A help desk team was alerted that a company-owned cell phone has an unrecognized password-cracking application. Which of the following should the help desk team do to prevent further unauthorized installations from occurring?

Group Policy is primarily used within Windows environments to manage user and computer settings, which is not applicable for mobile device management, especially for company-owned cell phones that may not be part of a Windows domain. Therefore, it would not effectively prevent unauthorized installations on mobile devices.

Privileged Access Management (PAM) focuses on managing and securing access to sensitive systems and accounts rather than directly managing mobile devices. While it enhances security for privileged accounts, it does not address the installation of applications on mobile devices and would not prevent unauthorized installations.

Installing anti-malware software can help detect and remove malicious applications, but it is a reactive measure rather than a preventative one. It does not stop unauthorized applications from being installed in the first place, making it less effective compared to MDM solutions for controlling application installations.
