It is the nature of the Linux operating system and the POSIX security model that the root user has access to all system information stored on the local server. Due to this fact, some organizations choose to monitor the activities of privileged users.
If you are interested in monitoring such activities, two Novell products can assist you.
Privileged User Manager: This product lets you monitor root user activities on the OES server by collecting data, analyzing keystrokes, and creating indelible audit trails. For more information, see the Novell Privileged User Manager Documentation.
