When you need to block external access to your most sensitive documents, Office 365 Data Loss Prevention policies and sensitivity labels combine to find and protect the documents. A really simple policy is enough to detect and block external access, and is covered by Office 365 E3 licenses. If you have E5 licenses, you can consider auto-label policies to find and protect sensitive documents at scale.
The Microsoft 365 Compliance and Security centers are roling out to Office 365 tenants where they’ll replace the old Security and Compliance Center over time. The new centers look fresher than the SCC, but looks can deceive and it’s much more important that the functionality exposed in the new portals work reliably all the time.
Office 365 supervision policies can now make use of artificial intelligence and machine learning to detect offensive language in email and Teams communications. The data model covers a wide range of problematic language, but only in English. You can go ahead and cheerfully continue to swear in French, German, and other languages with no danger of being detected by policy.
In a sign of how automation based on signals gathered by Office 365 will emerge to help administrators do a better job, the preview of the new Admin Center offered to create a DLP policy to protect some sensitive information that I had clearly overlooked. Well-intended as the portal was, its efforts to create the new policy failed. That’s not really important – it’s the glimpse into the future which is.
Office 365 offers different ways to apply encryption to important messages. When those messages hold sensitive data known to Office 365, like credit cards or passport numbers, we can define a transport rule or DLP policy to protect outbound email automatically. And while you can define rules and policies through the GUI, PowerShell is available too.
Microsoft thoughtfully provided Office 365 tenants with a Data Loss Prevention template for GDPR personal data. The only problem is that the rules in the template were too sensitive and started to block email.
