sudo (/ s uː d uː / [4]) is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. [5] It originally stood for "superuser do", [ 6 ] as that was all it did, and this remains its most common usage; [ 7 ] however, the official Sudo project ...
Different operating systems offer distinct methods for applications to identify their security requirements: sudo centralizes all privilege authorization information in a single configuration file, /etc/sudoers, which contains a list of users and the privileged applications and actions that those users are permitted to use. The grammar of the ...
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 user, or by the Kerberos authentication system.
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 ...
Sudo command on Ubuntu to temporarily assume root privileges. Most Unix and Unix-like systems have an account or group which enables a user to exact complete control over the system, often known as a root account. If access to this account is gained by an unwanted user, this results in a complete breach of the system.
It aims to improve the security of Microsoft Windows by limiting application software to standard user privileges until an administrator authorises an increase or elevation. In this way, only applications trusted by the user may receive administrative privileges and malware are kept from compromising the operating system. In other words, a user ...

While Internet Explorer may still work with AOL Mail, it's no longer supported by Microsoft and can't be updated. For a more reliable and secure experience with AOL products, we recommend you download a supported web browser.
The most common way of ensuring computer security is access control mechanisms provided by operating systems such as UNIX, Linux, Windows, Mac OS, etc. [5] If the delegation is for very specific rights, also known as fine-grained, such as with Role-based access control (RBAC) delegation, then there is always a risk of under-delegation, i.e., the delegator does not delegate all the necessary ...
