We are having some undesirable people carrying around root password; this is a concern for the security of the organization.
What is the best way that I could give these users access to only the files they need to access. These users need to have root access to some files and they should be able to reboot the system. I know that there is a way to give users a root access with RBAC. I would appreciate it if any of you could provide me with the steps of using RBAC. ACL could also be a solution that I am looking for; and if anybody has steps for ACL that would be great.
Thank you for your valuable time and suggestions.
