Privilege escalation is the act of exploiting a bug, a design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user.
Linux kernel (<4.8.3) Dirty COW ( Dirty copy-on-write ) is a computer security vulnerability of the Linux kernel that affected all Linux-based operating systems, including Android devices, that used older versions of the Linux kernel created before 2018.
STRIDE is a model for identifying computer security threats [1] developed by Praerit Garg and Loren Kohnfelder at Microsoft. [2] It provides a mnemonic for security threats in six categories. [3] The threats are: Spoofing; Tampering; Repudiation; Information disclosure (privacy breach or data leak) Denial of service; Elevation of privilege [4]
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 ...
A privilege level in the x86 instruction set controls the access of the program currently running on the processor to resources such as memory regions, I/O ports, and special instructions. There are 4 privilege levels ranging from 0 which is the most privileged, to 3 which is least privileged.
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 ...

In computing, privilege is defined as the delegation of authority to perform security-relevant functions on a computer system. [1] A privilege allows a user to perform an action with security consequences. Examples of various privileges include the ability to create a new user, install software, or change kernel functions.
