Least Privilege Model in Solaris 10
"The least privilege model evolved from Sun's experiences with Trusted Solaris and the tighter security model used there. The Solaris 10 OS least privileged model conveniently enables normal users to do things like mount file systems, start daemon processes that bind to lower numbered ports, and change the ownership of files. On the other hand, it also protects the system against programs that previously ran with full root privileges because they needed limited access to things like binding to ports lower than 1024, reading from and writing to user home directories, or accessing the Ethernet device.
