Remove any unused plugins or themes

[rifathasan]

Review your list of installed plugins and themes from time to time. If they are not actively used, they are usually not noticed for updating. Then, if vulnerabilities are discovered, they become a weak link in your WordPress security. The best practice is to remove unused themes and plugins from your WordPress site. At the very least, remove those that are deactivated.

Implementing user management policies
Hackers want to gain access to your site, and the fastest and most effective way to do this is to gain control of the administrator account. They can also infiltrate a user account and skype database update it to gain administrator rights using malware, although this is more difficult to do. Either way, user accounts can become a gateway to your site. For this reason, certain steps must be taken to ensure that none of your user accounts are currently compromised and to prevent them from being compromised in the future:

MalCare WordPress Activity log
Set up an activity log : Unexpected changes to users, files, posts, settings, plugins, themes, or any other part of a site can be an early sign that a user account has been compromised . In fact, many hackers take advantage of poor logging to hide their activities.
Check users regularly: Website management can change over time, such as writers and editors coming and going. Monitor users and remove those who no longer need access to the site. Inactive user accounts have the same password as before. If they have reused their password elsewhere and it is part of a breach, your site is vulnerable.
Implement a policy of least privilege: Give each user only the access to your site that they need. A writer does not need administrator access, and neither does an editor. Limit the number of administrator users in general.
