3.11.3 Access levels for programs
Objective
Access levels can be allocated to protect information; they can also be used to prevent
unauthorized operation or deliberate damage to the control system or machine.
With access authorization levels to files and directories, it can be defined as to which users
are authorized to execute which operations on a directory or a file in a file system. Operations
in this sense include:
● Reading the contents of a file (READ), copying the file or placing the file in an archive.
● Changing the contents of a file (WRITE) or deleting the file.
● Executing a file (EXECUTE).
● Listing and displaying a file in a directory (SHOW).
● Creating a file in a directory.
● Displaying or reading the contents of a directory.
● Creating or deleting a directory.
