Preparing for a Microsoft exam

When preparing for a Microsoft exam, there are a few things to keep in mind. First, Microsoft always provides the Skills measured section on the exam page, which will list everything in play for assessment during the exam. In this Skills measured outline, it will also give an estimate of what percentage of the exam will be about that subject. In our experience, those are usually spot on, so it's worth noting that if you're lacking in some of the bigger sections, spend more time studying and practicing in the lab on those subjects.

Another thing worth mentioning is that a lot of the sections mentioned in this Skills measured outline will align with the modules for the SC-200 learning path, so if you incorporate that into your training, you'll find it easy to ramp up in the section of the outline you're looking for. I'll talk more about the learning path modules in the next section. If you're curious about learning more outside of the module links provided on the exam page, go to https://docs.microsoft.com/en-us/learn/ and search for more topics of interest.

Generally, when I prepare for these exams, I'm looking at all resources available, whether that be the product documentation, learning path modules, or testing things out in a lab, with the lab being the most important to me, as that seems to stick out more. We'll cover setting up labs for testing in later sections.

Once you're settled on preparation for the exam, it becomes a lot clearer when considering the resources available, which we will cover in the next section. So, for now, let's focus on diving into what's laid out for us!

Introducing the resources available and accessing Microsoft Learn

When looking at training or studying resources, Microsoft does a great job of giving you structure as it pertains to the exams. The following is the list we're focusing on for resources, starting with the learning paths on the exam page:

• The learning path for the SC-200 exam: https://aka.ms/LearnSC200.
• Search for the Docs page that aligns with Skills measured: Docs.microsoft.com.
• The Microsoft Defender for Endpoint Evaluation lab: https://aka.ms/MDEEvaluation.

When looking into everything available to begin your journey toward taking the SC-200 exam, as well as learning the skills needed to be successful in your career as a SOC analyst specializing in the M365 security stack, it's important to know that it takes time. There is a lot of content for all the features available; therefore, it's beneficial to take your time to pick it all up.

For me, I always start in the order of the bullet list provided at the start of this section, and I'll explain why. I like to go through the learning paths and listen to the content laid out for me. There are some basic knowledge checks to ensure that you're getting the information down. If there are items in the modules that I'm either stuck on or just want additional information on, I start looking for the Docs page that aligns. Once I've completed the learning path, I'll start setting up a lab and essentially starting in the order outlined in the exam.

In the next sections, I will summarize some of the larger portions of the learning paths, as they're critical to ensure that you learn, for both the exam and tasks that you may encounter in your career. As for the third bullet point in the list, we'll discuss that in the next topic of this chapter after learning a little more about what the learning path has to offer!

Microsoft Defender for Endpoint

We will start with Microsoft Defender for Endpoint (MDE), Microsoft's endpoint detection and response platform. Having a basic understanding of this platform will be critical for success, which includes understanding how to create the Defender for Endpoint environment, onboard endpoints to be monitored, and configuring the various settings. So, for example, you will need to be familiar with the rights needed to access the https://securitycenter.windows.com portal for the first time and go through the wizard that guides you through your initial configuration.

Beyond setting up the tenant, you will need to know onboarding devices in your environment quite well. You will want to understand the various operating systems in your environment to ensure they are supported, addressing any down-level devices that may no longer be supported. Make notes, as there are numerous configuration differences as you move down-level, whether that be the type of onboarding method or the state of Microsoft Defender Antivirus, especially if you are running any third-party antivirus software. We will cover that in more depth later in the book.

In Figure 1.1, you can see an example of the onboarding page for MDE, where you'll select the different operating systems and deployment methods. You'll notice that as you change the OS or deployment methods, you're presented with different packages or information to help with onboarding the sensor. Along with this, a command you can run in Command Prompt to throw a test alert is available. This is really just an easy test to see that the sensor is reporting back properly:

Figure 1.1 – Endpoint onboarding

As you onboard your devices, you will want to start defining who can access what device pages and take what actions on those devices. At this point, understanding Role-Based Access Control (RBAC) will be important, as that will help ensure the various roles in your SOC have the right access to perform their job. Creating your device groups will also be extremely critical to ensure that you have the proper remediation settings for your subsets of devices, as you will be applying different auto-remediation settings to different device groups.

The last topic to familiarize yourself with during that initial tenant setup and device onboarding will be configuring the advanced features. Here, you will switch settings on and off depending on what you want to light up in the environment. These include features such as integration with Microsoft Defender for Identity, Cloud App Security, Azure Information Protection, Secure Score, and Intune.

Being able to detect, investigate, and respond to threats in your environment will be at the forefront of your thinking.

Microsoft 365 Defender

When focusing on the other aspects of Microsoft 365 Defender, you will need to know about protections such as Identity Protection within Azure AD. This means understanding how to configure Azure AD Identity Protection policies such as sign-in risk and user risk, as well as investigating and remediating risks detected by the policies you have put into place.

Another aspect of the Microsoft 365 Defender umbrella is Microsoft Defender for Office (MDO) 365, the set of protections that help safeguard your organization against malware and viruses as they come in through email or malicious links. With MDO, you will need to understand how to configure various policies such as Safe Links or Safe Attachments, as well as policies such as anti-malware, anti-phishing, and anti-spam.

Continuing down the list of capabilities within Microsoft 365 Defender, Microsoft Defender for Identity (MDI) will be especially important to know; I would say more so for real-world skills, as the exam will not go very deep into it. We will cover MDI in much more depth later in the book, as we feel it is one of the, if not the, most important security tools in the suite. For the exam though, have a good understanding of configuring the sensors on your servers, reviewing alerts in the portal, and how MDI integrates into other tools such as Microsoft Defender for Cloud Apps.

Next up is Microsoft Defender for Cloud Apps (MDCA), which we alluded to earlier in the chapter. With MDCA, you will want to have a good understanding of the cloud app security framework, how to explore apps that are discovered within Cloud Discovery, how to protect your data and apps with Conditional Access with App Control policies, classifying and protecting sensitive information, and detecting threats.

Lastly, we need to know about Data Loss Prevention (DLP) and insider risk. Being able to understand and describe the different data loss prevention components in Microsoft 365, such as investigating DLP alerts in the compliance center (a dedicated DLP dashboard), as well as within Microsoft Defender for Cloud Apps where you'll see file policy violation alerts if you have file policies created, will be necessary.

When it comes to insider risk, you will need to be able to understand and explain how to use insider risk management with the Microsoft 365 framework to prevent, detect, and contain internal risks. This will help with scenario-based questions where you need to choose solutions that meet the need. Most of these things we can do with pre-defined policy templates and insider risk policies. With those, knowing and understanding the types of actions you can take on cases within risk management cases will be good to know.

Microsoft Defender for Cloud

Microsoft Defender will be one of the lengthier sections, primarily because you need to understand a good chunk of the Azure services that can be protected. Starting with Microsoft Defender for Cloud, which will be the primary portal for Microsoft Defender for Cloud, you will learn to assess your environment and understand the resources you have that need protection. The integrations available make it quite easy to see the risk and take action to bring that workload into a protected state. Beyond connecting workloads, Azure assets, and non-Azure resources, you will need to understand remediating security alerts within Microsoft Defender for Cloud.

Microsoft Sentinel

Microsoft Sentinel is Microsoft's cloud-native Security Information and Events Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) solution. While it is new in the SIEM space, it has quickly gained much traction within the cybersecurity space due to its scalability, cost benefits as compared to traditional on-premises SIEMS (such as SPLUNK), and its quick integration capabilities to existing systems.

Microsoft Sentinel topics end up being about 20% of the SC-200 exam from a content perspective, and due to that, be prepared to cover the following topics – we will dive a bit deeper than the requirements to merely pass this section of the exam so that you are prepared to immediately apply the knowledge in your enterprise today.

Topics covered in KQL and data analysis are as follows:

• Begin understanding KQL statement structure: This will be a critical item to begin to know. The main way a Microsoft security operations analyst will begin threat hunting and creating automation will be backed by KQL.
• Begin understanding results from KQL: This will be another high-priority item to begin to know. It is one thing for a Microsoft security operations analyst to create KQL statements, but being able to confidently understand results will make or break automation and dispositions on threats.
• Begin to understand how to build multi-table statements using KQL: As we move from basic queries and basic resultant sets of data, we will take it one step further and begin sharing information on how to build multi-table statements using KQL. As a Microsoft security operations analyst, you will find this extremely useful in your day-to-day threat hunting and dashboard building.
• Begin working with data in Microsoft Sentinel using KQL: Once we have covered the preceding topics, we will move into data manipulation and management. This will be another highly necessary skill set to possess as a Microsoft security operations analyst. We will begin extracting data from structured and unstructured string fields, integrating external data, and creating parsers with functions. Soon, you will see the true power you have at your fingertips using Microsoft Sentinel as your SIEM and SOAR solution.

Topics covered in Setup and configuration are as follows:

• Create and manage Microsoft Sentinel workspaces: One of the first things the Microsoft security operations analyst will have to decide will be the overall SIEM architecture with Microsoft Sentinel. Will you use one or many workspaces to fuel the data? How will you manage RBAC? What about your cross-workspace queries? Will logging and alerting be centralized? Decentralized? We will look in depth at the options and best practices accordingly.
• Query logs in Microsoft Sentinel: As a Microsoft security operations analyst, you must be able to understand how to query data, tables, and fields that are ingested into your workspace. This will be critical for not only data discovery and investigation but also knowing where data is from a table perspective, which will allow you to granularly apply RBAC as your enterprise team members need.
• Using watchlists in Microsoft Sentinel: Learn how to create Microsoft Sentinel watchlists that are a named list of imported data. Once created, you can easily use the named watchlist in KQL queries.
• Utilize threat intelligence in Microsoft Sentinel: Learn how the Microsoft Sentinel threat intelligence page enables you to manage threat indicators.

After all this, we're left with the final topic of interest, which is KQL. This will be a staple of the threat hunting aspect within Microsoft 365.

KQL

KQL is the read-only query language that was created to work specifically with large datasets within Azure. You will need to know KQL to be successful on the threat-hunting side of things. Whether you are in the Microsoft 365 security portal or Sentinel, KQL will be needed for hunting.

We will cover the skills needed for both the exam as well as the skills needed to start your threat-hunting journey within the context of Microsoft 365. We will be covering topics such as constructing statements, analyzing the results, as well as building custom detections.

I know that's a lot of information to take in, especially if you're new to it all, but if you stay on course, then it will all come together. Getting through these topics as you work through the learning paths, with subsequent documentation article reading, setting up, and working in a demo tenant in this next section, will help write that to memory! The nice thing about it is you can always go back to a section and walk through what's being discussed within the portal. Let's dive into getting a demo tenant ready!
