Access Control with Setuid (Linux)
The Linux Setuid bit can be used to control access to data, without needing to issue grants to specific users or the public. This technique allows a user to operate on the data, but only when the user has accessed it through a specific application program. The data is otherwise inaccessible to the user. After the user has exited the program, the user cannot access this same data using any Actian X utility.
