Welcome to the exciting world of web development! You’ve written your first lines of code, chosen a hosting provider, and deployed your creation for the world to see. Congratulations! But now that your website is live, there’s a crucial aspect you absolutely cannot ignore, even as a beginner: security.
Securing your hosted website might sound intimidating, but it’s an essential practice to protect your hard work, your visitors, and your reputation. Think of these basic security tips for your hosted website as building a strong foundation – they are fundamental steps every beginner coder should take.
Ignoring security can lead to data breaches, website defacement, loss of data, and even your hosting account being suspended. Fortunately, implementing core security principles is manageable, even without advanced cybersecurity knowledge. Based on best practices, here’s a guide to get you started.
Layer Up Your Defenses: Core Security Principles
Effective website security isn’t about one single solution; it’s a multi-layered approach. By addressing security at different points, you significantly reduce the risk of an attack.
1. Strengthen Authentication and Access Control
This is often the first line of defense. Weak passwords are easy targets.
- Change Default Passwords: If your hosting provider, CMS (like WordPress), or any service came with default credentials, change them IMMEDIATELY. Attackers know these defaults and will try them first.
- Use Strong, Unique Passwords: Create complex passwords using a mix of uppercase and lowercase letters, numbers, and symbols. Never reuse passwords across different services. Consider using a password manager.
- Enable Two-Factor Authentication (2FA): Whenever possible, enable 2FA for your hosting control panel, CMS admin area, and any other critical service. This requires a second form of verification (like a code from your phone) in addition to your password.
- Limit User Permissions: If others have access to your website or hosting account, grant them only the necessary permissions. Don’t give administrator access to everyone.

2. Secure Data Transmission with HTTPS
When users visit your website, information is exchanged between their browser and your server. If this information isn’t encrypted, it can be intercepted.
- Install SSL/TLS Certificates (Use HTTPS): An SSL/TLS certificate encrypts the connection between the user’s browser and your server. This is why you see “HTTPS” and a padlock in the browser’s address bar. Most hosting providers offer free SSL certificates (like Let’s Encrypt). Using HTTPS is non-negotiable for protecting sensitive data like login credentials or form submissions, and it’s also a ranking factor for search engines.

- Use Secure Protocols: When uploading files, use SFTP (SSH File Transfer Protocol) instead of plain FTP. SFTP encrypts your login credentials and data transfer.
3. Keep Everything Up-to-Date
Software vulnerabilities are common, but vendors release updates to fix them. Running outdated software is like leaving the back door open.
- Regularly Update Software: This includes your server’s operating system (though often handled by the host on shared plans), your web server software (Apache, Nginx), your CMS (WordPress, Joomla, etc.), themes, and plugins/extensions. Set up automatic updates where appropriate, but monitor them.
- Change CMS Default Settings: Don’t leave your CMS configured exactly as it was installed. Change default admin usernames, database prefixes, and directory names if your CMS allows.
4. Implement Application and Network Protection
While your hosting provider handles some network-level security, there are steps you can take for your specific website.
- Web Application Firewall (WAF): A WAF filters malicious traffic before it reaches your website application. Some hosting providers offer WAFs, or you can use third-party services.
- Understand Input Validation: As a beginner coder, this is critical. Input validation is the practice of ensuring user-provided data is clean, correct, and useful. Never trust user input directly. Sanitize and escape all data submitted through forms, URLs, or any other input method to prevent injection attacks (like SQL injection or Cross-Site Scripting – XSS). Don’t allow user input to be executed as code on your server. This is a fundamental coding security principle.
- Basic DDoS Protection: While large-scale DDoS attacks require specialized services, some basic rate limiting or firewall rules can help mitigate smaller attacks. Your hosting provider likely has some level of DDoS protection.

5. Don’t Skip Backups!
Even with the best security, things can go wrong. Backups are your lifeline.
- Regularly Back-Up Data: Set up automated, frequent backups of your website files and databases. Check that these backups are running successfully.
- Store Backups Securely and Remotely: Don’t just store backups on the same server as your website. Download them or store them in a separate cloud storage service. This ensures you can restore your site even if the main server is compromised or unavailable.
6. Minimize Your Attack Surface
The fewer points of entry attackers have, the safer your site is.
- Don’t Expose Unnecessary Services: Close unused ports and disable unnecessary services running on your server (if you have that level of control).
- Choose a Secure Hosting Provider: If you’re using shared hosting, the provider is responsible for server-level security. Research and choose a reputable host with strong security practices. Even on shared hosting, applying these tips provides essential protection for your specific website files and data.
7. Monitor and Use Security Tools
Stay vigilant and use available tools.
- Constant Monitoring: Keep an eye on your website’s activity logs, especially around login attempts and file changes.
- Use Security Software/Plugins: Depending on your setup (e.g., WordPress), install and configure reputable security plugins that can scan for malware, monitor file integrity, and block malicious login attempts.
Taking the First Steps
Implementing these basic security tips for your hosted website is an ongoing process, not a one-time task. Start with the most critical ones: strong passwords, HTTPS, and regular updates. As you become more comfortable, gradually incorporate more advanced measures like input validation in your code and regular backups.
Security for beginner coders is about building good habits early. By prioritizing these steps, you create a much safer environment for your website and anyone who visits it.
