Hey folks, after reading the excellent threads here on using a Limited User Account in Windows XP in conjunction with SuRun, decided to give it a try, and I have to say, I was VERY impressed. My question is, how secure exactly is the LUA/SuRun combo? Or how secure exactly is LUA itself in XP SP2? What are the possible exploits and vulnerabilities that can render such a system in state of compromise? eg. Possible ways for a malicious process to get around the access restrictions or gain administrator priveleges. Any help would be greatly appreciated!
