Write a memo to management making a case for your decision. Detail the input that would likely influence your thinking.

It’s 5:30 AM on Black Friday, the day after Thanksgiving. You’re aware that your company’s retail stores will be opening at 6:00 AM and that millions of dollars of revenue will be flowing through the point of sale system that you administer.

While monitoring the server that manages all of the remote cash registers, you notice a malware warning message that appears suggesting that you update the server’s security software ASAP. Oddly, the warning is not displayed in the standard Microsoft dialog box format.

Downloading and updating the system’s security software requires that the entire point of sales system must be offline, probably for four hours or more.
