We often encounter a common misconception among security executives and practitioners that Microsoft Sentinel can only be used for Azure Cloud resources.Īlthough this might have been the case at the start, Microsoft Sentinel allows to ingest and correlate data from a wide range of log sources located in a variety of cloud platforms ( Azure, AWS, and Google Cloud), on-premises networks and compute infrastructure, 3rd party security tools (including firewalls), or software as a service (SaaS) applications.Īnd Microsoft keeps on making significant improvements, for example on log collection: it is now possible to send custom-format logs from any data source to the Log Analytics workspace, and store those logs either in certain specific standard tables or in custom-formatted tables that you create. ![]() Is Microsoft Sentinel limited to Azure Cloud resources? As such you can view the alerts about possible data loss in the same view as the Microsoft 365 Defender incident queue, which allows you to refine the incident scope, without the need to switch screens. Microsoft Purview IntegrationĪnother nice feature is the integration of Microsoft Purview Data loss prevention alerts and incidents into Sentinel. These automation rules allow for a more intuitive construction of Security Orchestration and Automated Response (SOAR) activities, providing the ability to build combinations of playbook runs and incident updates (severity, ownership, status etc.) to match the required output. These can be triggered manually or set to run automatically when specific alerts are triggered. Playbooks can help to speed up response actions that would typically be undertaken by security analysts. Azure Logic Powered PlaybooksĪzure Logic Apps power “playbooks” are a sequence of procedures that can be run in response to a security alert. Next to that, the automation rules for alerts have received new functions which allow us to centrally manage the running of playbooks with more flexibility. Incidents, schema, and alerts can be shared between Microsoft Sentinel and Microsoft 365 Defender, providing a holistic view with a seamless drill-down for context, which improves the analysis and speed to respond to possible incidents. The advantage of the integration with Microsoft 365 Defender and the Microsoft Defender stack is that it provides a unified way to manage risk in the digital landscape under a single umbrella. ![]() Here are some examples: Microsoft 365 Defender Integration Over the past year, Microsoft has invested heavily in the unified integration capabilities. Cost EfficiencyĪzure Sentinel’s flexible, consumption-based pricing, avoids the requirement for long-term contracts and alleviates the limits of the capacity of on-premise resources like storage capacity. This guarantees a significant reduction in MTTR (mean time to restore) with average resolution times of minutes compared to hours with legacy security monitoring solutions. The playbooks for automated response provide a prerecorded way of dealing with an incident with consistency in response from any security analyst. This frees up additional time for those analysts to do investigation, threat hunting, or work on enhancements. Resource efficiencyĪzure Sentinel makes it possible for organizations to automate many of the administrative tasks traditionally performed by SOC analyst. The whole feature set of Microsoft Sentinel is developed to simplify security operations and speed up threat response with integrated automation and orchestration of common tasks and workflows. Microsoft Sentinel is not a new technology, but the development of the platform and the increase of functionalities makes mentioning it worthwhile. Microsoft Sentinel is a cloud-native Security Information Event Management (SIEM) and Security Orchestration, Automation and Response (SOAR) solution from Microsoft. ![]()
