Security Administration Solution

I understand that Segregation of Duties is one of the important concepts for internal control in a management. It might be the most difficult and the most costly one to achieve. My Boss always concern about company management, especially the security of administration. We have many high confidential documents and information store in our PC. We need secure access of every administrative, so that we won’t easily leak out those information to outsider. We can’t take the risk of leak out important information to who might threaten our company status. I think I should ask boss to install the Symark PowerPassword for us, so that we can have the Linux user account management that able to provide best security administration solution.
