$3)$ Operating System and Computer System Management:

Imagine your company would like to upgrade the systems due to security threats. You need to prepare

a proposal draft where your task is to identify at least three major types of threats to systems running

Windows and the policies that system administrators must take to protect the system from

unauthorised access. Compare the practical problems when balancing the need for accessibility with

the need to restrict access and suggest the first action you would take to secure a Windows computer

or network if you managed one.
