Definition of permissions in The Network Encyclopedia.

What is Permissions (in computer networking)?

Settings that you establish for a resource to control which users and groups can access the resource and what degree of access they have. Permissions are implemented at several levels in Microsoft Windows operating systems and other Microsoft BackOffice applications. Permissions are implemented in Microsoft systems using discretionary access control lists (DACLs), which are attached to the object they control.

Examples of permission types include the following:

  • Shared folder permissions:
    Can be applied to shared folders on Windows systems to control access to network shares by users


  • NTFS permissions:
    Can be applied to files and folders on NTFS volumes for both local and network control of access to the resources


  • Print permissions:
    Can be assigned to printers to control who can manage printers, manage documents, or print documents


  • Active Directory permissions:
    Can be assigned to objects within Active Directory of Windows 2000 using Active Directory Users and Computers


  • Exchange permissions:
    Can be assigned to objects in the Microsoft Exchange Server directory hierarchy to control who can administer different parts of an Exchange organization using the Exchange Administrator program


  • Public folder permissions:
    Can be assigned using Microsoft Outlook to files in public folders to control who can read, edit, or delete those files
