What tool can aid in monitoring and responding to security incidents in Azure?

Azure Sentinel is a cloud-native security information and event management (SIEM) solution that provides advanced capabilities for monitoring and responding to security incidents across an Azure environment. It is designed to intelligently collect and analyze security data from various sources, using artificial intelligence and machine learning to identify threats and anomalies effectively.

This tool enables organizations to set up alerts, automated responses, and workflows aimed at improving their security posture. It allows for real-time visibility into potential security threats, simplifying the investigation and response process for security teams. Azure Sentinel integrates seamlessly with other Azure services as well as third-party apps, making it a comprehensive solution for centralized security monitoring.

In contrast, other options serve different purposes; Azure Traffic Manager is focused on traffic routing and performance management, Azure Functions facilitates serverless compute solutions for running code, and Azure DevTest Labs helps in managing development and test environments. None of these provide the specialized incident response capabilities that Azure Sentinel offers, making it the optimal choice for security monitoring and incident management in Azure.
