Microsoft 365: Information Barriers (IB) upgrading from IB v1 to IB v2 with new capabilities

🚨 The Signal: Information Barriers (IB) V2 is now available, offering enhanced segmentation and discoverability. Existing IB V1 tenants must opt-in to upgrade, while new IB deployments will automatically use V2. This improves data segregation capabilities.

The Impact

Security teams and compliance officers are affected, with a low risk of misconfiguration if not properly managed.

• Security Teams: Must plan and execute the V1 to V2 upgrade.
• Compliance Officers: Can leverage new capabilities for stricter data segregation.
• Existing IB V1 Admins: Require action to gain new features.
• New IB Deployments: Automatically benefit from V2 capabilities.

The Action

1. Review Microsoft documentation for Information Barriers V2 capabilities and upgrade process.
2. Plan the upgrade from IB V1 to IB V2, considering new segmentation and discoverability features.
3. Execute the opt-in upgrade process for existing IB V1 tenants via the Microsoft Purview compliance portal.
4. Validate existing Information Barrier policies and create new ones to leverage V2 enhancements.
5. Communicate changes to relevant stakeholders regarding improved information segregation.
