Interview Questions
What is Microsoft Azure Sentinel?
Azure Sentinel is Microsoft’s cloud-native SIEM (Security Information and Event Management) service with built-in AI (Artificial Intelligence) for analytics. It allows organizations to monitor security data across the entire enterprise and mitigates threats before they cause harm.
How does Microsoft Sentinel evaluate alerts?
Azure Sentinel evaluates alerts by correlating the different data streams using powerful analytics and AI, thereby identifying potential security threats. It further aggregates and prioritizes alerts to focus on what is most important.
What are the key components of an Incident in Azure Sentinel?
The key components of an Incident in Azure Sentinel are alerts, entities, and bookmarks. Alerts notify about potential threats, entities provide information about involved accounts, hosts, etc. and bookmarks store useful data points for further analysis.
How does automated response work in Azure Sentinel?
