Go figure: 90 percent of Windows 7 flaws fixed by removing admin rightsMikey 9 comments
Though it won't come as a surprise to those who have some knowledge of basic computer security, a study by Beyond Trust has confirmed (PDF) that simply removing admin privileges from users on Windows based PC's will fix around 90% of known flaws.
Your office IT guy already knows this and although some people find it annoying, he is justified in locking down your computer tighter than a Nun's corset.
"In total, 64 percent of all Microsoft vulnerabilities reported last year are mitigated by removing administrator rights. That number increases to 81 percent if you only consider security issues marked Critical, the highest rating Redmond gives out, and goes even higher to 87 percent if you look at just Remote Code Execution flaws. Microsoft published 74 Security Bulletins in 2009, spanning around 160 vulnerabilities (133 of those were for Microsoft operating systems)."
People in the know also know that an overwhelming majority of infections are caused by inexperienced users who simply click 'yes' and 'ok' to every prompt, which is one reason why MS introduced the UAC system and why your IT guy won't let you install that horrid browser toolbar.
