Website Security Checklist: Essential Steps for Your Online Presence
When your website doesn’t feel safe, neither do your visitors — and that has direct consequences for trust, conversions, and even search rankings. This checklist outlines ten practical steps to help small- and medium-sized businesses secure their websites and maintain a strong web presence. (Based on leading best practices)
1. Prevent Spam
Spam isn’t just annoying — it can hurt your site’s quality signals and create vulnerabilities. Use CAPTCHAs or honeypots to block bots submitting forms or posting comments.
Checklist items:
- Enable CAPTCHA or honeypot on contact forms
- Moderate comments or user-generated content
- Monitor for bulk spam submissions
2. Protect Against DDoS Attacks
A DDoS (distributed denial of service) attack can flood your website with fake traffic, slow it down or even crash it — which disrupts service and damages visitor trust.
Checklist items:
- Choose a hosting provider with DDoS protection and WAF (Web Application Firewall)
- Use load-balancers or traffic filtering tools
- Monitor unusual traffic patterns
3. Block Brute-Force Attacks
Hackers may attempt to guess login credentials by forcing repeated attempts. Protect your admin area or login pages accordingly.
Checklist items:
- Enforce strong password policies (upper/lower case, numbers, special characters)
- Limit failed login attempts or introduce lockouts
- Enable two-factor authentication (2FA) on admin accounts
4. Safeguard Against Cross-Site Scripting (XSS)
XSS attacks allow malicious scripts to run in your visitors’ browsers, which can compromise data and damage reputation.
Checklist items:
- Implement a Content Security Policy (CSP) to control what scripts can run
- Sanitize any user-input or external content embedded on your pages
- Regularly audit custom code or third-party scripts
5. Beware of SQL Injection
SQL injection attacks exploit input fields to run unwanted commands on your database — exposing or corrupting your data.
Checklist items:
- Use parameterised queries so input is treated as data, not code
- Audit database access logs for suspicious activity
- Limit database user permissions to only what’s necessary
6. Install an SSL Certificate (HTTPS)
Encryption matters. An SSL certificate ensures data between your visitor’s browser and your server is private and secure — and displays the padlock icon that builds trust.
Checklist items:
- Ensure your site uses HTTPS (not HTTP) site-wide
- Renew your certificate before expiry
- Check for mixed content warnings (HTTP assets on HTTPS page)
7. Back Up Website Data
Whether due to a hack, human error or technical failure, data loss is real. Regular backups mean you can restore quickly and minimise damage.
Checklist items:
- Enable automatic backups via hosting or third-party service
- Store backups off-site (or separate from main server)
- Test restores periodically to ensure backups work
8. Follow Data Security Standards (like ISO 27018)
If your website handles personal data — especially in regulated industries — compliance and standards become important. For instance, ISO 27018 covers cloud privacy protection.
Checklist items:
- Determine what standards apply to your business (GDPR, PCI, HIPAA, etc.)
- Document your data-handling practices
- Audit your hosting provider’s certifications and compliance
9. Use Reliable Payment Gateways
If you accept payments, don’t roll your own solution unless you have deep expertise. Use established gateways that comply with payment data standards (PCI DSS) so your customers’ financial data stays safe.
Checklist items:
- Integrate trusted third-party payment processors (e.g., Stripe, PayPal)
- Ensure PCI-DSS compliance if handling card data
- Regularly test and audit your payment flow for vulnerabilities
10. Regularly Update Your Website
Out-of-date software (CMS, plugins, themes) is one of the most common ways attackers get into websites. Staying current is non-negotiable.
Checklist items:
- Check for and install updates on your CMS or site platform
- Remove or disable unused plugins/modules/themes
- Schedule periodic security scans and vulnerability checks
