Playing with least privileges

Oracle Solaris 11, like other good UNIX-like operating systems, has a flaw in its inception; there is a privileged account called root that has all special privileges on a system and other accounts that have limited permissions such as regular users. Under this model, a process either has all special privileges or none. Therefore, if we grant permission for a regular user to run a program, usually we are granting much more than is needed, and unfortunately, it could be a problem if a hacker is to crack the application or the system.

In Oracle Solaris 10, developers have introduced a wonderful feature to make the permissions more flexible; least privilege. The base concept is easy; the recommendation is to only grant the necessary privilege for a process, user, or program in order to reduce the damage in case of a serious security breach.
