Cyberattacks are not just a problem for large corporations. Small and medium-sized businesses are actually targeted more frequently because their security measures tend to be weaker. If your website gets hacked, you lose customer trust, your Google ranking drops, and you may face legal issues.
43% of cyberattacks target small businesses, and 60% of those businesses close within 6 months of the attack.
1. SSL Certificate: The Fundamental Security Step
An SSL certificate encrypts the data communication between your website and its visitors. It is recognized by the lock icon and "https" in the browser address bar.
- Google marks sites without SSL as "Not Secure"
- It directly affects your SEO ranking — Google favors SSL-enabled sites
- It is legally mandatory if you conduct e-commerce
- You can get a free SSL certificate with Let's Encrypt
2. Strong Password Policy
Weak passwords are the most common security vulnerability. Passwords like "123456," "admin," and "password123" can be cracked within minutes.
- Use at least 12 characters with uppercase, lowercase, numbers, and special characters
- Set a different password for each platform
- Use a password manager (Bitwarden is free and reliable)
- Always enable two-factor authentication (2FA)
- Change default admin usernames (use something other than "admin")
3. Regular Backups
Backups save your business even in the worst-case scenario. If your site gets hacked, the server crashes, or data is accidentally deleted, you can restore from your backup.
- Set up daily automatic backups
- Store backups on a separate server or cloud storage
- Back up both files and the database
- Test backup restoration once a month
- Keep at least 30 days of backup history
4. Software Updates
WordPress, plugins, themes, and server software must be updated regularly. Updates typically patch security vulnerabilities.
- Always keep the WordPress core up to date
- Delete unused plugins and themes — each one is a potential security gap
- Enable automatic updates or establish a weekly check routine
- Always take a backup before updating
5. Web Application Firewall (WAF)
A WAF filters malicious traffic coming to your website. It provides protection against common attacks like SQL injection, XSS, and DDoS.
- Cloudflare (free plan available): Offers both CDN and WAF services
- Sucuri: Comprehensive security solution for WordPress sites
- Wordfence: Easy installation as a WordPress plugin
6. Data Privacy and Compliance
In Turkey, the protection of personal data is a legal requirement under KVKK (the Turkish Data Protection Law). Non-compliance can result in significant fines.
- Add a privacy policy and cookie notice
- Store personal data in encrypted form
- Create a data processing inventory
- Grant users the right to delete and correct their data
- Add data protection disclosure text to your website
7. Security Checklist
- Is the SSL certificate active?
- Are all passwords strong and unique?
- Is two-factor authentication enabled?
- Is automatic backup running?
- Are software and plugins up to date?
- Have unused plugins been deleted?
- Is the firewall (WAF) active?
- Is data privacy compliance ensured?
- Is there an IP restriction for admin login?
- Are file permissions set correctly?
Conclusion
Website security is not a one-time task but an ongoing process. Review the checklist above regularly. Getting professional security support will protect you from significant losses in the long run.
