Learn Azure Sentinel

By: Richard Diver, Gary Bushey

Overview of this book

Azure Sentinel is a Security Information and Event Management (SIEM) tool developed by Microsoft to integrate cloud security and artificial intelligence (AI). Azure Sentinel not only helps clients identify security issues in their environment, but also uses automation to help resolve these issues. With this book, you’ll implement Azure Sentinel and understand how it can help find security incidents in your environment with integrated artificial intelligence, threat analysis, and built-in and community-driven logic. This book starts with an introduction to Azure Sentinel and Log Analytics. You’ll get to grips with data collection and management, before learning how to create effective Azure Sentinel queries to detect anomalous behaviors and patterns of activity. As you make progress, you’ll understand how to develop solutions that automate the responses required to handle security incidents. Finally, you’ll grasp the latest developments in security, discover techniques to enhance your cloud security architecture, and explore how you can contribute to the security community. By the end of this book, you’ll have learned how to implement Azure Sentinel to fit your needs and be able to protect your environment from cyber threats and other security issues.

Chapter 13: Operational Tasks for Azure Sentinel

As with any service or solution, an ongoing maintenance routine is a critical process to ensure timely service improvements, maintain operational efficiency, control costs, and—most importantly—ensure the service remains highly effective in detecting and responding to security issues.

In general, Security Operations Center (SOC) operations are performed by two distinct roles: SOC engineers and SOC analysts. In a small organization, this may be a single person carrying out both roles; in larger organizations, these roles will span many teams and will be carried out by dedicated professionals. In this chapter, we will provide details of the daily, weekly, and monthly tasks required for each role, and any ad hoc tasks that should be carried out as required.

The information in this chapter is meant to provide a starting point for your own planning and ongoing improvement, so you can carry out the necessary processes to...
