WordPress Multisite is a powerful platform that allows users to manage multiple websites from a single installation. However, with great power comes great responsibility. WordPress Multisite security risks can be more complex than on a single WordPress site, making it crucial to take proper precautions to protect your websites.
User Roles Management
It’s important to assign roles based on the level of access required for each user. This means that not all users should have access to all parts of your website, especially the sensitive ones. For instance, you should only grant administrator access to trusted individuals who need to make changes to the site’s core functionalities.
Regularly reviewing and updating user roles is also crucial to maintain the security of your WordPress Multisite. This means checking if each user still needs their current level of access and updating their roles accordingly. For example, if an employee no longer works for your company, you should remove their access to the website to prevent any potential breaches.
Lastly, it’s important to remove any unnecessary user roles. This means getting rid of any roles that are not needed or are redundant. The fewer user roles that exist, the easier it is to manage access and ensure that there are no security loopholes.
Plugin Selection
It’s crucial to avoid using plugins that have known vulnerabilities or that have not been updated in a while. These plugins are more likely to be exploited by hackers and can cause security breaches on your WordPress Multisite. It’s important to always choose plugins from reputable sources and to research any plugin before installing it.
Another important step in choosing secure plugins is to check the plugin’s reputation and reviews. Look for plugins with a high rating and many positive reviews from users. You can also check online forums and communities to see if any users have reported security issues related to the plugin.
Lastly, it’s important to limit the number of plugins used on your WordPress Multisite. The more plugins you have installed, the higher the likelihood of vulnerabilities and conflicts. Only install the necessary plugins that provide essential functionality for your website. Regularly review and remove any plugins that are no longer needed to further minimize potential vulnerabilities.
Updates
Updating WordPress Multisite and its plugins is crucial to maintaining the security of your website. Updates often include security patches and bug fixes that address known vulnerabilities and issues. Failure to update regularly can leave your website at risk of cyber attacks and other security breaches.

It’s important to stay up-to-date with the latest releases and update as soon as possible to avoid any potential security risks. However, it’s also important to test updates on a staging site before applying them to your live site to ensure compatibility with your website’s theme and other plugins.
