Website Security Guide Thailand

Security
Over 30,000 websites are hacked daily — most not targeted specifically but found by automated bots constantly scanning for vulnerabilities. Consequences include data breaches, spam distribution, and Google blacklisting your site.
Installation: SSL/HTTPS
The first security step: install an SSL Certificate and redirect all HTTP traffic to HTTPS. SSL encrypts data between users and the server, preventing Man-in-the-Middle attacks. Google Chrome marks HTTP sites as "Not Secure," destroying visitor trust.
Software
Most vulnerabilities are patched in security updates. Failing to update leaves your site with "known vulnerabilities" that bots can exploit trivially — especially WordPress core, plugins, and themes.
Password Account Management
Weak passwords are a primary cause of hacking. Use a Password Manager to generate unique 12+ character passwords combining uppercase, lowercase, numbers, and symbols for every account.
Two-Factor Authentication 2FA
2FA adds a security layer so that even knowing the password isn't enough to login — a code from an Authenticator App or SMS is also required. Enable 2FA on hosting, WordPress admin, email, and domain registrar accounts.
Backup
Backups don't prevent hacking but serve as a recovery safety net. Backup both files and database daily, store off-site in separate cloud storage. After a hack, restore from a clean backup created before the compromise.
Web Application Firewall WAF
A WAF filters incoming HTTP requests, blocking SQL Injection, XSS, CSRF, and bot attacks before they reach your application. Cloudflare's free plan includes basic WAF. Wordfence provides WordPress application-level WAF.
Malware Scanning
Regularly scan your website for malware that may be embedded without your knowledge. For WordPress: Wordfence, Sucuri, or MalCare offer free scanning. For any website: Sucuri SiteCheck or VirusTotal URL scanning.
Security Monitoring
Regular monitoring detects problems early before they cause major damage. Monitor uptime (site availability), Google Search Console (spam/malware warnings), and traffic anomalies indicating compromise.
