If there is an application running on the system that is continuously in use (such as a network monitoring application), ask the SA what the name of the application is. Execute ps –ef \| more to determine which user owns the process(es) associated with the application. If the owner is root, this is a finding.

Fix Text (F-923r2_fix)
Configure the system so the owner of a session requiring a continuous screen display, such as a network management display, is not root. Ensure the display is also located in a secure, controlled access area. Document and justify this requirement. Ensure the terminal and keyboard for the display (or workstation) are secure from all but authorized personnel by maintaining them in a secure area, in a locked cabinet where a swipe card, or other positive forms of identification, must be used to gain entry.
