Drupal is currently one of the most popular and open-source CMS and blogging platforms available for web content management.
However, being open-source and free means that there are many security flaws in the software, many webmasters feel that the source code can be compromised and can expose a certain webmaster’s website to varied security flaws and give potential hackers access to malign the content on the website or blog.
There is, however a plus side to being open source, the same modules that may have been compromised in terms of security can be fixed by developers and coders who can review the specific source code and help find flaws in it and report it to the Drupal security management team.
Thanks to the effort of such developers, a horde of enhanced security modules have been developed to fortify the security of Drupal; the top 5 modules are enlisted here:
CAPTCHA is one of the most useful and secure security module for Drupal that executes a challenge-response test for anyone who tries to submit some content on the website to prove that he/she is a human being and not a spambots by replying with a valid response. All kinds of spambots are eliminated with the help of Captcha techniques.
2) Secure Pages Hijack Prevention

SSL pages help to transmit private and confidential documents. Once this module is installed with any of your secure pages, your login information form data is fully secured on any of the user pages.
3) Taxonomy Access Control Lite
This module mainly helps in hiding content which should not be read by a specific user or group of users in order to maintain security of the document. The taxonomy of the node determines who has access to that specific content and who should be restricted. This add-on module can also help admins to grant views or delete and update permissions according to updated taxonomies.
4) AES Encryption
AES encryption is the strongest encryption method when it comes to encryption of data that needs to be saved from being compromised like legal documents and passwords. It can be used by both site owners and developers who can grant any credible user to view the passwords in simple text. This module helps developers by giving them a user-friendly API that can be utilized by setting the ‘aes_encrypt’ and ‘aes_decrypt’ functions.
5) Lightweight Directory Access Protocol (LDAP)
This module is simple and easy to use. It can be integrated with any kind of LDAP and helps in authorization, user authentication, user provisioning and granting access to feeds. It also helps build barriers like query and server configuration storage for optimizing security levels of Drupal.
These 5 modules or add-ons for Drupal help fortify the security of Drupal and any of its potential or hidden vulnerabilities. With the usage of such modules not only does your content become safe and secure, it also becomes easier to manage permissions and access to them by giving user-specific grants to the data. Your website becomes less-prone to malware attacks and cyber phishing with the usage of such smart and free modules.
