10 Website Security Best Practices Every Site Owner Should Know
Introduction
Website security is not something you can afford to ignore. Cyberattacks are increasing in both frequency and sophistication, and small to mid-sized websites are frequent targets because attackers assume they have weaker defences. A single breach can compromise customer data, destroy your reputation, and cost thousands in recovery. The good news is that most attacks are preventable with straightforward security practices. Here are ten essential steps every website owner should implement to keep their site safe.
1. 1. Use HTTPS Everywhere
An SSL certificate encrypts data transmitted between your website and your visitors, preventing attackers from intercepting sensitive information like login credentials, personal details, and payment data. HTTPS is no longer optional. Search engines penalise non-HTTPS sites in rankings, and modern browsers display prominent "Not Secure" warnings that drive visitors away.
Ensure HTTPS is enforced across every page of your site, not just login or checkout pages. Set up 301 redirects from HTTP to HTTPS and enable HTTP Strict Transport Security headers to prevent protocol downgrade attacks. BearHost includes free SSL certificates with automatic installation and renewal on every hosting plan.
2. 2. Enforce Strong Passwords and Two-Factor Authentication
Weak passwords remain one of the most common entry points for attackers. Require passwords that are at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special characters. Avoid common words, personal information, and reused passwords from other accounts.
Two-factor authentication adds a critical second layer of security. Even if an attacker obtains a password, they cannot access the account without the second factor, typically a code generated by an authenticator app or sent via SMS. Enable two-factor authentication on your hosting control panel, CMS admin area, and any connected services.
3. 3. Keep All Software Updated
Outdated software is the single largest vulnerability on most websites. Content management systems like WordPress, plugins, themes, and server software all receive regular security patches. When you delay updates, you leave known vulnerabilities open for attackers to exploit.
Enable automatic updates where possible. For WordPress sites, enable auto-updates for core, plugins, and themes. Check for updates at least weekly for any software that does not update automatically. BearHost keeps server-level software patched and up to date, but application-level updates are your responsibility.
4. 4. Deploy a Web Application Firewall
A Web Application Firewall, commonly called a WAF, filters and monitors HTTP traffic between your website and the internet. It blocks common attack patterns including SQL injection, cross-site scripting, and brute-force login attempts before they reach your server.
Cloud-based WAF services like Cloudflare or Sucuri are easy to set up and provide strong protection without modifying your server configuration. Server-level firewalls like ModSecurity add another layer of defence. BearHost includes ModSecurity on all hosting plans and offers easy Cloudflare integration for additional protection.
5. 5. Perform Regular Backups
Backups are your safety net when everything else fails. If your site is hacked, corrupted, or accidentally damaged, a recent backup lets you restore it quickly without losing data. Without backups, a security incident can mean rebuilding your entire website from scratch.
Follow the 3-2-1 backup rule: keep at least three copies of your data, on two different storage types, with one copy stored offsite. Automate your backups so they happen daily without requiring manual action. BearHost provides automated daily backups with easy one-click restoration, ensuring your data is always protected.
6. 6. Monitor for Malware and Suspicious Activity
Malware can infect your website silently, redirecting visitors to malicious sites, injecting spam content, or stealing customer data without your knowledge. Regular malware scanning detects infections early so you can remove them before they cause significant damage.
Set up monitoring tools that scan your site files and database for known malware signatures and suspicious code patterns. Review your server access logs periodically for unusual activity such as repeated failed login attempts, unexpected file changes, or traffic from suspicious IP addresses. BearHost includes malware scanning and server-level monitoring to help detect threats proactively.
7. 7. Limit User Permissions and Secure File Uploads
Follow the principle of least privilege. Every user account on your website should have only the permissions necessary for their role. Administrators need full access, but editors, authors, and contributors should have restricted capabilities. If an account with limited permissions is compromised, the damage an attacker can do is significantly reduced.
File upload functionality is a common attack vector. If your site accepts file uploads, restrict allowed file types to only what is necessary, scan uploaded files for malware, limit file sizes, and store uploads outside the web root directory when possible. Never allow executable file types like PHP, EXE, or JS to be uploaded through public-facing forms.
8. 8. Implement Security Headers
HTTP security headers instruct browsers on how to handle your site content, preventing many common attack types. Content-Security-Policy headers prevent cross-site scripting by controlling which resources the browser is allowed to load. X-Frame-Options prevents clickjacking by blocking your site from being embedded in iframes on other domains.
Additional important headers include X-Content-Type-Options to prevent MIME-type sniffing, Referrer-Policy to control information shared when users navigate away, and Permissions-Policy to restrict browser features like camera or microphone access. These headers are easy to implement through your server configuration or hosting control panel.
9. 9. Choose Secure Hosting
Your hosting provider is the foundation of your website security. A poorly secured server undermines every other security measure you implement. Choose a hosting provider that takes security seriously with features like server-level firewalls, intrusion detection systems, DDoS protection, regular security patching, and isolated hosting environments.
Look for providers that include free SSL certificates, automated backups, malware scanning, and proactive server monitoring. BearHost builds security into every hosting plan with ModSecurity firewalls, free SSL, daily automated backups, malware scanning, and 24/7 server monitoring. Choosing secure hosting is the single most impactful security decision you can make.
10. 10. Create a Security Response Plan
Despite your best efforts, no security is absolute. Having a documented response plan ensures you can act quickly and effectively if a breach occurs. Your plan should include steps for identifying the breach, isolating affected systems, removing the threat, restoring from backups, notifying affected users, and strengthening defences to prevent recurrence.
Test your response plan regularly. Verify that your backups actually restore correctly. Ensure your team knows who is responsible for each step. The difference between a minor incident and a catastrophic breach often comes down to how quickly and effectively you respond.
Conclusion
Website security is an ongoing responsibility, not a one-time setup. By implementing these ten best practices, you dramatically reduce your risk of falling victim to cyberattacks. Start with the basics like HTTPS, strong passwords, and regular updates, then build additional layers of defence over time. BearHost supports your security efforts with built-in SSL certificates, automated backups, malware scanning, ModSecurity firewalls, and expert support. Protect your website, your visitors, and your business by making security a priority today.
