  • Conduct Regular Audits: Periodically review all user accounts, removing those that are inactive or outdated.
  • Enable Email Alerts for Role Changes: Stay informed of any changes in user privileges.
  • Apply Principle of Least Privilege (PoLP): Ensure every user operates with the minimal level of access.
  • Disable User Registration if Not Needed: If your site doesn’t need open registration, disable it to prevent automated bot sign-ups.
  • Monitor User Activity: Use plugins like WP Activity Log to keep an eye on user actions and quickly identify suspicious behavior.
