Ordinary users are granted only enough permissions to accomplish their most common tasks. UNIX systems have built-in security features. Most users cannot set up a new user account nor do other administrative procedures. The user “root” is a special user, something called super-user, which can do anything at all on the system.
Remote users are unable to access the built-in administrator account. A Windows administrator account is not an exact analogue of the Unix root account – Administrator, the built-in administrator account, and a user administrator account have the same level of privileges. The default user account created in Windows systems is an administrator ...
The arrow represents a rootkit gaining access to the kernel, and the little gate represents normal privilege elevation, where the user has to enter an Administrator username and password. 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 ...
The file owner is 'root' and the SUID permission is set (the '4') - so the file is executed as 'root'. The reason an executable would be run as 'root' is so that it can modify specific files that the user would not normally be allowed to, without giving the user full root access. A default use of this can be seen with the /usr/bin/passwd binary ...
This enables users to be treated temporarily as root (or another user). The set group ID, setgid, or SGID permission. When a file with setgid is executed, the resulting process will assume the group ID given to the group class. When setgid is applied to a directory, new files and directories created under that directory will inherit their group ...

An inheritance is a windfall that can absolutely help someone's financial situation -- but it can make your taxes tricky. If you inherit property or assets, as opposed to cash, you generally don ...
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]
