Website security best practices to protect your hosted website

Introduction

In today’s digital landscape, cyber threats are more sophisticated than ever, putting websites at constant risk of hacking, data breaches, and malware attacks. Whether you run a small business site, an eCommerce store, or a personal blog, safeguarding your hosted website is crucial to prevent unauthorized access and data loss. Implementing website security best practices ensures your site remains protected against these evolving threats. In this comprehensive guide, we’ll explore the best website security best practices to protect your hosted website from cyber threats.

Understanding website security risks

Before implementing security measures, it’s important to understand the potential risks your website faces. Cybercriminals employ a variety of tactics to exploit weaknesses, compromise data, and disrupt business operations. Below are the most common threats:

Hacking attempts

Hackers often use automated tools and scripts to search for security loopholes in websites. Once they find vulnerabilities, they may inject malicious code, gain unauthorized access, or deface your website. Common hacking methods include SQL injection, cross-site scripting (XSS), and remote code execution.

Malware infections

Malware, or malicious software, can silently infiltrate your website and cause significant damage. It can spread viruses, steal customer data, and redirect visitors to fraudulent sites. Website owners may not even realize their site is infected until it’s flagged by search engines or blacklisted.

Distributed Denial-of-Service (DDoS) attacks

DDoS attacks flood your website with excessive traffic, overwhelming the server and making your site slow or completely inaccessible. These attacks can disrupt business operations and damage your online reputation.

Brute force attacks

Cybercriminals use brute force attacks to guess login credentials by systematically trying multiple username and password combinations. Without proper security measures in place, attackers can gain unauthorized access and take control of your website.

Data breaches

Data breaches expose sensitive information, such as customer details, payment credentials, and business records. Leaked data can lead to financial losses, identity theft, and loss of customer trust. Websites that do not encrypt data or store information securely are prime targets.

Phishing attacks

Phishing involves tricking users into providing their credentials through fake login pages, deceptive emails, or fraudulent websites. Attackers create convincing replicas of legitimate websites to steal passwords, credit card details, and other personal information.

Man-in-the-Middle (MITM) attacks

In MITM attacks, cybercriminals intercept data exchanged between a user and a website, allowing them to steal login credentials, financial information, or other sensitive data. This is particularly dangerous on unsecured public Wi-Fi networks where data is transmitted without encryption.

Insider threats

Not all security threats come from external sources. Disgruntled employees, former staff, or third-party vendors with access to your website can intentionally or unintentionally cause harm. Implementing strict access control policies is essential to minimize these risks.

Understanding these threats is the first step in implementing robust security measures to protect your hosted website. In the following sections, we’ll explore essential strategies to mitigate these risks and keep your site secure.

Essential security measures to protect your website

1. Use a secure hosting provider

Choosing a reputable hosting provider with built-in security measures is the first step in website protection.

Opt for a provider that offers:

• SSL certificates
• Firewalls
• DDoS protection
• Automatic malware scanning
• Secure backups

Additionally, ensure that your hosting provider performs regular server updates, offers 24/7 security monitoring, and includes server-side security measures such as intrusion detection and prevention systems (IDPS). Adopting website security best practices starts with a strong hosting foundation.

2. Keep software, plugins, and themes updated

Outdated software is a major vulnerability that hackers exploit. Regular updates help fix security flaws and improve overall performance.

Best website security practices include:

• Enabling automatic updates for your CMS and plugins where possible.
• Removing unused or outdated plugins and themes to minimize vulnerabilities.
• Checking for security patches and applying them as soon as they are released.
• Using reputable plugin and theme developers who prioritize security updates.

3. Implement SSL encryption

Secure Sockets Layer (SSL) encryption ensures data exchanged between your website and users remains private and secure.

Benefits of SSL include:

• Encrypting sensitive information such as login credentials and payment details.
• Improving trustworthiness and SEO rankings (Google prioritizes HTTPS sites).
• Preventing man-in-the-middle attacks where attackers intercept data.

Use TLS 1.2 or higher for optimal security and ensure your SSL certificate is renewed before expiration. This is a fundamental website security best practice that every site should adopt.

4. Use strong passwords and enable two-factor authentication (2FA)

Weak passwords are one of the easiest ways for hackers to gain access to a website.

Strengthen login security by:

• Using randomly generated passwords with at least 12-16 characters.
• Implementing a password manager to store and autofill credentials securely.
• Enabling Two-Factor Authentication (2FA), which requires a second verification step, such as a mobile code or biometric scan.
• Restricting access by using IP-based login limitations or geolocation-based restrictions.

Enforcing strong authentication measures is among the top website security best practices to safeguard login credentials.

5. Regularly backup your website

Backups act as a safety net in case of cyberattacks, hardware failures, or accidental deletions.

Follow these best practices:

• Perform automated daily backups of your website’s files and databases.
• Store backups on multiple locations, including cloud storage and local offline copies.
• Ensure backups are encrypted to prevent unauthorized access.
• Regularly test backups to confirm they can be restored successfully.

A reliable backup strategy is one of the website security best practices that ensures recovery from unexpected security incidents.

6. Protect against brute force attacks

Brute force attacks involve repeated attempts to guess login credentials.

To mitigate this risk:

• Limit login attempts to prevent multiple failed attempts from the same IP.
• Use CAPTCHA verification on login pages.
• Change default login URLs (e.g., WordPress users can change “/wp-admin” to a custom URL).
• Implement account lockout mechanisms after multiple failed login attempts.

Blocking unauthorized login attempts is a critical website security best practice for preventing brute force attacks.

7. Install a web application firewall (WAF)

A Web Application Firewall (WAF) acts as a protective barrier, filtering and monitoring traffic before it reaches your website.

A WAF helps:

• Block common cyberattacks like SQL injections, cross-site scripting (XSS), and DDoS attacks.
• Detect and mitigate bot-driven attacks.
• Analyze traffic in real-time to identify and prevent suspicious activities.

Consider using cloud-based WAF solutions, which provide additional protection by filtering threats before they reach your hosting server. Implementing a WAF is one of the best website security best practices for proactive defense.

8. Scan for malware and vulnerabilities

Regular malware scanning helps detect and remove malicious files before they cause harm.

Best practices include:

• Using security plugins such as Wordfence, Sucuri, or SiteLock to perform automatic malware scans.
• Running vulnerability assessments to detect weak points in your website’s security.
• Scheduling regular penetration testing to simulate real-world cyberattacks and identify potential security gaps.
• Setting up security notifications to alert you of suspicious activities immediately.

Frequent malware scanning is among the most important website security best practices to maintain site integrity.

9. Secure file and directory permissions

File and directory permissions control who can read, write, or execute files on your server. Misconfigured permissions can expose your website to security risks.

Follow these guidelines:

• Set files to 644 and directories to 755 permissions for optimal security.
• Restrict access to sensitive files such as wp-config.php (for WordPress sites) by setting permissions to 600.
• Disable PHP execution in directories where it’s unnecessary, such as the uploads folder.
• Use .htaccess rules to restrict unauthorized access to important files and directories.

Configuring file permissions correctly is one of the key website security best practices to prevent unauthorized modifications.

10. Monitor website activity

Website monitoring helps detect security threats before they escalate.

Best practices include:

• Using security plugins that log and alert admin users about suspicious activities.
• Implementing real-time monitoring for unauthorized file changes, login attempts, and server errors.
• Setting up Google Search Console alerts to detect potential security issues like malware infections or manual penalties.
• Regularly auditing user roles and permissions to prevent unauthorized access.

Active monitoring is an essential website security best practice to quickly identify and mitigate security risks.

11. Secure your database

Databases store critical website data and can be a prime target for cybercriminals.

Improve database security by:

• Changing the default database prefix (e.g., for WordPress, change wp_ to something unique).
• Using strong database user credentials.
• Restricting database access to authorized IP addresses only.
• Enabling encryption for database connections.
• Performing regular database backups and storing them securely.

12. Secure APIs and third-party integrations

Many websites rely on APIs and third-party services for added functionality, but they can introduce security risks.

Protect your integrations by:

• Using OAuth authentication instead of API keys whenever possible.
• Restricting API access to specific IP addresses.
• Regularly reviewing API permissions and revoking unnecessary access.
• Ensuring third-party services follow industry-standard security practices.

Additional security measures

• Use secure FTP (SFTP) instead of FTP – SFTP encrypts data transfers, reducing the risk of interception.
• Limit user access – Grant only necessary permissions to users and revoke access when no longer needed.
• Regularly change security keys – In platforms like WordPress, updating security keys enhances authentication security.
• Deploy content security policy (CSP) – Helps prevent cross-site scripting (XSS) attacks by controlling content loading.
• Disable XML-RPC if not needed – XML-RPC can be exploited for brute-force attacks and should be disabled if not in use.
• Enable HTTP security headers – Implement security headers like X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy to add an extra layer of protection.
• Perform security audits – Conduct periodic security assessments to identify vulnerabilities and keep security policies updated.
