Website Security Best Practices Guide

Website security protects against hacking, malware, and data breaches. This guide covers essential security measures.

Common Website Threats

• Malware: Malicious software injected into your site
• Brute Force Attacks: Automated login attempts
• SQL Injection: Database attacks via forms
• DDoS Attacks: Overwhelming traffic to crash site
• Phishing: Fake login pages to steal credentials
• Cross-Site Scripting (XSS): Code injection attacks

Essential Security Measures

1. Use Strong Passwords

• 20+ characters minimum
• Mix uppercase, lowercase, numbers, symbols
• No dictionary words
• Unique for each account
• Use password manager (1Password, LastPass)

2. Keep Software Updated

• WordPress core (update within 48 hours)
• Themes (check monthly)
• Plugins (update weekly)
• PHP version (use PHP 8.0+)
• Enable auto-updates for minor releases

3. Install SSL Certificate

• Enables HTTPS (encrypted connection)
• Required for trust and SEO
• Free with Let's Encrypt
• Force HTTPS redirect

4. Implement Firewall

• Web Application Firewall (WAF)
• Cloudflare (free plan available)
• Wordfence plugin (WordPress)
• Blocks malicious traffic

WordPress Security

Security Plugins

Wordfence Security (Recommended):

• Malware scanning
• Firewall protection
• Login security
• Two-factor authentication

Alternative Plugins:

Hardening WordPress

1. Change default login URL: Use WPS Hide Login plugin
2. Limit login attempts: Lock out after 3 failed attempts
3. Disable XML-RPC: Common attack vector
4. Disable file editing: Add to wp-config.php: define('DISALLOW_FILE_EDIT', true);
5. Change database prefix: From wp_ to something unique
6. Hide WordPress version: Remove version from meta tags

Server Security

• SSH Access: Use SSH keys instead of passwords
• Disable root login: Create sudo user instead
• Fail2Ban: Automatically ban suspicious IPs
• File Permissions: Set correctly (755 for directories, 644 for files)
• Regular Updates: Keep server OS updated

Backup Strategy

• Daily automated backups
• Store offsite (cloud storage)
• Test restores quarterly
• Keep 30 days of backups

Monitoring & Alerts

• Uptime monitoring: Get alerts when site goes down
• Malware scanning: Daily automated scans
• File change detection: Alert on unauthorized changes
• Failed login alerts: Notify on suspicious activity

Security Checklist

• ✅ Strong passwords everywhere
• ✅ Two-factor authentication enabled
• ✅ SSL certificate installed
• ✅ Firewall active
• ✅ Software updated regularly
• ✅ Daily backups
• ✅ Security plugin installed

If Your Site Gets Hacked

1. Take site offline: Maintenance mode
2. Scan for malware: Use security plugin
3. Restore from clean backup: Before hack occurred
4. Change all passwords: WordPress, hosting, database, FTP
5. Update everything: WordPress, themes, plugins
