Key Features for Cursor Security

1. Process Execution Monitoring

What It Detects:

  • Suspicious child process spawning
  • Unusual command-line arguments
  • Malicious script execution
  • Unauthorized elevation attempts

Example: Protecting Against Malicious npm Package:

1
2
3
4
5
6
7
8
9
10

Detection Timeline:
1. Developer runs: npm install malicious-package
2. Package postinstall script executes
3. Script attempts to:
   - Read SSH keys from ~/.ssh
   - Connect to external C2 server
   - Encrypt documents folder
4. CrowdStrike blocks all three actions
5. Alert sent to security team
6. Package quarantined

2. Network Connection Monitoring

Capabilities:

  • Track all outbound connections
  • Detect C2 (command & control) beacons
  • Identify data exfiltration attempts
  • Block malicious domains

# Falcon policy: Developer Workstations
prevention_policy:
  name: "Cursor-Developer-Policy"
  exclusions:
    processes:
      - path: "/Applications/Cursor.app"
      - path: "*/node_modules/*"
      - path: "*/npm-cache/*"
    directories:
      - "~/workspace/*"  # Monitored but not blocked
      - "~/dev/*"
  monitoring:
    log_all: true  # Still log everything
    block_suspicious: true  # But don't block normal dev activity

2. Enable SIEM Integration

Send Detections to Chronicle:

# Configure CrowdStrike Event Stream API
curl -X POST "https://api.crowdstrike.com/sensors/entities/datafeed/v2" \
  -H "Authorization: Bearer $FALCON_API_TOKEN" \
  -d '{
    "appId": "cribl-integration",
    "eventType": "DetectionSummaryEvent",
    "endpoint": "https://eventhub.azure.com/falcon-detections"
  }'

# Cribl routes to Chronicle for correlation

3. Configure USB Control

Balance Security & Usability:

1
2

Allow: Company-issued USB-C hubs, keyboards, mice
Block: USB storage devices
Require: Manager approval for exceptions
Audit: All USB device connections logged

4. Set Up Response Playbooks

# Example: Auto-response to credential theft attempt

def handle_credential_theft_alert(alert):
    user_id = alert['user_id']
    hostname = alert['hostname']
    
    # 1. Isolate host from network (via Falcon API)
    falcon.isolate_host(hostname)
    
    # 2. Force Azure/Okta session logout
    okta.revoke_user_sessions(user_id)
    azure.revoke_refresh_tokens(user_id)
    
    # 3. Notify security team
    teams.send_alert(channel='security-incidents', alert=alert)
    
    # 4. Create incident ticket
    jira.create_incident(alert)
    
    # 5. Require password reset
    okta.require_password_reset(user_id)

Integration with Other Tools

CrowdStrike + Wiz

Complementary Coverage:

  • CrowdStrike: Endpoint/workstation security
  • Wiz: Cloud infrastructure security

Shared Intelligence:

Threat Scenario:
1. Wiz detects misconfigured Azure OpenAI (public access)
2. Attacker exploits misconfiguration
3. CrowdStrike detects unusual API activity from developer workstation
4. Correlation in Chronicle: Same attack campaign
5. Unified response: Fix cloud config + isolate endpoint

CrowdStrike + Okta

CrowdStrike sends to SIEM:

├── Local User: john.developer
├── Process: suspicious-script.exe
└── Okta enrichment:

    ├── Manager: jane.manager@company.com
    ├── Department: Engineering
    ├── Last Login: 2 hours ago
    └── Risk Score: 85/100 (recent password change)

Why Not Palo Alto Cortex XDR?

As mentioned in the overview, the customer chose CrowdStrike over Cortex XDR:

CrowdStrike Advantages:

  1. Better endpoint protection: More mature EDR platform
  2. Lighter agent: Lower performance impact
  3. Cloud-native: No on-prem infrastructure
  4. Threat intelligence: Industry-leading intel from CrowdStrike team
  5. Established deployment: Already in use, proven at scale

Cortex XDR Would Add:

  • ❌ Duplicate endpoint protection (overlaps CrowdStrike)
  • ❌ Additional agent overhead
  • ❌ Migration cost and risk
  • ❌ Team retraining required
