The set of Microsoft 365 Defender services provides live remediation recommendations to reduce the attack surface. Here's an example of the Defender for Cloud Apps dashboard, which allows analysis to detect unusual behavior across cloud apps. Defender for Cloud Apps is Microsoft's cloud access security broker (CASB) solution that allows for monitoring of cloud services and data access in cloud services by users. Here's an example of how Defender for Identity sends alerts for known malicious activity related to ransomware attacks.ĭefender for Cloud Apps (previously known as Microsoft Defender for Cloud Apps) allows your analysts to detect unusual behavior across cloud apps to identify ransomware, compromised users, or rogue applications. Defender for Identity enables you to pinpoint suspect activity and accounts to narrow down the investigation.

Defender for Identity sends alerts for known malicious activity that actors often use such as DCSync attacks, remote code execution attempts, and pass-the-hash attacks. You use Defender for Identity to investigate known compromised accounts and to find potentially compromised accounts in your organization.
Here's an example of how Defender for Endpoint shows detailed ransomware activity. You can also collaborate with experts on demand for additional insights into alerts and incidents. In Defender for Endpoint, you have access to a real-time expert-level monitoring and analysis service by Microsoft Threat Experts for ongoing suspected actor activity. Here's an example of how advanced hunting queries can be used to locate known attacker behavior.
Your analysts can also perform advanced hunting queries to pivot off indicators of compromise (IOCs) or search for known behavior if they identify a threat actor group. Here's an example of an alert in Microsoft Defender for Endpoint for a pass-the-ticket attack. Your analysts can use Defender for Endpoint for attacker behavioral analytics. Defender for Endpoint can detect attacks using advanced behavioral analytics and machine learning. Defender for Endpointĭefender for Endpoint is Microsoft's enterprise endpoint security platform designed to help enterprise network security analysts prevent, detect, investigate, and respond to advanced threats. How DART uses Microsoft security servicesĭART relies heavily on data for all investigations and uses existing deployments of Microsoft security services such as Microsoft Defender for Office 365, Microsoft Defender for Endpoint, Microsoft Defender for Identity, and Microsoft Defender for Cloud Apps. This article content was derived from the A guide to combatting human-operated ransomware: Part 1 and A guide to combatting human-operated ransomware: Part 2 Microsoft Security team blog posts.
DART leverages Microsoft's strategic partnerships with security organizations around the world and internal Microsoft product groups to provide the most complete and thorough investigation possible. DART provides onsite reactive incident response and remote proactive investigations. The Microsoft Detection and Response Team (DART) responds to security compromises to help customers become cyber-resilient. Responding to the increasing threat of ransomware requires a combination of modern enterprise configuration, up-to-date security products, and the vigilance of trained security staff to detect and respond to the threats before data is lost. In criminal hands, these tools are used maliciously to carry out attacks. These actions are commonly done with legitimate programs that you might already have in your environment for administrative purposes.
