6 WordPress Security Plugins to Protect Against SQL Injection Attacks

With the COVID-19 crisis pushing most businesses online, hackers are trying to make the most of this shift. Among the common hacks that have gained notoriety are SQL injection attacks. Hackers use SQL injections to hack into your backend files and insert malicious code. This code redirects your incoming traffic to unsolicited sites, mostly adult and illegal pharma sites.

WordPress sites are unfortunately always on hackers’ radars – simply because WordPress is the world’s most popular content management system. On the plus side, as with all things WordPress, there are solutions to this issue. However, with all these options, finding the right tools can be confusing. In this article, we look at six WordPress security plugins that can protect your site from SQL injection attacks and other malware and hacks. Before we dive in, let’s answer a few questions:

How hackers execute SQL injections

Hackers infiltrate into your database using SQL commands and insert malicious code into your database tables. Generally, they do this through input fields – like customer comments, contact forms, or search bars – present on most websites.

How SQL Injections Damage Your Business

Depending on the severity of the SQL injection, your WordPress website can suffer the following consequences:

  • You could lose sensitive and confidential data from your database, such as customer data, financial transactions, and user credentials, which hackers can later exploit.
  • You could lose website data that could take days or even weeks to restore.
  • Your website could be either suspended by your hosting platform or even blacklisted by Google – resulting in further loss of traffic.

Apart from these consequences, you also need to spend a lot of time and resources cleaning and restoring your website to normal. However, you can avoid all this by installing the right security plugin for your site.

To handle SQL injections and other forms of malware attacks, you need a security tool to provide complete protection for your website. This includes malware detection, clean-ups, and protection from future attacks.

We’ve detailed out the 6 which we think are some of the most comprehensive security plugins you should consider. Let’s check them out.
