Azure Security Logging

Implementing Azure Sentinel

Azure Sentinel is a scalable, cloud-native, security information event management (SIEM) and security orchestration automated response (SOAR) solution

Introduction

Azure Sentinel is a scalable, cloud-native, security information event management (SIEM) and security orchestration automated response (SOAR) solution. It provides intelligent security analytics and threat intelligence across the enterprise, providing a single solution for alert detection, threat visibility, proactive hunting, and threat response.

How Azure Sentinel Works

Azure Sentinel collects data across all users, devices, applications, and infrastructure, both on-premises and in multiple clouds. By integrating with existing tools and using built-in machine learning algorithms, Azure Sentinel reduces false positives and helps security teams focus on the most important events. It also includes built-in orchestration and automation of common tasks and responses.

Implementation

Implementing Azure Sentinel involves several steps:

  1. Create a Workspace: Azure Sentinel uses Log Analytics workspaces to store data. If you don’t have an existing workspace, you’ll need to create one.

  2. Connect Data Sources: Azure Sentinel can collect data from a wide variety of sources. You can connect to your Microsoft services, other cloud services, and on-premises systems.

  3. Set Up Detection Rules: Azure Sentinel includes a number of built-in detection rules, but you can also create your own. These rules help you identify specific activities or patterns that may indicate a threat.

  4. Respond to Threats: When a threat is detected, Azure Sentinel can respond in a number of ways. This could include sending an alert, triggering an automated response, or creating an incident for further investigation.

Conclusion

Implementing Azure Sentinel can significantly enhance an organisation’s security posture. By providing a single, integrated solution for security information and event management, Azure Sentinel makes it easier to detect, investigate, and respond to threats. And because it’s cloud-native, it can scale to meet the needs of any organisation, no matter how large or complex.
