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.

Overview of IT Service Management (ITSM)

In the security context, the ability to quickly identify and respond to threats is critical to reducing the risk of exposing valuable data and confidential information. However, in the day-to-day running of any large-scale IT environment, security isn't the only concern. Demands from the business result in high-priority requests for modifications or new technology implementations. The IT department is usually made up of many different roles, which each have a part to play in the implementation and ongoing management of multiple complex systems, and, without their assistance, the security team will struggle to respond to threats at the speed required to prevent a major impact.

So, how then do we ensure everyone is made aware of requests and issues, and can quickly and effectively respond? The role of a service management platform is primarily to log, track, and communicate the coordination of efforts required by each of the solution areas...
