The Top-Rated Drupal Security Modules for Better Site Protection

Drupal offers numbers of security options to safeguard your website. Different versions for different platforms are available. The first step in securing your website as well the server is to make sure that you are using the most updated version of the module. It reduces the chances of the hacking attack to a great extent. The second step while talking about a website security is the secured communication through SSH, FTPS or HTTPS. Below mentioned drupal security modules are a great help when safeguarding your website against malicious attacks, all of which are perfect Drupal 7 modules.



CaptchaAs the name suggests, Captcha is a program that distinguishes between human and computer input in a given field. Its purpose is to block submissions from a robot. It is a proved and better way of securing your Drupal website against robotic submissions on the website from spammers who try to post everywhere they can.



Re-CaptchaRe-Captcha is the advanced version of Captcha, rather the reverse of Captcha. It is not a meaningless combination of words, but an excerpt or some mathematical calculation for the user to differentiate between human and a robot.

It has two sections of text instead of one as in Captcha. It is also used to digitize books. Google owns this service.



OauthOauth is an advanced tool for the authorization used in Drupal for security purposes. It provides a secure access to server resources. Two-level and three-level user identifications are involved to secure the website against any malicious attack.

When a user submits an authorization request to the server, this tool judges whether the user is a legitimate client for a particular website. The server then issues an approval for content usage to the visitors.



ACLAccess Control List, commonly known as ACL, is a Drupal API to be used with other modules. The purpose is to create a list of users for a website and assign them privileges. This tool has no user interface of its own and works only in coordination with other Drupal modules already in use.

This module is to be installed when other modules suggest, and it can be useful through their interfaces for any user list configuration.

Search Configuration


Search ConfigurationThis Drupal module increases the security of a website by altering the appearance of the search form, grouping similar contents together to have a meaningful search results and limiting the search options based on content type.

The configuration depends on the Role assigned to a user and does not restrict an admin user. This module provides an easy search form to its users. The search results are shown based on the role of the user.



SpamspanThis Drupal module is used to deal with the decoding email addresses of users to avoid email ID collection by spambots. Most email address obfuscators are largely depending on the JavaScript enabled in the browser on the client side. It increases the chances of bot attack. Spamspan handles this problem by turning email addresses into clickable links and turning them into text form like “example at example dot com”.

Menu Admin per Menu


Menu Admin per MenuTo increase security measures, Drupal allows adding, modifying or deleting menu items only to users having administrator menu permission. If you want some users of the website to manage primary or secondary links, but not the navigation, Menu Admin per Menu comes to your help here.

It is helpful when you do not want to grant full access to some users and want to limit them to link management only.



LDAPAs the name suggests, lightweight directory access protocol is used to integrate authentication and to authorize users for certain feeds and views. APIs and building blocks are provided to other modules through this module.

The major benefit that a website administrator gets by employing LDAP is that all the information into a single central repository can be secured with authentications. A lot of tweakings can be done with this module regarding user access for maximum usability.

Password Policy


Password PolicyA number of constraints are available to set a password in the Password Policy module. The purpose to set a complicated password is to increase the security against spambots. Whenever a user changes a password, a list of hints is offered to go for a complicated password including a combination of alphabets, numerals symbols, the minimum number of character and some other options. Password expiration feature is also available in this module that sets the number of days for the current password, and a password changing becomes mandatory after that.

Taxonomy Access Control


Taxonomy Access ControlThis module is related to access control for a specific user role and categories. Once configured, it automatically controls access of users to their specific nodes. These access permissions include view, update and delete.
Taxonomy Access Control currently supports MySQL/MariaDB databases. This module is highly recommended for websites that are content driven. It takes some time to be configured but once done, it does wonders for the website.
