Let’s get started. Why Website Security Is Important A hacked WordPress website can cause serious damage to your business’s revenue and reputation. Hackers can steal user information and passwords, install malicious software, and even distribute malware to your users. Worse, you may find yourself paying ransomware to hackers just to regain access to your website. Every day, Google warns millions of users that a website they are trying to visit may contain malware or steal information. Furthermore, Google blacklists thousands of websites each day for malware or phishing. Just as business owners with a physical location are responsible for safeguarding their property, online business owners need to pay extra attention to their WordPress security. [Back to Top ↑] Keep WordPress Updated WordPress is open-source software and is regularly maintained and updated. By default, WordPress automatically installs minor updates. For major releases, you need to manually initiate the update. WordPress also comes with thousands of plugins and themes that you can install on your website. These plugins and themes are maintained by third-party developers, who regularly release updates as well. These WordPress updates are crucial for the security and stability of your WordPress site. You need to make sure that your WordPress core, plugins, and theme are up to date. [Back to Top ↑] Use Strong Passwords and User Permissions The most common WordPress hacking attempts use stolen passwords. However, you can make that difficult by using stronger, unique passwords for your website. We are not just talking about the WordPress admin area. Remember to create strong passwords for your FTP accounts, databases, WordPress hosting accounts, and custom email addresses that use your site’s domain name. Many beginners don’t like using strong passwords because they are hard to remember. The good thing is that you don’t need to remember passwords anymore because you can just use a password manager. See our guide on how to manage WordPress passwords for more information. Another way to reduce the risk is to not give anyone access to your WordPress admin account unless you absolutely have to. If you have a large team or guest authors, then make sure that you understand user roles and capabilities in WordPress before you add new user accounts and authors to your WordPress site. [Back to Top ↑] Understand the Role of WordPress Hosting Your WordPress hosting service plays the most important role in the security of your WordPress site. A good shared hosting provider like Hostinger, Bluehost, or SiteGround takes extra measures to protect their servers against common threats. Here are just a few ways that good web hosting companies work in the background to protect your websites and data: They continuously monitor their network for suspicious activity. All good hosting companies have tools in place to prevent large-scale DDoS attacks. They keep their server software, PHP versions, and hardware up to date to prevent hackers from exploiting a known security vulnerability in older versions. They have ready-to-deploy disaster recovery and accident plans that allow them to protect your data in case of a major accident. On a shared hosting plan, you share the server resources with many other customers. There is a risk of cross-site contamination where a hacker can use a neighboring site to attack your website. By contrast, using a managed WordPress hosting service provides a more secure platform for your website. Managed WordPress hosting companies offer automatic backups, automatic WordPress updates, and advanced firewall configurations to protect your website. They often handle many of the technical security tasks on this list for you. We recommend SiteGround as our preferred managed WordPress hosting provider. They have responsive support, fast servers, and excellent reliability. Make sure you get the best deal by using our special SiteGround coupon.
