Role-based Access Control
March 13, 2001
UNIX has always allowed users to be granted access privileges for running programs that they normally don't have access to. Even with modern-day Solaris, you still have the ability to set your user id and group id, as well as access control lists, and you can still use the venerable third-party sudo program.
Things have changed just a tad with Solaris 8, though. We now have a process known as Role-based Access Control (RBAC). Although sudo is a bit easier to set up, with RBAC you no longer need to compile another program to provide this functionality.
