- Know the different levels and types of permits in SharePoint It is essential to protect information and manage access for computers and users.
- Precise configuration of groups, roles, and permissions at various levels (site, library, list, and item) allows security to be tailored to the real needs of any organization.
- SharePoint integration with Microsoft Teams It adds particularities that should be mastered for efficient administration without losing control or transparency over data and access.
Today, SharePoint has become one of the most widely used tools by all types of businesses and organizations for document management and internal collaboration. However, one of the most critical aspects – and often confusing for administrators and advanced users – is how to properly set permissions and internal security. Properly configuring who can access, edit, or share each resource is the foundation for ensuring the protection of sensitive data and avoiding daily headaches.
In this comprehensive guide, you'll find everything you need to know about managing permissions and security in SharePoint, as well as its integrations with Microsoft Teams. From understanding the permission hierarchy, predefined levels, granular management of lists, libraries, or specific items, to best practices, including the specifics of administration in hybrid environments and the importance of working well with groups and service accounts. Get ready to master SharePoint and make it your best ally in security and access control.
Why are permissions and security so important in SharePoint?
Access to information is the driving force behind collaboration in any digital environment. However, uncontrolled access can pose the greatest risk to data security and confidentiality. In SharePoint, the correct configuration of permissions Allows you to define exactly who can view, edit, delete, or share documents, lists, pages, or settings, and under what conditions.
Lax or chaotic management can lead to information leaks, operational errors, or even costly security breaches. Therefore, mastering the permissions is not optional: it is essential.
Basic principles of permission management in SharePoint
SharePoint structures security based on three key concepts: permission levels, groups, and inheritance.
- Permission levels: These are sets of individual permissions grouped together for easy assignment. For example, "Full Control" or "Read Only."
- Groups: They allow you to assign permissions in bulk to multiple users who share a common function or need.
- Heritage: Permissions are typically assigned at a higher level (such as the site or library) and inherited downwards, although they can be customized by breaking this inheritance at a specific point.
This scheme facilitates management and reduces errors, but it also requires a clear understanding of how accesses propagate across the different layers.
Default permission levels in SharePoint: much more than “read” and “write”
From SharePoint Online to on-premises SharePoint Server, there are several predefined permission levels that cover most common needs. However, understanding their scope and differences is essential before you begin customizing access for users or groups.
- Total control: It allows you to perform absolutely any action on a site, including managing permissions, creating or deleting elements, and even global configuration. Reserve this level for the most trusted administrators, as any mistake can have irreversible consequences!
- Design: This level allows you to view, add, update, delete, approve, and customize elements or pages within a website. Perfect for those responsible for the image and structure of portals.
- Edition: Users can create, edit, and delete items and lists, as well as manage their content, but always within established limits.
- Collaboration/Contribute: These levels (names may vary depending on the version of SharePoint) allow you to add, edit, and delete items from lists or libraries, as well as manage personal web parts. Very useful for work teams that need to modify documents or lists but without access to advanced settings.
- Reading/View Restricted: They grant access only to view the content, without the ability to modify, delete, or add anything to it. It is the base level for reviewers, auditors or external visitors.
- Limited access: Its function is to allow a user to access only a specific resource (such as a file) without granting access to the rest of the site or library. Very useful for sharing individual documents with external collaborators.
- View only: It allows you to view application pages and elements, but with additional limitations; it's designed for very specific contexts, such as with Excel Services.
On publishing sites (such as institutional portals), there may be additional levels such as “Restricted Reading,” “Approval,” or “Manage Hierarchy,” which further refine control over content and page publishing.
Individual permits: the fine print of security
The above levels are actually a set of individual permissions that determine exactly what actions each user can perform. For example, a user with “Manage Lists” permission can create and delete lists, but perhaps not approve items or manage public views.
Among the most common SharePoint permissions depending on the scope, the following stand out:
- List permissions: Manage lists, view, add, edit, and delete items, approve or publish versions, create alerts, discard changes, and more.
- Site permissions: Manage permissions, create and modify groups, manage global settings, view usage data and analytics, add or customize pages and themes, and more.
- Personal permissions: Manage personal list views, add or remove web parts on personal pages, update custom web parts.
Granular control over these permissions allows you to create custom levels tailored to the specific needs of an organization or project.
SharePoint Groups: The Key to Efficient Permission Management
Assigning permissions one by one quickly becomes a nightmare as the number of users grows. To avoid errors and improve agility, SharePoint always suggests the use of security groups.
- Default groups: When you create a site, SharePoint generates default groups such as “Owners,” “Members,” and “Visitors,” each with a standard permission level.
- Custom Groups: You can create groups for specific departments, projects, or profiles (for example, “Auditors” or “Marketing Team”) and assign them the necessary permissions on one or more resources.
- Nested groups: SharePoint allows one group to be a member of another, facilitating hierarchical access management (very useful in large organizations).
Always assigning permissions to groups, not individual users, is a key best practice for security and efficiency.
Differences between permissions on Team Sites and Communication Sites
SharePoint primarily distinguishes between two types of sites:
- Team Sites: Designed for internal collaboration, where permissions are typically more granular and restricted to team or project members.
- Communication sites: Aimed at sharing institutional or public information, where permissions tend to be broader and geared toward mass visibility, although advanced segmentation options still exist.
Choosing the right site type and permits from the start prevents you from having to redo structures later.
Setting permissions on lists and libraries: detailed control
One of SharePoint's strengths is that it allows you to manage permissions at a very granular level, even on lists, libraries, or individual items. This is achieved by breaking permission inheritance, allowing specific rules to be set for each resource.
List permissions
- List management: Create or delete lists, add/remove columns or public views, modify the structure.
- Add, edit, and delete items: Complete control over stored data.
- Approve or reject versions: Essential in environments where only certain users can publish changes.
- Alerts and notifications: Possibility of creating alerts to monitor changes.
Library permissions
- Add/Remove Documents: Control who can upload or delete files.
- Manage versions: Allows you to restore or delete old versions, essential for strict document control environments.
- Configure metadata and views: Adjust the way documents are organized and displayed.
Remember that by breaking permission inheritance, you'll need to manually manage future changes. Document these exceptions well and periodically review your configurations to maintain SharePoint security.
Permissions on individual elements: surgical safety
Sometimes you need a user or group to view or edit a single document, folder, or list item. SharePoint allows you to break inheritance at this level as well, by setting up a single, fully customized access "bubble."
This technique is especially useful when you need to share documents occasionally with external collaborators or auditors without exposing the rest of the information.
Inheritance Models: How Permissions Spread in SharePoint
Most of the time, permissions in SharePoint flow from the top down. That is, if you assign a permission to a site collection, all lists, libraries, and items within it will automatically inherit those permissions, unless you break inheritance.
When is it appropriate to break up an inheritance? Only in very justified cases: highly sensitive documents, temporary equipment, shared resources with external parties, etc. Abusing this concept causes chaos and increases the risk of human error.
Managing Permissions in Hybrid Environments: SharePoint Online vs. SharePoint Server
The permissions logic is similar on both platforms, but there are important differences depending on whether you work in the cloud (SharePoint Online/Microsoft 365) or on local servers (SharePoint Server).
- In SharePoint Online: Groups and permissions are closely tied to Microsoft 365 and Azure AD. Additionally, integration with Teams adds new access and visibility considerations.
- In SharePoint Server: A wider variety of support roles and access to low-level settings are available, including file system and registry permissions. Windows.
Service accounts, roles, and technical permissions in SharePoint Server
In on-premises deployments (SharePoint Server), security extends beyond the permissions visible from the user interface. This is where service accounts, technical groups, and database roles come into play.
- Administrative accounts: There are specific accounts for server farm administration, timing services, central administration, content crawling, Active Directory synchronization, and more. Never use a single account for everything or grant administrative permissions to application accounts.
- Group Requirements: There are groups like WSS_ADMIN_WPG, WSS_WPG or WSS_RESTRICTED_WPG that grant technical permissions over the file system, registry and other internal resources.
- Database roles: SharePoint uses roles such as WSS_CONTENT_APPLICATION_POOLS, SPDataAccess, or SharePoint_SHELL_ACCESS to control access to your SQL Server databases and stored procedures. It's essential to follow official recommendations to assign the minimum amount of permissions necessary and avoid excessive privileges.
Advanced system permissions: local resources and registry
For advanced administrators—especially in SharePoint Server—group permissions on the local file system and the Windows registry need to be considered.
- Files and folders: There are paths on your system (for example, %ProgramFiles%\Microsoft Office Servers\16.0\Logs) that require special read, write, or full control permissions for SharePoint services to function properly.
- Registry entries: Many essential registry keys for SharePoint require technical permissions for administration, diagnostics, document conversion, or credential encryption.
