How to secure SharePoint data in Microsoft 365?
SharePoint data in Microsoft 365 can be secured through the combination of access controls, retention policies, version history, MFA, and external backup. These features ensure that documents and lists are protected against accidental deletion, unauthorized access, and data corruption, while allowing organizations to recover data quickly when needed.
Protection mechanisms for SharePoint data
SharePoint offers multiple layers of security to protect data against internal and external threats.
Eligibility check
Users can be assigned specific rights to restrict access to documents and lists, reducing the risk of accidental or intentional alteration.
Version history
Changes to documents are saved as versions, making it possible to restore previous versions if something goes wrong.
Retention policies and Legal Hold
Retention policies ensure that important data is kept for a defined period of time, while Legal Hold prevents data from being deleted during legal investigations.
MFA and identity protection
Multi-Factor Authentication and identity protection prevent unauthorized access to SharePoint data.
External backup
Third-party backup solutions provide additional protection by storing separate copies of SharePoint data outside the Microsoft 365 environment.
Audit logs
Audit logs track changes and access, facilitating recovery and accountability.
Data encryption
Data is encrypted both at rest and in transit to protect against unauthorized access and interception.
Recommended actions
- Configure permissions: Restrict access to files and lists as needed.
- Enable version history: Ensure rollback in case of incorrect changes.
- Implement retention policies: Retain critical data according to company rules.
- Use MFA: Protect user accounts against unauthorized access.
- External backup solutions: Create separate copies for long-term security.
