Security Catalyst: Family Security Series Podcast, Episode 2 – Using a Non-Administrative User

You are invited to learn how to reduce the effectiveness of attacks and sleep better at night by using a non-administrative user account. In this brief podcast, we explain:
-    why you should be using a non-administrative user account
-    how to determine which type of account you are currently using
-    how to create normal user accounts
-    how to change to a regular user account

Thanks to a dedicated team of professionals, this podcast has been made better. If you see them on the street, give them a big hug. They worked hard (and continue to) to improve our efforts to make a difference:

• Gary Morgan, CISSP
• Alvin Liau, CISSP
• George Viconovic, MCIW/D

Links and Information Mentioned During the Program

Least Privilege

In computer science and other fields the principle of minimal privilege, also known as the principle of least privilege or just least privilege, requires that in a particular abstraction layer of a computing environment every module (such as a process, a user or a program on the basis of the layer we are considering) must be able to access only such information and resources that are necessary to its legitimate purpose.
Source: Wikipedia: http://en.wikipedia.org/wiki/Principle_of_least_privilege

Determine the current status of a user account

Two basic options in windows XP
Windows XP: Option 1
• Start -> Run -> CMD (bring up a command prompt)
• type ipconfig /renew (this will be in the show notes)
• Limited Users will be given an error that access is denied.  Administrators will be allowed to renew their IP address.

Windows XP: Option 2
• Start –> Control Panel
• Launch the User Accounts application

If you are  a Limited User you will be presented with the option to Change your picture or to click on Mail or User Accounts.  • You are limited to changing your own password
• changing your picture
• or to set up your account to use a .NET Passport.

If you are an Administrator you will be given the option to Change an account, create a new account or change the way users log on or off.

    Hello.

    I’m very happy that the idea of limited user accounts seems to get some traction, since this is one of the most important things which could reduce security problems. I think you’ve done a very good job explaining the gist of the issue (btw. OpenID rocks :)), however one thing I missed from the explanation, and personally I think it is needed to give a truthful picture to those who wish to embark on this journey are the possible problems they might encounter (like programs refusing to install / run). While this doesn’t look good when you “try to sell” them to the idea of running as limited user, it might be good if they were at least warned. Also, there are many methods of temporarily elevating your privileges (I covered it a while back on my blog - http://hype-free.blogspot.com/2006/09/non-hacking-tutorial-on-elevating.html) which should have been discussed (imho) in the podcast.
