Security requirements to be considered for Microsoft Data Migration

Question

What specific security requirements should be considered in case of Microsoft O365 and Azure Data Migration between tenants. Is there any specific checklist from Microsoft which can be considered as an initial starting point?

Thanks.

Regards.

Answer 1

Use the following

1. Identity and Access Management:
   • Ensure Multi-Factor Authentication (MFA) is enabled for all accounts involved in the migration.
   • Use role-based access control (RBAC) to limit permissions to only those required for migration tasks.
   • Ensure all user and service accounts used during the migration have strong, complex passwords and are monitored.
2. Data Protection:
   • Encrypt data in transit and at rest during the migration process.
   • Use secure transfer protocols such as HTTPS or SFTP.
   • Ensure that any data stored temporarily during the migration is encrypted and deleted securely after the migration.
3. Compliance and Governance:
   • Verify compliance with relevant regulations (e.g., GDPR, HIPAA) before, during, and after migration.
   • Document all migration activities for auditing purposes.
   • Ensure data retention policies are adhered to in the new tenant.
4. Network Security:
   • Use virtual private networks (VPNs) or other secure network connections for data migration.
   • Monitor network traffic for unusual activity during the migration process.
5. Logging and Monitoring:
   • Enable logging and monitoring to track migration activities and detect any unauthorized access or anomalies.
   • Use tools such as Microsoft Sentinel for enhanced security monitoring.
6. Endpoint Security:
   • Ensure that devices used for migration are secure and have updated antivirus and anti-malware software.
   • Limit access to migration tools and data to authorized endpoints only.
7. Third-Party Tools and Services:
   • Evaluate the security of any third-party migration tools or services used.

Ensure third-party vendors comply with your organization's security policies and standards.
