authz.dll - What is authz.dll?

authz.dll File Description:

The authz.dll module is a Role-Based Access Control (RBAC) interface that supplies an administrative tool to oversee authorization policy and a runtime that allows applications to perform access checks against that policy. The RBAC administration tool is supplied as a Microsoft Management Console (MMC) snap-in. It is part of the Authorization Framework of the Windows Operating System

The authz.dll module specifies access in terms of user roles that reflect a program's authorization requirements. The Windows users are designated different roles based on their job descriptions and these roles are assigned permissions to perform related tasks.

Authorization policy is linked separately from the authz.dll module code. The program designer specifies a set of low-level operations that are considered security sensitive and the authz.dll file then defines a set of tasks that map onto those operations. The tasks are designed to be understood by administrators and business analysts notwithstanding the existing operations.

The authz.dll file functions when confirmation that an authenticated principal- a user, a computer, a network device, or an assembly - has permission to perform an operation has been received. The authz.dll module helps the system to allow only authorized users to perform certain actions. The file also helps the Windows operating system prevent malicious acts.

Authorization of the program however, depends on the authentication processes. Before a user or a process can be authorized to view or to use specified resources, the authz.dll program must perform the authentication tasks. The authz.dll file creates an Identity object and an Principal object for authorization purposes, and determines how the program user can programmatically pass identity information to application logic that is remotely deployed.

The autz.dll component's authorization subsystem becomes a focal point for synchronization with other computer systems or other operating systems. The systems user may be able to reuse an application authorization framework across multiple applications if reuse is considered when designing the framework. Basically, reuse includes the code and the infrastructure that are availed to impose authorization capabilities.
