Non-Privileged Account Use

Use non-privileged accounts or roles when accessing nonsecurity functions.

A user with a privileged account can perform more tasks and access more information than a person with a non-privileged account. Tasks (including unauthorized tasks orchestrated by attackers) performed when using the privileged account can have a greater impact on the system. System administrators and users with privileged accounts must be trained not to use their privileged accounts for everyday tasks, such as browsing the internet or connecting unnecessarily to other systems or services. Example You are logged in using your privileged account and you need to look up how to reset a non-functioning application which processes CUI. You should log on to another computer with your non-privileged account before you connect to the web and start searching for the reset information [b]. That way, if your account is compromised during the search, it will be your regular user account rather than an account with elevated privileges. Potential Assessment Considerations • Are nonsecurity functions and non-privileged roles defined [a,b]? • Is it required that nonsecurity functions only be accessed with the use of non-privileged accounts? How is this verified [b]?
