The command su, including the Unix permissions system and the setuid system call, was part of Version 1 Unix.Encrypted passwords appeared in Version 3. [5] The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.

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 ...
After authentication, and if the configuration file permits the user access, the system invokes the requested command. sudo retains the user's invocation rights through a grace period (typically 5 minutes) per pseudo terminal, allowing the user to execute several successive commands as the requested user without having to provide a password again.
Modern Unix systems generally use user groups as a security protocol to control access privileges. The wheel group is a special user group used on some Unix systems, mostly BSD systems, [citation needed] to control access to the su [4] [5] or sudo command, which allows a user to masquerade as another user (usually the super user).
The result is that the application performs actions with the same user but different security context than intended by the application developer or system administrator; this is effectively a limited form of privilege escalation (specifically, the unauthorized assumption of the capability of impersonating other users). Compared to the vertical ...
In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser [i.e., uid=0], regardless of the name of that account; [1] and in systems which implement a role-based security model, any user with the role of superuser (or its synonyms ...
