Your hotel website is the first place your guests see you and the platform where they share payment information with confidence. According to the IBM Cost Report published in 2025, the average cost of a data breach has reached $4.88 million; in the hospitality sector, this figure is even higher because attacks usually result in both financial and reputational loss.
If you apply this checklist regularly every 3 months, your chances of closing security vulnerabilities before attackers discover them will increase significantly. The list includes 5 categories and a total of 25 critical checkpoints.
Why a Security Checklist?
Many hotels only take cybersecurity seriously after experiencing a major attack or data breach. However, more than 84% of security vulnerabilities stem from basic flaws caused by configuration errors and neglect. A systemic checklist is the most cost-effective method for closing these gaps.
Based on OWASP and NIST standards, this list summarizes the most critical points we have extracted from security audits of more than 500 hotel businesses.
Domain and DNS Security
- Is domain lock enabled? Activate the "domain lock" or "transfer lock" feature at your registrar. Without this feature, your domain can be transferred without permission.
2. Is DNSSEC configuration correct? DNSSEC must be enabled and DNS records must be regularly signed to prevent DNS spoofing. You can use the Google DNS toolbox for verification.
3. Are unregistered similar domains being monitored? Use a monitoring service like RuuSafe Domain Scanner to receive instant alerts when a domain similar to your brand is registered. See our related guide for detailed information about Typosquatting attacks.
4. Have NS and MX records been changed without authorization? Check your DNS records every month and initiate an immediate investigation if there are unexpected changes.
5. Is your domain renewal date being tracked? If auto-renewal is not active, add the domain expiration date to your calendar. Expired domains can be seized by malicious actors within hours.
SSL/TLS Certificate Check
6. Where is the certificate validity date? Track the certificate expiration date via RuuSafe SSL Checker or Google Search Console. Start renewal at least 30 days before the certificate expires.
7. Is TLS 1.2 or 1.3 mandatory? SSL 3.0, TLS 1.0, and TLS 1.1 protocols are considered insecure. Verify that your server configuration only supports TLS 1.2+.
8. Does the certificate type match your business information? EV (Extended Validation) or OV (Organization Validated) certificates provide a stronger trust signal to your guests. DV (Domain Validated) certificates can also be easily obtained by fake sites. See our guide to detecting fake SSL certificates.
9. Is HSTS (HTTP Strict Transport Security) enabled? HSTS forces browsers to always load your site via HTTPS and prevents SSL stripping attacks.
10. Are Certificate Transparency Logs being monitored? Set up crt.sh monitoring to receive alerts when an unauthorized SSL certificate is issued in your brand's name. This allows you to detect fake sites during the certificate acquisition phase.
Web Application Security
11. Are CMS and plugins up to date? If you use WordPress, Drupal, or another CMS, make sure the core system and all plugins are on the current version. 56% of attacks exploit outdated plugins.
12. Is the admin panel URL standard? Standard URLs like /wp-admin or /admin are targets for automated attacks. Move the admin panel to a custom URL and add IP restrictions.
13. Is a WAF (Web Application Firewall) active? Cloudflare, Sucuri, or a similar WAF service provides basic protection against XSS, SQLi, and DDoS attacks.
14. Is the backup system working? A daily automatic backup and 30-day backup retention policy should be applied. Backups should be stored in a location physically separate from the site server.
15. Are HTTP security headers configured? Check Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy headers. You can use securityheaders.com to test security headers for free.
Employee Training
16. Has a phishing simulation been done in the last 6 months? 30% of employees are seen clicking in the first phishing test. Simulation tests should be applied at least twice a year.
17. Is there a strong password policy? A minimum of 12 characters, upper/lower case + number + special character requirement, along with an automatic password change reminder, should be active.
18. Is two-factor authentication (2FA) mandatory? 2FA must be enabled on all critical accounts such as email, social media, and reservation systems. SMS-based 2FA is the minimum acceptable; app-based 2FA (Google Authenticator, Authy) is more secure.
19. Are exit procedures defined? All account access of an employee leaving the job must be canceled on the day of departure. Ensure this process is coordinated by HR and IT.
20. Is the security incident reporting procedure known? All employees should know to whom and how to report a suspicious email, link, or system behavior.
Monitoring and Early Warning
21. Is uptime monitoring active? An uptime monitor (Uptime Robot, Pingdom, etc.) that detects site outages within 5 minutes must be used.
22. Is fake site monitoring being done? A system should be established that monitors the registration of domains similar to your brand or the copying of your content in real-time.
23. Are Google search alerts set? Set up weekly notifications for your brand name via Google Alerts. Follow manual search security alerts with Google Search Console.
24. Is log analysis being done? Server logs should be kept for at least 90 days, and abnormal access patterns (bot traffic, suspicious IP blocks, failed login attempts at short intervals) should trigger automatic alerts.
25. Is there a penetration test (pentest) program? A comprehensive penetration test should be performed at least once a year. If the budget is limited, automatic scanning can be done with free tools like OWASP ZAP.
Annual Security Calendar
January: Renew all passwords, check 2FA status. March: Have a pentest or security scan done. April: Employee phishing simulation. June: Follow up on SSL certificates and domain renewals. August: DNS and DNSSEC configuration check. October: CMS and plugin updates, backup test. November: Annual cybersecurity training. December: Updating security policies.
Automated Monitoring with RuuSafe
Manual tracking of these 25 items is both time-consuming and prone to human error. RuuSafe combines fake domain monitoring, SSL certificate tracking, Certificate Transparency Logs monitoring, and automated warning systems on a single platform. It also provides comprehensive monitoring for subdomain security.
Frequently Asked Questions
How often should the checklist be applied?
Critical items (SSL date, domain lock, 2FA) should be checked monthly. The full list should be applied every 3 months and repeated completely after major system updates.
Which items are neglected the most?
In our audits, the items most frequently neglected stand out as: Certificate Transparency Logs monitoring, HTTP security headers, and exit procedures.
What is the priority order for small hotels?
Domain lock, SSL renewal calendar, 2FA, and employee phishing training—these four items form the minimum security bar and can be applied at low cost.
Conclusion
Hotel website security is not a one-time task but a process that needs to be managed continuously. Integrate this 25-item checklist into your calendar and record your findings after each audit.
