How to save your website from hackers, illegal activites

1. Secure the Technical Foundation

These are non-negotiable basics.

• Use HTTPS (SSL/TLS) to encrypt data in transit

• Keep software updated (CMS, plugins, frameworks, server OS)

• Strong authentication

  • Enforce strong passwords

  • Enable 2FA for admins and users

• Limit access

  • Principle of least privilege

  • Separate admin accounts from normal users

2. Protect Against Common Attacks

Most illegal activity exploits predictable weaknesses.

• Web Application Firewall (WAF)

  • Blocks SQL injection, XSS, bot attacks

• DDoS protection

  • Use services like Cloudflare, AWS Shield, etc.

• Rate limiting

  • Prevent brute-force and spam attacks

• CAPTCHA

  • On forms, logins, and registrations
    
    

    3. Secure User Data & Privacy

    Illegal activity often targets data.

    • Encrypt sensitive data at rest and in backups

    • Collect only necessary data

    • Follow privacy laws

      • GDPR, CCPA, etc. (depending on your audience)

    • Have a clear Privacy Policy

    • Never store passwords in plain text (use hashing like bcrypt)

    
    

    4. Monitor & Detect Suspicious Activity

    Early detection limits damage.

    • Enable logging

      • Login attempts

      • File changes

      • Admin actions

    • Use intrusion detection tools

    • Set alerts for unusual behavior

    • Audit logs regularly

    
    

    5. Prevent Illegal Content & Abuse

    If users can post content or interact:

    • Content moderation

      • Automated filters + manual review

    • Clear Terms of Service

      • Explicitly ban illegal activities

    • Reporting mechanisms

      • Let users flag abuse or illegal content

    • Suspend or ban offenders quickly

    
    

    6. Backup & Recovery Plan

    If something goes wrong, recovery matters.

    • Automatic, regular backups

    • Store backups off-site

    • Test recovery procedures

    • Have an incident response plan
