Question

What security factors do companies need to consider when buying an operating system?

Answer 1

Answer:

What they can do to prevent malware and hacking.

Explanation:

They would want the ability to have high security including strong firewalls and a minimal amount of loopholes in the OS itself. A company can't always rely on a patch to come through and would instead need something guaranteed to be nearly perfectly secure. For this reason, some companies choose Linux or Unix.
