Office 365 Cloud App Security (OCAS) is very good at identifying potential problems for tenant administrators to investigate. But don’t think that it’s always right. Humans are often better at resolving issues than computers are, simply because we can use our wider knowledge of how applications work and the Office 365 datacenter network to understand what might be behind an alert. Humans might be slower than computers, but when it comes to resolving OCAS alerts, we’re always better.
Security alerts from Office 365 Cloud App Security now flow into the Office 365 Audit Log, which means that you can run the Search-UnifiedAuditLog to find the alerts. Unhappily, more work than should be needed is necessary to extract the interesting information from the alert records.
