Module 0: Other learning and support options

 

The Ninja training is a level 400 training. If you don't want to go as deep or have a specific issue, other resources might be more suitable:

  • Already did the Ninja Training? Check what's new​ in the Ninja training.
  • While extensive, the Ninja training has to follow a script and cannot expand on every topic. The FAQ companion to the Ninja Training tries to closed this gap.
  • Microsoft Sentinel's official learning path is best if you want step-by-step training to use Microsoft Sentinel's features.
  • You can now certify with the new SC-200 certification (Microsoft Security Operations Analyst) which covers Microsoft Sentinel. The  SC-200 is not a Ninja Training certification, but the exam is largely based on Ninja Training materials, making it a good learning path for the certification. You may also want to consider the SC-900 certification (Microsoft Security, Compliance, and Identity Fundamentals), for a broader, higher level view of the Microsoft Security suite.
  • Premier customer? You might want the on-site (or remote these days)  4 day Microsoft Sentinel Fundamentals Workshop. Contact your Customer Success Account Manager to arrange.
  • Already a Ninja? Just keep track of what's new, or join our Private Preview program for an even earlier glimpse. 
  • Have a good feature idea you want to share with us? Let us know on the Sentinel user voice page.
  • Have a specific issue? Ask (or answer other) on the Microsoft Sentinel Tech Community. As a last resort, send an e-mail to MicrosoftSentinel@microsoft.com.

Module 1: Get started with Microsoft Sentinel

 

Short on time? Watch the Fall Ignite presentation
Already know? This webinar summarizes what's new in Sentinel in the past six months (Apr-Sept 21).
Get deeper? Watch the Webinar: MP4YouTube, Presentation

 

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

 

If you want to get an initial overview of Microsoft Sentinel's technical capabilities, the latest Ignite presentation is a good starting point. You might also find the Quick Start Guide to Microsoft Sentinel useful (requires registration). A more detailed overview, however somewhat dated, can be found in this webinar: MP4YouTube, Presentation.

 

Lastly, want to try it yourself? The Microsoft Sentinel All-In-One Accelerator  (blog, Youtube, MP4, deck) presents an easy way to get you started. To learn how to start yourself, review the onboarding documentation, or watch Insight's Sentinel setup and configuration video.

 

Learn from users

Thousands of organizations and service providers are using Microsoft Sentinel. As usual with security products, most do not go public about that. Still, there are some.

 

Learn from Analysts

 

Module 2: How is Microsoft Sentinel used?

 

Short on time? Read this presentation.

 

Many users use Microsoft Sentinel as their primary SIEM. Most of the modules in this course cover this use case. In this module, we present a few additional ways to use Microsoft Sentinel.

 

As part of the Microsoft Security stack

Use Sentinel, Azure Defender, Microsoft 365 Defender  in tandem to protect your Microsoft workloads, including Windows, Azure, and Office:

 

To monitor your multi-cloud workloads

The cloud is (still) new and often not monitored as extensively as on-prem workloads. Read this presentation to learn how Microsoft Sentinel can help you close the cloud monitoring gap across your clouds.

 

Side by side with your existing SIEM

Either for a transition period or a longer term, if you are using Microsoft Sentinel for your cloud workloads, you may be using Microsoft Sentinel alongside your existing SIEM. You might also be using both with a ticketing system such as Service Now. 

 

For more information on migrating from another SIEM to Microsoft Sentinel, watch the migration webinar: MP4YouTubeDeck.

 

There are three common scenarios for side by side deployment:

You can also send the alerts from Microsoft Sentinel to your 3rd party SIEM or ticketing system using the Graph Security API , which is simpler but would not enable sending additional data. 

 

For MSSPs

Since it eliminates the setup cost and is location agnostics, Microsoft Sentinel is a popular choice for providing SIEM as a service. You can find a list of MISA (Microsoft Intelligent Security Association) member MSSPs using Microsoft Sentinel. Many other MSSPs, especially regional and smaller ones, use Microsoft Sentinel but are not MISA members.

 

To start your journey as an MSSP, you should read the Microsoft Sentinel Technical Playbooks for MSSPs. More information about MSSP support is included in the next module, cloud architecture and multi-tenant support.  

 

Part 2: Architecting & Deploying

 

While the previous section offers options to start using Microsoft Sentinel in a matter of minutes, before you start a production deployment, you need to plan. This section walks you through the areas that you need to consider when architecting your solution, as well as provides guidelines on how to implement your design:

  • Workspace and tenant architecture
  • Data collection 
  • Log management
  • Threat Intelligence acquisition

 

Module 3: Workspace and tenant architecture

 

Short on time? Watch the Nic DiCola's Ignite presentation (first 11 Minutes)
Get Deeper? Watch the Webinar: MP4YouTubePresentation

 

A Microsoft Sentinel instance is called a workspace. The workspace is the same as a Log Analytics workspace and supports any Log Analytics capability. You can think of Sentinel as a solution that adds SIEM features on top of a Log Analytics workspace.

 

Multiple workspaces are often necessary and can act together as a single Microsoft Sentinel system. A special use case is providing service using Microsoft Sentinel, for example, by an MSSP (Managed Security Service Provider) or by a Global SOC in a large organization. 

 

To learn more about why use multiple workspaces and use them as one Microsoft Sentinel system, read Extend Microsoft Sentinel across workspaces and tenants or, if you prefer, the Webinar version: MP4YouTubePresentation.

 

There are a few specific areas that require your consideration when using multiple workspaces:

 

 

The Microsoft Sentinel Technical Playbook for MSSPs provides detailed guidelines for many of those topics, and is useful also for large organizations, not just to MSSPs.

 

Module 4: Data collection

 

Sept 2021 update: our latest webinar on data collection scenarios by Edi Lahav and Yaniv 
Shasha. YouTube, MP4, Deck

The foundation of a SIEM is collecting telemetry: events, alerts, and contextual enrichment information such as Threat Intelligence, vulnerability data, and asset information. You can find a list of sources you can connect here:

  • Documentation of the connectors which are part of the connectors gallery.
  • The Grand List of sources you can connect to Microsoft Sentinel, whether part of the gallery or not (note: this list is no longer being updated).

 

How you connect each source falls into several categories or source types. Each source type has a distinct setup effort but once deployed,  it serves all sources of that type. The Grand List specifies for each source what its type is. To learn more about those categories, watch the Webinar (includes Module 3): YouTube, MP4Deck.

 

The types are:

 

  • Built-in service-to-service connectors allow Microsoft Sentinel to connect directly to cloud services such as Office 365 or AWS CloudTrail. Some of the service-to-service connectors, such as AAD, utilize Azure diagnostics behind the scenes. 

 

  • Direct refers to sources that natively know how to send data to Microsoft Sentinel or Log Analytics. These include Azure services or other Microsoft solutions that support sending telemetry (often referred to as "diagnostics") to Log Analytics and 3rd party sources that use the ingestion API to write to Log analytics or Microsoft Sentinel directly. The Microsoft direct sources are listed in addition to the Grand List and in the blog post "Collecting logs from Microsoft Services and Applications."

 

  • The Log Forwarder is a VM that enables collecting Syslog and CEF events from remote systems. If a source is listed in the Grand List as CEF or Syslog, you will use the Log Forwarder to collect from it. Learn more about the Log Forwarder in this webinar (plus a bonus: learn how to use it to filter events):  YouTubeMP4Deck.

 

  • The Log Analytics agent collects information from Windows or Linux hosts. In addition to OS events such as Windows Events, the agent can collect events stored in files. Learn more about the Log Analytics agent in this blog: collecting telemetry from on-prem and IaaS server using the Log Analytics agent. The Azure Monitor Agent is a new generation agent currently in preview that offers advantages such as Windows events filtering. The Log Analytics agent is being deprecated on 31 August 2024, so if you have not yet deployed the Log Analytics agent you should consider whether it is possible for you to start using the Azure Monitor Agent (see next bullet point).

 

  • The Azure Monitor Agent (AMA) is the replacement for the Log Analytics Agent. The Azure Monitor agent introduces several new capabilities not available in the Log Analytics agent such as filtering, scoping, and multi-homing. At the time of writing this update, AMA isn't yet at parity with the Log Analytics agent, although this will change over time. Consider whether the features you need for your Microsoft Sentinel deployment are supported in AMA, or whether to continue to use the Log Analytics agent for now and migrate at a later date. You can sign up for the Everything You Ever Wanted to Know About Using the New Azure Monitor Agent (AMA) with Microsoft Sentinel on Nov 22 here.

 

 

  • Integrate Threat Intelligence (TI) sources using the built-in connectors from TAXII servers or Microsoft Graph Security API. Read more on how to in the documentation. TI can also be important as a custom log using a custom connector or as a lookup table. You can read more about how TI is used managed in Microsoft Sentinel in the TI modules later. 

 

If your source is not available, you can create a custom connector. Custom connectors use the ingestion API and therefore are similar to direct sources. Custom connectors are most often implemented using Logic Apps, offering a codeless option, or Azure Functions.

 

Module 5: Log Management

 

While how many and which workspaces to use is the first architecture question to ask, there are additional log management architectural decisions:

  • Where and how long to retain data.
  • How to best manage access to data and secure it. 

 

Retention

 

Logs Security

 

Dedicated cluster

 

Module 6: Enrichment: TI, Watchlists, and more

 

One of the important functions of a SIEM is to apply contextual information to the event steam, enabling detection, alert prioritization, and incident investigation. Contextual information includes, for example, threat intelligence, IP intelligence, host and user information, and watchlists.

 

Microsoft Sentinel provides comprehensive tools to import, manage, and use threat intelligence. For other types of contextual information, Microsoft Sentinel provides Watchlists, as well as alternative solutions.

Threat Intelligence

 

Sept 2021 update: Watch the Explore the Power of Threat Intelligence in Microsoft Sentinel
webinar.
YouTube, MP4, Deck.

Threat Intelligence is an important building block of a SIEM.

 

In Microsoft Sentinel, you can integrate threat intelligence (TI) using the built-in connectors from TAXII servers or through the Microsoft Graph Security API. Read more on how to in the documentation. Refer to the data collection modules for more information about importing Threat Intelligence. 

 

Once imported, Threat Intelligence is used extensively throughout Microsoft Sentinel and is weaved into the different modules. The following features focus on using Threat Intelligence:

 

Watchlists and other lookup mechanisms

 
To import and manage any type of contextual information, Microsoft Sentinel provides Watchlists, which enable you to upload data tables in CSV format and use them in your KQL queries. Read more about Watchlists in the documentation
 
In addition to Watchlists, you can also use the KQL externaldata operator, custom logs, and KQL functions to manage and query context information. Each one of the four methods has its pros and cons, and you can read more about the comparison between those options in the blog post "Implementing Lookups in Microsoft Sentinel." While each method is different, using the resulting information in your queries is similar enabling easy switching between them.
 
Read utilize Watchlists to Drive Efficiency During Microsoft Sentinel Investigations for ideas on using Watchlist outside of analytic rules.
 

Module X: Migration

 

Watch the Webinar: YouTubeMP4Presentation

 

In many (if not most) cases, you already have a SIEM and need to migrate to Microsoft Sentinel. While it may be a good time to start over and rethink your SIEM implementation, it makes sense to utilize some of the assets you already built in your current implementation. To start watch our webinar describing best practices for converting detection rules from Splunk, QRadar, and ArcSight to Azure Sentinel Rules: YouTubeMP4Presentation, blog.

Watch the Deep Dive into Microsoft Sentinel Normalizing Parsers and Normalized
Content webinar:
YouTube, MP3, Presentation

Watch the Turbocharging ASIM: Making Sure Normalization Helps Performance Rather Than
Impacting It webinar: YouTube, MP4, Deck.

 

Working with various data types and tables together presents a challenge. You must become familiar with many different data types and schemas, write and use a unique set of analytics rules, workbooks, and hunting queries for each, even for those that share commonalities (for example, DNS servers). Correlation between the different data types necessary for investigation and hunting is also tricky.

 

The Azure Sentinel Information Model (ASIM) provides a seamless experience for handling various sources in uniform, normalized views. ASIM aligns with the Open-Source Security Events Metadata (OSSEM) common information model, promoting vendor agnostic, industry-wide normalization.

 

The current implementation is based on query time normalization using KQL functions. And includes the following:

  • Normalized schemas cover standard sets of predictable event types that are easy to work with and build unified capabilities. The schema defines which fields should represent an event, a normalized column naming convention, and a standard format for the field values.
  • Parsers map existing data to the normalized schemas. Parsers are implemented using KQL functions.
  • Content for each normalized schema includes analytics rules, workbooks, hunting queries, and additional content. This content works on any normalized data without the need to create source-specific content.

 

Using ASIM provides the following benefits:

  • Cross source detection: Normalized analytic rules work across sources, on-prem and cloud, now detecting attacks such as brute force or impossible travel across systems including Okta, AWS, and Azure.
  • Allows source agnostic content: the coverage of built-in as well as custom content using ASIM automatically expands to any source that supports ASIM, even if the source was added after the content was created. For example, process event analytics support any source that a customer may use to bring in the data, including Defender for Endpoint, Windows Events, and Sysmon. We are ready to add Sysmon for Linux and WEF once released!
  • Support for your custom sources in built-in analytics
  • Ease of use: once an analyst learns ASIM, writing queries is much simpler as the field names are always the same.

 

To learn more about ASIM:

 

To Deploy ASIM:

  • Deploy the parsers from the folders starting with “ASIM*” in the parsers folder on GitHub.
  • Activate analytic rules that use ASIM. Search for “normal” in the template gallery to find some of them. To get the full list use this GitHub search.

 

To Use ASIM:

 

Part 3: Creating Content

 

What is Microsoft Sentinel's content?

 

Microsoft Sentinel security value is a combination of its built-in capabilities such as UEBA, Machine Learning, or out-of-the-box analytics rules and your capability to create custom capabilities and customize built-in ones. Customized SIEM capabilities are often referred to as "content" and include analytic rules, hunting queries, workbooks, playbooks, and more.

 

In this section, we grouped the modules that help you learn how to create such content or modify built-in-content to your needs.  We start with KQL, the Lingua Franca of Azure Sentinel. The following modules discuss one of the content building blocks such as rules, playbooks, and workbooks. We wrap up by discussing use cases, which encompass elements of different types to address specific security goals such as threat detection, hunting, or governance. 

 

Module 7: KQL

 

Short on time? Start at the beginning and go as far as time allows.

 

Most Microsoft Sentinel capabilities use KQL or Kusto Query Language. When you search in your logs, write rules, create hunting queries, or design workbooks, you use KQL.  Note that the next section on writing rules explains how to use KQL in the specific context of SIEM rules.

 

We suggest you follow this Sentinel KQL journey:

  1. Pluralsight KQL course - the basics
  2. The Microsoft Sentinel KQL Lab: An interactive lab teaching KQL focusing on what you need for Microsoft Sentinel:
    1. Learning module (SC-200 part 4)

Module 8: Analytics

 

Writing Scheduled Analytics Rules

 

Short on time? watch the Webinar: MP4YouTubePresentation

 

Microsoft Sentinel enables you to use built-in rule templates, customize the templates for your environment, or create custom rules. The core of the rules is a KQL query; however, there is much more than that to configure in a rule.

 

To learn the procedure for creating rules, read the documentation. To learn how to write rules, i.e., what should go into a rule, focusing on KQL for rules, watch the webinar: MP4, YouTube, Presentation.

 

SIEM rules have specific patterns. Learn how to implement rules and write KQL for those patterns:  

 

To blog post "Blob and File Storage Investigations" provides a step by step example of writing a useful analytic rule.

 

Using built-in analytics

Before embarking on your own rule writing, you should take advantage of the built-in analytics capabilities. Those do not require much from you, but it is worthwhile learning about them:

 

Module 9: Implementing SOAR

 

Sept 2021 update: Watch the What’s New in Microsoft Sentinel Automation webinar: 
YouTubeMP4, Deck

 

In modern SIEMs such as Microsoft Sentinel, SOAR (Security Orchestration, Automation, and Response) comprises the entire process from the moment an incident is triggered and until it is resolved. This process starts with an incident investigation and continues with an automated response. The blog post "How to use Microsoft Sentinel for Incident Response, Orchestration and Automation" provides an overview of common use cases for SOAR.

 

Automation rules are the starting point for Microsoft Sentinel automation. They provide a lightweight method for central automated handling of incidents, including suppression, false-positive handling, and automatic assignment.

 

To provide robust workflow based automation capabilities, automation rules use Logic App playbooks:

You can find dozens of useful Playbooks in the Playbooks folder on the Microsoft Sentinel GitHub, or read "A playbook using a watchlist to Inform a subscription owner about an alert" for a Playbook walkthrough.

 

While Microsoft Sentinel is a cloud-native SIEM, its automation capabilities do extend to on-prem environments, either using the Logic Apps on-prem gateway or using Azure Automation as described in "Automatically disable On-prem AD User using a Playbook triggered in Azure"

 

Module 10: Workbooks, reporting, and visualization

 

Short on time? Watch the Webinar: YouTubeMP4Deck

 

Workbooks

 

As the nerve center of your SOC, you need Microsoft Sentinel to visualize the information it collects and produces. Use workbooks to visualize data in Microsoft Sentinel.

 

Workbooks can be interactive and enable much more than just charting. With Workbooks, you can create apps or extension modules for Microsoft Sentinel to complement built-in functionality. We also use workbooks to extend the features of Microsoft Sentinel. Few examples of such apps you can both use and learn from are:

You can find dozens of workbooks in the Workbooks folder in the Microsoft Sentinel GitHub. Some of those are available in the Microsoft Sentinel workbooks gallery and some are not. 

 

Reporting and other visualization options

 

Workbooks can serve for reporting. For more advanced reporting capabilities such as reports scheduling and distribution or pivot tables, you might want to use:

You might also want to read the documentation article on incident investigation. As part of the investigation, you will also use the entity pages to get more information about entities related to your incident or identified as part of your investigation.

 

Incident investigation in Microsoft Sentinel extends beyond the core incident investigation functionality. We can build additional investigation tools using Workbooks and Notebooks (the latter are discussed later, under hunting). You can also build additional investigation tools or modify ours to your specific needs. Examples include: 

 

Module 13: Hunting

(Note that the Webinar starts with an update on new features, to learn about hunting, start at slide 12. The YouTube 
link is already set to start there)

 

While most of the discussion so far focused on detection and incident management, hunting is another important use case for Microsoft Sentinel. Hunting is a proactive search for threats rather than a reactive response to alerts. 

 

The hunting dashboard was recently refreshed in July 2021 and shows all the queries written by Microsoft's team of security analysts and any extra queries that you have created or modified. Each query provides a description of what it hunts for, and what kind of data it runs on. These templates are grouped by their various tactics - the icons on the right categorize the type of threat, such as initial access, persistence, and exfiltration. Read more about it here.

 

To understand more about what hunting is and how Microsoft Sentinel supports it, Watch the hunting intro Webinar (YouTubeMP4Deck). Note that the Webinar starts with an update on new features. To learn about hunting, start at slide 12. The YouTube link is already set to start there.

 

While the intro webinar focuses on tools, hunting is all about security. Our security research team webinar on hunting (MP4YouTubePresentation) focuses on how to actually hunt. The follow-up AWS Threat Hunting using Sentinel Webinar (MP4, YouTube, Presentation) really drives the point by showing an end-to-end hunting scenario on a high-value target environment. Lastly, you can learn how to do SolarWinds Post-Compromise Hunting with Microsoft Sentinel and WebShell hunting motivated by the latest recent vulnerabilities in on-premises Microsoft Exchange servers.
