        <li><strong>Strong Passwords:</strong> Use at least 8 characters with mix of letters, numbers, and symbols</li>
        <li><strong>Unique Usernames:</strong> Each user must have a unique username</li>
        <li><strong>Principle of Least Privilege:</strong> Only give users the access level they need</li>
        <li><strong>Regular Reviews:</strong> Periodically review user accounts and disable unused ones</li>
        <li><strong>Initial Passwords:</strong> Ask users to change their password after first login</li>
