Tip #3: Assign Custom Permissions to SharePoint Groups (Owners, Members, Visitors)

Assigning ownership and managing access to owners and members reduces the risk of data breaches by ensuring that only authorized personnel have access to certain documents.

Restricting visitor access to your SharePoint sites will also prevent accidental or intentional dissemination of confidential information.

Tip #4: Appoint One Administrator Per Site or Site Group

Limiting the number of administrators per SharePoint site or group to one is a great way to safeguard sensitive data and files and prevent unauthorized access. You can easily add or remove site admins via the SharePoint Admin Center.

Tip #5: Set Admin Sharing Link Type and Link Permissions

To ensure only authorized users can access your SharePoint site, set the admin sharing link type to “SharePoint Open.” It’s also essential to ensure the site owner has complete control over link permissions to prevent unauthorized access to data or files.

An admin can use Windows group policy settings to restrict user access to certain parts of the site, employ web authentication and Two-Step Authentication, and use Active Directory Rights Management Services (AD RMS) to manage access to SharePoint content and files.

Tip #6: Check the Access Request Feature

Use the access request feature to manage who has access to specific areas of your SharePoint site. The feature controls who can view, edit, or delete files on your SharePoint site.

Access Requests can be configured to go to the site’s owner of an email address. Additionally, you can use the content security policy feature to restrict which websites users can visit from your SharePoint site.

Tip #7: Indicate Network Location

When configuring your SharePoint site, it’s crucial to indicate the network location to secure it from malicious attacks. Configuring your site to use SSL certificates and HTTPS protocol also adds an additional layer of security.

Tip #8: Use Microsoft 365 Security Defaults

Microsoft 365 Security Defaults provide basic security settings that can help protect your data from unauthorized access. With Microsoft 365 Security, you can configure user authentication and authorization requirements, monitor user activity, and track compliance with security policies.

Advanced features like Security Groups help you secure your SharePoint site against malware attacks and detect and prevent unauthorized access.

Tip #9: Implement Multi-factor Authentication (MFA)

With the increasing threat of cyber attacks, implementing MFA should be a top priority for any organization looking to secure its SharePoint site in 2023.

MFA requires users to provide two or more forms of identification before accessing the site, adding an extra layer of protection. Enabling MFA is a simple process; you can use standard login methods, such as passwords and PINs, alongside apps that generate unique codes for each login attempt.

Tip #10: Use the Virus Detection Feature in SharePoint Online

SharePoint Online provides a range of features to help you secure your site. One such feature is the virus detection option, which allows you to scan your SharePoint site for any viruses that may have infected it.

This feature is useful for scanning files and content on your site to prevent malware infection and potential unauthorized access.

Tip #11: Use the Encryption Feature in SharePoint

Encrypting your SharePoint content can prevent data breaches from unauthorized users.

SharePoint offers encryption features for access security, data security, application security, physical data center security, and network security for in-transit data. SharePoint Online also offers file- and disk-level encryption to secure data at rest.

Tip #12: Adjust Your Site’s Sharing Settings

One of the most effective ways to secure your SharePoint site is by adjusting your sharing settings. Use Windows permissions to limit access to specific folders and documents within your SharePoint site.

Strengthen your site’s network by configuring it properly and restricting sharing of specific folders to protect sensitive files on your SharePoint site.

Tip #13: Adjust Settings in Microsoft Teams

If SharePoint and Microsoft Teams are integrated with your organization, some settings and permissions will need to be managed in the Settings menu in Teams. Teams-connected sites will usually include additional information indicating the connection to Teams.

You will notice that certain settings will not be editable from SharePoint. You can configure settings for site permissions, sensitivity classification, and private channel membership in Teams, while site name, site description, and Hub association settings can be accessed within SharePoint.
