Cars need regular maintenance; websites are no different. After launch, continuous checks are required, otherwise vulnerabilities may silently expand and cause irreparable losses.
Many SMEs mistakenly believe their small scale avoids targeting, yet over 40% of attacks focus on such sites due to lack of regular maintenance. Common cases include redirects to gambling pages or phishing emails, all stemming from missing basic protections.
This list organizes 10 key checkpoints for systematic website security maintenance.
Items 1-3: Certificate, Updates and Password
These three form the most basic defense line yet are often overlooked.
Item 1: SSL Certificate
The certificate encrypts transmissions; expiration triggers browser warnings and most visitors leave immediately.
Key checks:
- Is the certificate still valid (detectable via online tools)
- Does HTTP auto-redirect to HTTPS
- Any mixed content on pages
- Auto-renewal enabled
Refer to the HTTPS complete guide for deeper understanding.
Item 2: Software Updates
Outdated versions are common hacker entry points; updates deliver patches that reduce risks.
Key checks:
- Is the core system the latest version
- Are plugins and packages updated
- Remove unused plugins
- Are server software versions still supported
Reminder: Always back up before updating to avoid unrecoverable theme damage.
Item 3: Password Strength
Weak passwords are easily brute-forced; use combinations of at least 12 characters with mixed types.
Key checks:
- Admin passwords at least 12 characters including case, numbers and symbols
- Avoid common weak passwords
- Use different passwords across platforms
- Change every 90 days and employ a password manager
Items 4-6: Backup, Permissions and Login
These three act as insurance mechanisms to minimize losses during attacks.
Item 4: Backup Mechanism
Backup is the final line of defense; confirm it includes database and files and test restoration regularly.
Key checks:
- Daily auto-backup functioning
- Content complete
- Offsite backup available
- Regular restoration tests
- Keep 7-30 days of history
Refer to the website maintenance guide.
Item 5: File Permissions
Overly permissive settings invite malware injection.
Key checks:
- Directories 755, files 644
- Config files 600
- Upload directory blocks PHP execution
- No 777 permissions anywhere
Item 6: Login Security
Strengthening login blocks most brute-force attempts.
Key checks:
- Enable two-factor authentication
- Set login failure lockouts
- Change default admin path
- Restrict access to specific IPs
Changing the path and enabling 2FA alone blocks over 90% of automated attacks.
Items 7-10: Scanning, Forms, Errors and Logs
These four belong to detection and monitoring, enabling early anomaly discovery.
Item 7: Malware Scanning
Regular scans ensure the site stays clean.
Key checks:
- Use scanning tools periodically
- Check for malware flags by search engines
- Confirm absence from blacklists
- Verify core files have not been altered
Item 8: Form Protection
Forms are common attack vectors.
Key checks:
- Add CAPTCHA
- Backend filters all input
- Use parameterized queries against SQL injection
- Limit submission frequency
Read the website security essentials guide.
Item 9: Error Page Handling
Default error pages leak server information.
Key checks:
- Disable debug mode in production
- Customize error pages
- Hide server version info
- Keep messages user-friendly
Item 10: Access Log Monitoring
Logs reveal suspicious activity.
Key checks:
- Regularly review access and error logs
- Monitor abnormal IP requests
- Record admin operations
- Set anomaly notifications
Establish a Regular Audit Schedule
Consistent execution is key; allocate items by risk level.
| Frequency | Items |
|---|---|
| Weekly | Backup verification, access log review, site operation check |
| Monthly | SSL certificate, software updates, malware scan, offsite backup restoration test |
| Quarterly | Password rotation, file permission audit, account permission review |
| Yearly | Full security audit, penetration test, disaster recovery drill |
Practical tips:
- Set recurring reminders
- Maintain a spreadsheet for results
- Assign a responsible person
Self-Check vs Professional Audit
Most items can be done internally; deeper assessments should be outsourced.
Suitable for self-check:
- SSL certificate validity
- Password strength and rotation
- Backup verification
- Software version updates
- Basic access log review
Recommended for professional handling:
- Penetration testing
- Source code security audit
- Server security configuration optimization
- Security policy and compliance assessment
- Incident response plan creation
If the site was previously compromised, refer to the hacked-site response guide.
Choosing a security-focused corporate website builder reduces risks from the outset.
Conclusion: Cultivate Security Audit Habits to Prevent Issues
Security audits must be ongoing; start with weekly backup checks and monthly SSL updates. Prevention is always cheaper than remediation.
