Onboard a Single Subscription with Microsoft Defender for Cloud

In today’s post we will look at a targeted way to harness the full potential of your Azure security by integrating Microsoft Defender for Cloud with Microsoft Sentinel. This powerful combination allows for advanced threat detection, seamless monitoring, and a unified view of your security posture. We want to select our Sentinel data connectors while being thoughtful. The Microsoft Defender XDR data connector is the modern connector version that we should all use in most cases; but the legacy connector is useful when we have only specific subscriptions that we want to bring into Sentinel. The older, legacy connector, requires the manual selection of the subscriptions to include in the data ingestion; it is the perfect solution if you have a tenant that you only want 2 of the many subscriptions provisioned.

Detecting Common Email Inbox Rule Manipulation

This article dives deep into the world of Kusto Query Language (KQL) to show you how to create custom analytics rules for detecting high-volume email sends, both internal and external, that might indicate potential security breaches. By leveraging these KQL queries, you can gain valuable insights into your email traffic, identify suspicious patterns, and take proactive measures to safeguard your organization’s data. Targeting a high-risk behaviour from the most recent MDDR, we will explore finding inbox rule compromises on our o365 logs today.
