What is so special about Linux special permissions?

The suid and sgid permissions set on a binary executable file can be used to provide greater access (controlled by the program) than the user normally is provided.  The sgid and sticky bit permissions set on a directory can simplify using that directory for collaboration for a group of users.  This talk focuses on how these permissions affect files and directories, how to set them and the potential security risks of these special permissions.  Learn to make use of these powerful permissions to make a more flexible environment.
