As bookings move online, fraud and platform policy noise increase. Here's a focused security checklist for independent hosts — from anti-fraud signals to approval workflows.

Hardening Your Booking Stack: Security and Fraud Checklist for Hosts (2026)

Hook: In 2026 hostile actors target booking platforms and hosts. You don't need an enterprise security team to reduce risk — you need repeatable controls and monitoring. This checklist adapts developer-grade recommendations for the host environment.

Top threats to watch

Fraudulent bookings and chargebacks
Fake reviews and reputation attacks
Abuse of digital approvals and waivers

Operational controls

Require identity confirmation for high-value stays
Use refundable deposits for group bookings and co-living
Maintain clear incident response and cancellation policies

Technical protections

Integrate anti-fraud signals at booking time; follow best practices from the Play Store anti-fraud conversations for app makers — see Play Store Anti‑Fraud API Launches — What Test Prep App Makers Must Do (2026) for analogous technical measures.
Harden JavaScript and client-facing code if you run custom widgets — recommendations are in Hardening Your JavaScript Shop: Security Checklist.
Keep audit logs for digital code-based access (smart locks) and rotate credentials frequently.

Approvals, waivers and policy

Electronic approvals must be auditable and clear to guests. Platform policy updates around electronic approvals provide a framework hosts should replicate — see the recent update at Platform Policy Update — New Electronic Approvals Standard.

Detection and monitoring

Watch booking patterns for anomalies: high-frequency short stays, last-minute card changes, or multiple failed attempts from the same device. Set threshold alerts and have a manual review workflow.

Incident response template

Isolate the booking and block access codes
Contact the guest and payment provider
Collect logs (access events, messages) and escalate to law enforcement if fraud suspected

Training and staff practices

Train staff to recognize social engineering, enforce verification policies, and use templated escalation paths. Keep documentation handy and run quarterly tabletop exercises to validate the response.

Final checklist (action this week)

Require identity confirmation for bookings over a defined threshold
Set manual review thresholds for unusual patterns
Draft an incident response template and run a tabletop
