Each accessible object contains an identifier to its ACL. The privileges or permissions determine specific access rights, such as whether a user can read from, write to, or execute ...
A number of computer operating systems employ security features to help prevent malicious software from gaining sufficient privileges to compromise the computer system. . Operating systems lacking such features, such as DOS, Windows implementations prior to Windows NT (and its descendants), CP/M-80, and all Mac operating systems prior to Mac OS X, had only one category of user who was allowed ...

[7] WSL 1 is not capable of running all Linux software, such as 32-bit binaries, [41] [42] or those that require specific Linux kernel services not implemented in WSL. Due to a total lack of Linux in WSL 1 ...
The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with ...

An example of a user applying for additional privileges is provided by the sudo command to run a command as superuser user, or by the Kerberos authentication system.
The main parts of the chmod permissions: For example: rwxr-x---Each group of three characters define permissions for each class: the three leftmost characters, rwx, define permissions for the User class (i.e. the file owner). the middle three characters, r-x, define permissions for the Group class (i.e. the group owning the file)
