Interview Questions for Microsoft Sentinel
Microsoft Azure is the market’s second most dominant cloud service provider. Several Fortune 500 and other top-tier firms take advantage of Azure’s different offerings. The Microsoft Sentinel service scales automatically to meet your needs, just like any other Azure service.
Microsoft sentinel correlates security logs and signals from all sources across your apps, services, infrastructure, networks, and people, regardless of whether they are on-premises in Azure or another cloud. Microsoft threat intelligence, which analyzes trillions of signals every day, is used by Microsoft’s built-in AI. And Microsoft’s machine learning algorithms, which have been improved over decades of security experience, sift through the noise from alerts, delving into it and evaluating thousands of unusual occurrences to return a perspective of threats that demand your immediate attention.
With Microsoft Sentinel, you can instantly gain valuable security insights from your cloud and on-premises data. Without such knowledge, it is impossible to comprehend security operations in the Azure cloud. This article will cover some of the Microsoft Sentinel interview questions and answers to help you crack your interview on your first attempt.
