrowdStrike Falcon API (OAuth2)**: RESTful API for automation, integration, and custom workflows\n- **PSFalcon**: PowerShell module for CrowdStrike Falcon API automation\n\n## Common Pitfalls\n\n- **Missing CID during installation**: Sensor installs but never connects to Falcon cloud. Always pass CID during install, not after.\n- **Proxy not configured**: In environments with web proxies, configure proxy during installation: `/install /quiet CID=<CID> APP_PROXYNAME=proxy.corp.com APP_PROXYPORT=8080`.\n- **macOS System Extension blocked**: macOS requires explicit approval for kernel/system extensions. Use MDM to pre-approve CrowdStrike extensions before deployment.\n- **Conflicting security products**: Running multiple EDR/AV products causes performance issues and false positives. Coordinate exclusions or remove legacy AV before Falcon deployment.\n- **Sensor version pinning**: Falcon auto-updates sensors by default. Pin sensor versions in the console for change-controlled environments before testing new versions.\n\n## Other files in this skill\n\n-
