The principle (of least privilege) is widely recognized as an important design consideration towards enhancing and giving a much needed 'Boost' to the protection of data and functionality from faults ( fault tolerance) and malicious behavior . Benefits of the principle include: Intellectual Security. When code is limited in the scope of changes ...
Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations. [4]

[ 5] It originally stood for "superuser do", [ 6] as that was all it did, and this remains its most common usage; [ 7] however, the ...
A Linux-based system is a modular Unix-like operating system, deriving much of its basic design from principles established in Unix during the 1970s and 1980s. Such a system uses a monolithic kernel, the Linux kernel, which handles process control, networking, access to the peripherals, and file systems.
setuid. The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [ 1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run ...
