SharePoint is a powerful collaboration platform that allows teams to store, organize, and share information efficiently. One crucial aspect of SharePoint is understanding and managing permissions for sites, lists, document libraries, items, and files. In this article, we will provide a beginner’s guide to SharePoint permissions, focusing on the concepts of inheritance, breaking inheritance, and granting permissions at different levels within SharePoint’s hierarchy.

The infographic below helps you understand the connection between site, list, document library, item, and file permissions.

Understanding SharePoint Permissions Hierarchy

  1. Sites: In SharePoint, a site is a collection of web pages, lists, libraries, and other resources. Each site has its unique set of permissions that control access to its contents.
  • Lists: Lists are collections of related items, such as tasks, contacts, or announcements. Each list within a site can have its own set of permissions, independent of the site’s permissions.
  • Document Libraries: Document libraries are repositories for storing files and documents. Like lists, document libraries can have their unique permissions, allowing fine-grained control over access to specific files.
  • Items and Files: Items represent individual entries in a list, while files reside within document libraries. Each item and file can have its own permissions, providing granular control over who can view, edit, or delete them.

Inheritance and Breaking Inheritance

  1. Inheritance: SharePoint follows a hierarchical structure, where permissions can be inherited from higher-level objects to lower-level ones. By default, permissions are inherited from the parent object to its child objects, such as sites inheriting permissions to lists, and lists inheriting permissions to items.
  2. Breaking Inheritance: Breaking inheritance is the process of separating permissions between objects at different levels. When inheritance is broken, you can assign unique permissions to a specific object without affecting the permissions of its parent or sibling objects.

Managing SharePoint Permissions

  1. Assess Access Needs: Before assigning permissions, identify the access requirements for each site, list, document library, item, or file. Determine who needs to view, edit, or contribute to the content.
  2. Assign Permissions at the Site Level: Set permissions at the site level to control access for all its lists, document libraries, and items. Grant permissions to SharePoint groups or individual users based on their roles or responsibilities.
  3. Manage List and Document Library Permissions: For finer control, assign unique permissions to lists and document libraries. Consider breaking inheritance if specific objects require distinct access restrictions.
  4. Item and File-Level Permissions: If necessary, assign unique permissions to individual items or files within a list or document library. This allows you to limit access to sensitive or confidential information.

Default SharePoint Permissions Levels

Below is a table displaying the default permission levels in SharePoint and their corresponding access rights:

Permission LevelAccess Rights

ReadView items in lists, libraries, and pages
Limited AccessAccess to specific items, folders, or documents

Best Practices for SharePoint Permissions

  1. Plan Permissions in Advance: Design your permission structure carefully before implementing it in SharePoint. Consider the hierarchical relationships between sites, lists, document libraries, items, and files to ensure efficient and manageable permission management.
  2. Minimize the Use of Unique Permissions: While breaking inheritance can provide flexibility, it can also lead to complex permission structures that are harder to maintain. Use unique permissions sparingly and consider group-based permission management whenever possible.
  3. Regularly Review and Update Permissions: As team compositions change and requirements evolve, review and update permissions to ensure they align with current needs. Remove unnecessary permissions and consolidate similar permissions to maintain a streamlined permission structure.

Understanding SharePoint permissions for sites, lists, document libraries, items, and files is essential for maintaining a secure and efficient collaboration environment. By grasping the concepts of inheritance, breaking inheritance, and assigning permissions at different levels, you can effectively manage access and ensure that users have the appropriate permissions to work with SharePoint’s various components.
