In computer security, jailbreaking is defined as the act of removing limitations that a vendor attempted to hard-code into its software or services. [2] A common example is the use of toolsets to break out of a chroot or jail in UNIX-like operating systems [3] or bypassing digital rights management (DRM).
A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software. [1]
chroot is an operation on Unix and Unix-like operating systems that changes the apparent root directory for the current running process and its children.A program that is run in such a modified environment cannot name (and therefore normally cannot access) files outside the designated directory tree.
An unlocked bootloader, showing additional available options. Bootloader unlocking is the process of disabling the bootloader security that makes secure boot possible. It can make advanced customizations possible, such as installing custom firmware.
As a security and auditing feature, sudo may be configured to log each command run. When a user attempts to invoke sudo without being listed in the configuration file, an exception indication is presented to the user indicating that the attempt has been recorded. If configured, the root user will be alerted via mail. By default, an entry is ...
The command chown / ˈ tʃ oʊ n /, an abbreviation of change owner, is used on Unix and Unix-like operating systems to change the owner of file system files and directories. Unprivileged (regular) users who wish to change the group membership of a file that they own may use chgrp. The ownership of any file in the system may only be altered by ...
The name root may have originated because root is the only user account with permission to modify the root directory of a Unix system. This directory was originally considered to be root's home directory, [4] but the UNIX Filesystem Hierarchy Standard now recommends that root's home be at /root. [5]
Microsoft Windows and DOS directory traversal uses the ..\ or ../ patterns. [2] Each partition has a separate root directory (labeled C:\ where C could be any partition), and there is no common root directory above that. This means that for most directory vulnerabilities on Windows, attacks are limited to a single partition.
