Popular WordPress security plugins

Millions of websites are infected with malware every week. WordPress is a popular platform and is open to risks if not managed well. While WordPress is fairly secure and is further strengthened by regular patches and updates, it requires constant monitoring and checking for updates and patches.

Some of the suggested approaches include:

  • Keep the WordPress source files, themes, and plugins updated with latest versions and patches.
  • Change passwords regularly and use strong passwords.
  • Actively manage those users who are allowed editing access to WordPress. Ideally, limit access to avoid mistakes impacting the whole site or leaving a vulnerability open.
  • Consider implementing an SSL certificate to encrypt connections to your website and secure any data transfers.
  • Take regular backups.
  • Tighten what is allowed on posts, blogs, comments, and responses. Malware attacks are known to originate through user/subscriber posts and comments with misleading links and the intent to steal users’ personal information. Comments could include spamming or inappropriate language, and these need to be actively managed.

As with all other management needs on WordPress, there are security plugins that help improve and automate a number of these security management tasks.

WordPress security plugins: An introduction

Best practice: Think through your security approach based on the final content of your WordPress website, the site’s structure, and the visitor interactions that will be allowed on the website. For example, will there be multiple users working on website creation, upkeep, and updates? Will there be subscribers who can post comments and write feedback? Knowing the current and future approaches will help with selecting an appropriate security plugin, including decisions around if a free security plugin version will suffice or if a paid version is best.

WordPress security plugins add value by offering automated, real-time security monitoring; scanning of any uploaded files; malware checks, including scans for changes to core files; blacklist monitoring to ensure that users or comments on the blacklist are not allowed in; security hardening; solutions to act in case of a hack; firewalls; protection against denial-of-service (DoS) or brute-force attacks; and other features.

A brief look at plugins

Plugins are applications that can be “plugged in” to your website. Plugins bring in pre-coded features that allow quick feature setup. WordPress has a huge repository of free plugins apart from paid ones. Choose a plugin if it adds value to your users’ experience and enhances communication with your audience. Typical plugins make it easy to fill in forms, upload images, help track website activity by visitors, have chat boxes, enforce security, and more. Plugins are accessed by navigating to the administrative page > My Site > My Home > Tools > Plugins .

  • On clicking Plugins, a menu of available plugins is shown. Plugins can be searched by name or category (Engagement, Security, Appearance, and Writing). You can also sort by featured, popular, and new plugins.
