Remote tools (remote assistance, SCCM, etc.) and third party tools like ScriptLogic's Privilege Authority and BeyondTrust's Privilege Manager, can bring the time to install an app down to minutes. As for checking apps, just not running as admin can stop the browse by hijacking and infection. However, you are right; apps should be check and added to an approved list and the install source should be placed in a central location and installed from there, not from the media or download the user "found." -Eric Eric Case, CISSP eric (at) ericcase (dot) com http://www.linkedin.com/in/ericcase

How long does it take your IT staff to install software that an end user needs? 2. How long does it take your IT staff to check such software for security issues? Presumably, this is the real reason why end user aren't allowed to install software. If your IT staff doesn't check software for security issues, they can make the same mistake. Do your admins even check for security problems with vendor software? I suspect it's not a thorough check. If the answers to the above questions are "long" and an end user needs the software ASAP (who doesn't?), then the end user will find ways to bypass this restriction in order to get the job done. Having a timely software installation process is critical to the success of this security solution. No sysadmin can anticipate what software is needed at any given point in time. I'm curious to see what the answers are to the above questions. My informal survey answers range from 1 day (ok) to 2 weeks (not ok). -Randy Marchany VA Tech IT Security Office
