Security Operation Analyst are implementing M365 Defender Solution.How a combined solution is required for endpoints,identity,email and applications (XDR) for detecting and mitigate threats for company is done when we see their role in Modern SOC and services?

What are XDR, SIEM, and SOAR?

• Extended detection and response (XDR)

• Security information and event management (SIEM)

• Security orchestration, automation, and response (SOAR)

XDR -

XDR provides continuous detection and response to threats and addressing vulnerabilities within an IT environment.

Microsoft has created a full set of XDR solutions for laaS, PaaS, and SaaS solutions with Microsoft Defender for Cloud and Microsoft 365 Defender.

These combined solutions provide security posture management,threat and vulnerability detection and response,and governance of resources across Azure,Microsoft 365,Hybrid, and multi-cloud infrastructures of companies.

Microsoft 365 Defender provides XDR capabilities for end-user environments (email, documents, identity, apps, and endpoint); and Microsoft Defender for Cloud provides XDR capabilities for infrastructure and multi-cloud platforms including virtual machines, databases, containers, and IoT.

Beyond the capabilities of XDR is the ability to use this information for threat hunting and incident response.

SIEM and SOAR-

Microsoft Defender Solutions can provide logs, events, and data to SIEM and SOAR solutions. This includes Microsoft Sentinel and other third-party solutions.

A SIEM is a solution within a security operation center that gathers logs and events from various appliances and software within an information technology infrastructure. These SIEM solutions then review the logs and events for potential threats by searching for behavior that is not typical to best practices or may be seen as anomalous or atypical.

SOAR solutions complement SIEM solutions. SOAR solutions can add automation to the response of potential events identified as threats in the log files by initiating a workflow. As an example, consider an activity log from a device that has been accessed from a location that has been flagged as a threat. The SOAR can initiate a workflow to take that device offline and send an alert to the security operations response team to investigate.

Microsoft 365 Defender, Microsoft Defender for Cloud, and Microsoft Sentinel combinely a MSFT Azure native solution that allows for full threat detection and response for XDR, SIEM, and SOAR, along with advanced vulnerability and threat hunting, detection, and response for security operations.
