Re: How much does it cost an attacker these days to launch a large-scale attack?
"The real question here is how do we produce an OS that completely denies all admin level privilege to the end-user, also lets them do what they want, where installation / upgrade / additional software is all controlled by professionals and its health is continually monitored by same?"
Errr, maybe Z/OS ?
Truth is, it'll never happen for consumer-level equipment because consumers need to "consume" to keep the money flowing to the producers, and anything that seriously impedes the consuming is a Bad Thing and must be stopped. Security can go straight to hell and hang when there's money to be made.
maybe I'm a bit cynical...
