Related questionâis there a way to get a handle on the ratio of benign to malicious files in an organization?
It's *hopefully* going to be vanishingly small. I don't have a Windows box handy, but I'm sure that once you install Windows 10 and Microsoft Office, you're looking at 200K files or more. This Fedora laptop has over 200K files between /, /usr, and /usr/share, and it's not even a complete install. So if 1% of your users have been pwned and have malware on their boxes, and the average pwned user has 100 malicious files, and 200K files for a base install, you're looking at 0.0005% malicious files. And if you have a large archive server (I was running one that was over a half-billion files and 12 petabytes+ of data), that's going to dilute the percentage even more unless there's a lot of malware in the archive.... ********** Replies to EDUCAUSE Community Group emails are sent to the entire community list.
