IT Company in Lowell Explains How to Use SharePoint Permissions

Many organizations set up SharePoint to improve collaboration. While it is a convenient tool that offers a lot of automated organizational features, it is important not to ignore SharePoint permissions best practices. These best practices help reduce risk, support better security, accountability, and long-term control.

“Every permission decision in SharePoint affects how teams work, share, and protect information. Getting it right means fewer mistakes, faster collaboration, and stronger compliance.” – Michael Kourkoulakos, CEO of NENS

Over time, file libraries can fill up with one-off permission changes and inconsistent access rules. Users may have more access than they need, which can make it easier to delete or change sensitive content by mistake. These issues can slow down collaboration and create unnecessary risks.

In this article, a reliable IT company in Lowell outlines practical SharePoint permission best practices that help organizations reduce risk, improve access control, and maintain long-term security as collaboration environments continue to grow.

What Are SharePoint Permissions?

SharePoint permissions control who can access content on a SharePoint site and what actions they can take. These permissions help you manage access to files, lists, libraries, pages, and any other content you store on SharePoint.

In SharePoint, content such as documents or pages typically follows the same access settings as the area they belong to. However, it is possible to customize these settings for individual items by creating unique permissions. Doing so allows you to control who can view, edit, or delete specific content, helping to safeguard important information from unintended changes or deletions.

How Do SharePoint Permission Levels Work?

When a user accesses a SharePoint site, the system evaluates their permissions based on their group membership. SharePoint groups are mapped to permission levels that list all allowed actions. SharePoint checks the user’s group, examines the permission level associated with that group, and then determines what the user can do.

Permissions can be assigned directly to users, but this increases complexity. Using groups centralizes control. When you change the permission level of a group, everyone in that group is affected.

Custom permission levels can be created by combining specific actions into a new level. When assigned, that level applies those exact actions wherever it’s used. SharePoint enforces these permissions consistently.

SharePoint also uses Limited Access when a user has access to an item inside a library or list but not to the rest of it. This allows the user to reach the item without viewing other content. To make the most of SharePoint’s capabilities, organizations must adopt a disciplined approach to permissions.

8 SharePoint Permissions Best Practices

1. Use Group-Based Permissions Unless Completely Necessary

Assigning permissions to individuals makes it more difficult to manage permissions. SharePoint groups help you manage access more efficiently by allowing you to grant or remove access for multiple users at once. This makes audits easier and reduces the chance of mistakes when modifying access.

There are cases where individual permissions may be appropriate. For example, if a single user needs temporary access to a specific file or folder, assigning permissions directly may be faster than creating a new group. In those cases, set a time limit, track the exception, and remove access once the task is complete.

2. Avoid Breaking Inheritance Unless Completely Necessary

Inherited permissions help keep access structures consistent and easy to manage. Breaking inheritance creates isolated permission sets that require more effort to monitor and maintain. Over time, this can lead to confusion, especially if a user has access issues or during audits.

If you must break inheritance, keep the scope of the change narrow, document the reason for it, and revisit it often to confirm that it is still needed.

3. Adopt The Principle of Least Privilege

Only grant user groups the minimum level of access they need to perform their work. This reduces the risk of accidental changes or unauthorized data exposure. Over-permissioned users often introduce vulnerabilities that can be avoided with more limited access.

More than 90% of data breaches occur due to poor firewall configurations or outdated firewalls, and then excessive access permissions often make it easier for attackers to move laterally once inside. Limiting access helps reduce this risk by containing potential exposure points.

Avoid assigning broad permissions to groups that include users with varying access needs. If a user only needs read access, they should belong to a site visitors group, not a group with contribute or edit permissions.

4. Leverage Microsoft 365 Security Groups

Microsoft 365 groups allow for centralized user management across multiple services, including SharePoint. This reduces administrative overhead and improves consistency in access control. It also simplifies onboarding and offboarding processes.

When you integrate Microsoft 365 with Okta, Okta controls group membership as the primary identity source. Any changes you make in Okta automatically update in the linked Microsoft 365 groups.

This approach keeps permissions consistent without requiring you to manage access separately in each system. It also allows you to apply the same access policies across Microsoft and non-Microsoft tools from one place.

5. Avoid Granting Full Control to Standard Users

Full Control allows users to change settings, delete content, and modify permissions. This level of access should be limited to site owners or administrators. Misuse of Full Control can result in lost data or unwanted structural changes.

6. Restrict External Sharing

Sharing with external users should be limited and monitored. When necessary, it should be done through secure channels with expiration controls and minimal permissions. Allowing unrestricted sharing increases exposure and undermines internal access policies.

7. Always Document Permission Changes

Keep a clear record of who has access, what level they have, and why it was granted. This improves transparency and supports security audits or internal reviews. It also makes it easier to understand historical access decisions when questions arise later.

8. Review Permissions Regularly

Review your site permissions regularly to make sure only the right people have access. Remove users who no longer need access, especially when teams or projects change.
