Microsoft Sentinel: The beginner’s guide

Azure Sentinel is a cloud-based security information and event management (SIEM) solution that enables you to detect, investigate, and respond to threats in your Azure environment. Azure Sentinel is built on the Microsoft intelligence platform, which uses artificial intelligence (AI) and machine learning (ML) to help you find threats faster. Azure Sentinel integrates with other Azure services, such as Azure Active Directory, Azure Security Center, and Threat Intelligence Service so that you can get a comprehensive view of your security posture.

When to use Microsoft Sentinel

Microsoft Sentinel is a solution for performing security operations on your cloud and on-premises environments.

Components of Microsoft Sentinel

  • Workspace: Azure Sentinel is a workspace that enables you to collect, analyze and take action on security data from across your enterprise. The workspace aggregates data from your on-premises systems, cloud services and Azure resources. You can use the workspace to detect threats, investigate incidents and protect your organization.

  • Data connectors: Azure Sentinel connectors are a set of data connectors that allow you to import data into Azure Sentinel from a variety of sources. There are connectors for importing data from Azure Log Analytics, Azure Active Directory, and other services. The connectors let you configure data ingestion rules and schedule the import of data at regular intervals. You can also use the connectors to export data from Azure Sentinel to a variety of destinations.

  • Log retention: Azure Sentinel can be used to collect, store, and analyze massive data sets for security operations. You can use Azure Sentinel to collect logs from your resources and services in Azure. You can also use Azure Sentinel to collect and store data from other sources, such as on-premises systems and public clouds.

  • Workbooks: Workbooks provide a way to monitor your Azure Sentinel activity logs and alerts. You can use workbooks to help you troubleshoot problems, analyze data, and create reports. Workbooks are written in the PowerShell language and can include custom scripts, functions, and modules.

  • Analytics: After connecting your data sources to Microsoft Sentinel, create custom analytics rules to help establish risks and anomalous behaviours in your area. Analytics rules search for specific events or sets of events across your area, alert you when certain event thresholds or conditions are reached, generate incidents for your team to triage, investigate, and process.

  • Threat hunting: Threat hunting is the proactive identification and eradication of cyber threats before they cause damage. It’s a critical process for any organization that wants to protect its data and systems from falling victim to a malicious attack. Azure Sentinel is Microsoft’s cloud-based platform for threat hunting. It provides users with visibility into all activity across their organization’s network, including both known and unknown threats. Azure Sentinel can also help identify malicious actors, track their behaviour over time, and shut them down before they do any damage.

  • Watchlists: Azure Sentinel includes out-of-the-box watchlists that are preconfigured with the most common indicators of compromise (IoCs) and rules. You can use these watchlists to identify malicious or unauthorized activity in your environment quickly. You can create custom watchlists in Azure Sentinel to monitor specific activities or behaviours that you’re interested in. For example, you might create a watchlist for all failed login attempts or for files that were recently uploaded to your organization’s file share.

  • Automation playbooks: Azure Sentinel provides a powerful platform for security automation. Playbooks allow you to sequence tasks and manage workflows, making it easy to integrate Azure Sentinel with other Azure services and products. You can also use playbooks to orchestrate the actions of multiple agents, making it possible to scale your security operations.
