    GTK+ Graphical frontend to su and sudo. [7] GKsu comes up automatically when a supported application needs to perform an action requiring root privileges. A replacement, "gksu PolicyKit", which uses PolicyKit rather than su/sudo, is being developed as part of GNOME. [8] kdesu: A Qt graphical front-end to the su command for KDE. [9] kdesudo:

    It is also possible to use polkit to execute commands with elevated privileges using the command pkexec followed by the command intended to be executed (with root permission). [9] However, it may be preferable to use sudo, as this command provides more flexibility and security, in addition to being easier to configure. [10]

    In information security, computer science, and other fields, the principle of least privilege (PoLP), also known as the principle of minimal privilege (PoMP) or the principle of least authority (PoLA), requires that in a particular abstraction layer of a computing environment, every module (such as a process, a user, or a program, depending on the subject) must be able to access only the ...

    en.wikipedia.org/wiki/Unix_security

    A core security feature in these systems is the file system permissions. All files in a typical Unix filesystem have permissions set enabling different access to a file. Unix permissions permit different users access to a file with different privilege (e.g., reading, writing, execution).

  8. Privilege escalation - Wikipedia

    en.wikipedia.org/wiki/Privilege_escalation

    Privilege escalation means users receive privileges they are not entitled to. These privileges can be used to delete files, view private information, or install unwanted programs such as viruses. It usually occurs when a system has a bug that allows security to be bypassed or, alternatively, has flawed design assumptions about how it will be ...

  9. Access-control list - Wikipedia

    en.wikipedia.org/wiki/Access-control_list

    In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
