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 ...
Running applications with least privilege (for example by running Internet Explorer with the Administrator SID disabled in the process token) in order to reduce the ability of buffer overrun exploits to abuse the privileges of an elevated user. Requiring kernel mode code to be digitally signed. Patching; Use of compilers that trap buffer ...
This poses a security risk that led to the development of UAC. Users can set a process to run with elevated privileges from standard accounts by setting the process to "run as administrator" or using the runas command and authenticating the prompt with credentials (username and password) of an administrator account. Much of the benefit of ...
A privilege is applied for by either an executed program issuing a request for advanced privileges, or by running some program to apply for the additional privileges. An example of a user applying for additional privileges is provided by the sudo command to run a command as superuser ( root ) user, or by the Kerberos authentication system.
Repairing permissions can become necessary, but has become increasingly less so for versions after Panther (10.3). [1] In OS X El Capitan, Apple introduced a security feature called System Integrity Protection. With it enabled, root privileges are no longer able to change system files and folders, including their permissions.

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 ...
Changes to files in folders that standard users don't have permissions for (such as %SystemRoot% or %ProgramFiles% in most cases) Changes to an access control list (ACL), commonly referred to as file or folder permissions; Installing and uninstalling applications outside of: The %USERPROFILE% (e.g. C:\Users\{logged in user}) folder and its sub ...
