To UNIX enthusiasts, it may seem like a small step for Windowskind, but at long last, Win 2000 comes with a native switch user (su) command called runas As has long been established in the security world, performing tasks under the context of the least privileged user account is highly desirable Malicious Trojans, executables, mail messages, or remote web sites visited within a browser can all launch commands with the privilege of the currently logged-on user, and the more privilege this user has, the worse the potential damage Many of these malicious attacks can occur during everyday activities and are thus particularly important to those who require Administrator privileges to perform some portion of their daily work (adding workstations to the domain, managing users, hardware the usual suspects) The unfortunate curse of poor souls who log on to their systems as Administrator is that they never seem to have enough free time to log on as a normal user, as security best practices dictate This can be especially dangerous in today s ubiquitously web-connected world If an Administrator comes across a malicious web site or reads an HTML-formatted email with embedded active content (see 16), the damage that can be done is of a far greater scale than if it Joe User on his stand-alone workstation had made the same mistake The runas command allows everyone to log in as a lesser-privileged user and then to escalate to Administrator on a per-task basis For example, say Joe is logged in as a normal User to the domain controller via Terminal Server, and he suddenly needs to change one of the Domain Admins passwords (maybe because one of them just quit and stormed out of the operations center in a huff) Unfortunately, he can t even start Active Directory Users and Computers as a normal user, let alone change a Domain Admin password Runas to the rescue! Here s what he d do: 1 Click Start button | Run, and then enter

Our hero Joe has just saved himself the pain of logging out of Terminal Server, logging back in as Administrator, logging back out, then back in as his normal User Least privilege and efficiency rule the day One of the more obvious examples of smart use of runas would be to run a web browser or mail reader as a less privileged user This is where runas gets tricky, however, as a rather lengthy thread on the NTBugtraq mailing list detailed at the end of March 2000 (http://wwwntbugtraqcom) It was debated exactly what privileges would trump when a URL was called within a browser window on a system with multiple open windows, including some with runas /u:Administrator privilege One suggestion was to put a shortcut to the browser (minimized) in the Startup group, so that it always started with least privilege The final word on using runas in this way, however, was that with applications started via dynamic data exchange (DDE), such as IE, key security information is inherited from the creating (parent) process Thus, runas is never actually creating the IE processes needed to handle hyperlinks, embedded Word docs, and so on Parent process creation varies by program, so actual ownership is difficult to determine Maybe Microsoft will someday clarify whether this is actually a more secure practice than completely logging off of all Administrator windows to do any browsing Runas is not a silver bullet As pointed out in the Bugtraq thread, it mitigates some threats, but exposes some others (Jeff Schmidt) Use it wisely Hold down the SHIFT key when right-clicking a file in the Win 2000 Explorer an option called Run As is now available in the context menu
