Website Security: Protect Your Site from Getting Hacked

A cyberattack occurs every 39 seconds. 43% of small businesses are targeted by cyberattacks, and 60% of those close within 6 months after an attack. Website security is critical for your business survival.

Why Do Hackers Target Websites?

  • Personal data — Customer information, emails, passwords
  • Payment info — Credit card numbers
  • SEO spam — Inject malicious links into your site
  • Botnet — Use your site for DDoS attacks
  • Ransom — Lock your site and demand payment
  • Competitor sabotage — Take your site offline

Essential Security Measures

1. SSL Certificate (HTTPS)

SSL encrypts data between your website and visitors.

Why it's mandatory:

  • Google marks non-HTTPS sites as "Not Secure"
  • SEO ranking factor
  • Builds user trust
  • Prevents data interception

How to get it:

  • Let's Encrypt — Free SSL
  • Cloudflare — Free SSL + CDN
  • Your hosting provider — Most offer built-in SSL

2. Strong Password Policy

  • Minimum 12 characters
  • Uppercase, lowercase, numbers, special characters
  • Two-factor authentication (2FA)
  • Use a password manager
  • Change default passwords

3. Regular Updates

  • CMS updates (WordPress, Drupal)
  • Plugin/theme updates
  • Server software updates
  • Framework updates
  • Security patches

4. Backup Strategy

  • Automatic daily backups
  • Store backups in a separate location
  • Test restoration from backups
  • Back up both files and databases

Common Attack Types and Prevention

SQL Injection

Injecting malicious code into database queries.

Prevention:

  • Use parameterized queries
  • Use an ORM
  • Sanitize user inputs

XSS (Cross-Site Scripting)

Injecting malicious JavaScript into web pages.

Prevention:

  • Encode user inputs
  • Content Security Policy (CSP) headers
  • HttpOnly cookie flags

DDoS Attack

Overwhelming your site with excessive traffic.

Prevention:

  • Use a CDN (Cloudflare)
  • Implement rate limiting
  • Web Application Firewall (WAF)

Brute Force

Cracking passwords through trial and error.

Prevention:

  • Account lockout mechanism
  • Rate limiting
  • CAPTCHA
  • Two-factor authentication

Security Checklist

Basic (Required for Everyone):

  • SSL certificate active
  • Strong admin password
  • Regular backups
  • Software updates
  • File permissions properly configured

Intermediate:

  • Web Application Firewall
  • Two-factor authentication
  • Security scanning tools
  • Access log monitoring
  • Rate limiting

Advanced:

  • Penetration testing
  • Intrusion detection system
  • Security headers fully configured
  • Zero trust architecture
  • Incident response plan

Security Tools

| Tool | Use | Price | |------|-----|-------| | Cloudflare | CDN + WAF + DDoS protection | Free tier | | Sucuri | Malware scanning + WAF | Paid | | Wordfence | WordPress security | Freemium | | Let's Encrypt | Free SSL | Free | | OWASP ZAP | Security scanning | Free |

Conclusion

Website security isn't a "nice to have" — it's mandatory. An attack can destroy years of work in minutes. Investing in security from the start is far cheaper than crisis management later.
