Best Practices For Securing Drupal Websites In 2023

With the ever-evolving world of technology and internet security, it is essential for web developers to stay on top of best practices for protecting their Drupal websites. Despite still being early in the game of staying ahead of the security curve, the investment now could save a lot of unwanted headaches later. In this blog post we will discuss why securing your Drupal website is an important precaution to take in 2023 and how you can go about doing that. From understanding password complexity requirements to using secure hosting services and more, there are a few specific steps you'll want to be taking as soon as possible if you're looking to keep your online presence safe from potential threats such as hackers or malicious attacks.

In this comprehensive guide, we will discuss the common security risks associated with Drupal websites, the latest trends in cyber security, and practical tips on how to harden website security.

Common Security Risks Associated with Drupal Websites:

1. Vulnerable Third-party Modules:

Drupal websites often use third-party modules which can be vulnerable to security exploits. Keeping these modules up-to-date is crucial for security. Make sure to only use trustworthy and reliable sources.

2. Weak Passwords:

Weak passwords can be easily guessed or hacked, allowing unauthorized access to the website. It is recommended to incorporate strong passwords and to utilize multi-factor authentication.

3. SQL Injection Attacks:

SQL injection attacks occur when attackers insert malicious code into input fields, leading to unauthorized access and data theft. Drupal websites can be protected from such attacks by installing web application firewalls.

4. Cross-site Scripting (XSS) Attacks:

XSS attacks occur when attackers inject malicious scripts into websites, leading to unauthorized access and data theft. Drupal websites must be protected from such attacks by implementing web application firewalls and sanitizing user inputs.

5. Lack of Regular Updates:

Regular updates are crucial for fixing security vulnerabilities and preventing data breaches. Drupal websites should be regularly updated, including third-party modules and core updates.

Practical Tips for Securing Drupal Websites:

Keep Drupal Up to Date

To ensure the security of your Drupal website, it's crucial to regularly update the CMS with the security patches that Drupal frequently releases. If you're currently using Drupal 7, you should begin planning to migrate to Drupal 9 since Drupal 7 support will end in 2022. Similarly, Drupal 8 support will end in November 2025, so it's important to start planning to move to Drupal 9. You can seek assistance from Drupal specialists and consultants to help you plan and carry out the upgrade to Drupal 9.

Install Security Modules

To improve the security of your Drupal website, it is crucial to install security modules. Drupal offers a variety of such modules, which add extra layers of protection against common attacks like cross-site scripting (XSS), SQL injection, and brute-force attacks. Installing and configuring these modules can help strengthen your website's security and decrease the chances of unauthorized access or data breaches. These modules often offer features like user access controls, activity logging, and intrusion detection, allowing you to monitor and mitigate potential security threats. By leveraging these security modules, you can proactively safeguard your Drupal website and ensure the confidentiality, integrity, and availability of your valuable data and resources.

Use Secure Passwords

To prevent attackers from accessing your Drupal website, it's important to use strong passwords that include a combination of upper and lowercase letters, symbols, and numbers. Avoid predictable passwords like "password" or "123456". You can also enhance your website's security by enabling two-factor authentication (2FA) as an extra layer of protection.

Secure Your Drupal Files

To safeguard your Drupal website from unauthorized access and malicious attacks, it is crucial to secure your Drupal files. This can be achieved through the use of proper file permissions, which will ensure that only authorized users can access sensitive files. Furthermore, it is important to regularly backup your files to enable quick restoration in case of any disasters. Finally, make sure to use encryption when transmitting files.

Secure Your Drupal Database

To avoid data theft, it is critical to secure the essential information in your Drupal database. Ensure that your database is not publicly available and can only be accessed securely through authorized methods. Use strong passwords for your database and change them frequently. Enabling the PHP filter function will help to ensure that no PHP code is directly written into your database fields and that only trusted HTML entities are permitted.

Use SSL Certificates

SSL or TLS is a technology that encrypts data as it goes from a user's browser to your website's server. To show users that they're visiting a secure site, SSL certificates replace the "http" in the URL with "https". By installing a valid SSL certificate, you can make your Drupal website more secure with HTTPS. Additionally, using HTTPS may give your site a small boost in search engine rankings, so securing your website isn't just a security measure but also a potential ranking signal. Additionally, using an SSL certificate helps protect against "man-in-the-middle" attacks, which can give attackers access to sensitive data like credit card numbers and passwords.

Limit Access to Drupal Admin Area

To ensure website security, only authorized individuals should be allowed access to the Drupal admin area. This will prevent hackers from obtaining confidential information like login credentials. Implement IP whitelisting or .htaccess to restrict access to the admin area. Additionally, enabling two-factor authentication can enhance the security of the Drupal admin area.

Use External Security Tools

External security tools, such as Web Application Firewalls (WAFs), can provide an additional layer of protection to your Drupal website. WAFs (Web Application Firewalls) are intended to identify and prevent harmful requests. This safeguards your website against potential attacks from hackers or malware. Additionally, it is important to utilize security audit scanners and vulnerability scanning tools that will detect any potential vulnerabilities in your system. This will allow you to stay ahead of the curve when it comes to cyber threats and ensure your website is secure from all angles.

Regular Security Audits

Finally, it is essential to regularly conduct security audits of your Drupal website. An audit should include a review of existing security protocols and measures, as well as identifying potential new threats and vulnerabilities. Use tools like Acunetix, NetSparker, or OpenVAS for regular security scans. Additionally, periodic penetration tests are crucial foridentifying any weaknesses in the system. Audits are key for ensuring that your Drupal website remains immune to cyber threats.

Educate Yourself and Your Team

No matter how secure your Drupal website is, it is always important to stay up to date with the latest security best practices. Regularly educate yourself and your team on the potential risks associated with cyber threats and new developments in web security. Additionally, keep up with updates from Drupal and install them as soon as they are released. By staying informed, you can ensure that your website remains secure into the future.


Securing a Drupal website takes vigilance and dedication, but these efforts will pay off in the long run for any organization or individual seeking to protect their valuable data and resources.Ultimately, the key is staying informed, being proactive, and taking all necessary measures to keep your website safe from cyber threats.With the right approach, you can protect your data and resources and stay ahead of malicious actors.Good luck!
