What this book covers
Chapter 1, Active Directory Fundamentals, explains what Active Directory is and its capabilities. This chapter also explains the main components (physical and logical structure), object types, and role services of Active Directory. Last but not least, this chapter also covers why we need an advanced identity management solution such as Azure Active Directory.
Chapter 2, Active Directory Domain Services 2022, explains what we can expect with Active Directory Domain Services (AD DS) 2022 and how we can use the features introduced in AD DS 2016 (as there is no new Domain Functional Level (DFL) or Forest Functional Level (FFL) ) to improve your existing Active Directory environment.
Chapter 3, Designing an Active Directory Infrastructure, talks about what needs to be considered in Active Directory infrastructure design. This chapter discusses how to place the AD DS logical and physical components in the AD DS environment according to best practices. It also covers the design concepts for hybrid identity.
Chapter 4, Active Directory Domain Name System, explains how DNS works with AD DS. This chapter also includes information about the DNS server component, different types of DNS records, zones, DNS delegation, and DNS policies.
Chapter 5, Placing Operations Master Roles, talks about the Flexible Single Master Operations (FSMO) roles and their responsibilities. This chapter also describes things we need to consider when placing FSMO roles in an Active Directory environment.
Chapter 6, Migrating to Active Directory 2022, covers the different AD DS deployment models. This chapter also provides a step-by-step guide to migrating from an older version of AD DS to AD DS 2022.
Chapter 7, Managing Active Directory Objects, discusses how to create objects, find objects, modify objects, and remove objects (small-scale and large-scale) by using built-in Active Directory management tools and PowerShell commands.
Chapter 8, Managing Users, Groups, and Devices, further explores the Active Directory objects by deep diving into attributes, managed service accounts, and management of different object types. Last but not least, you will also learn how to sync custom attributes to Azure Active Directory.
Chapter 9, Designing the OU Structure, teaches you how to design the organizational unit (OU) structure properly, using different models to suit business requirements. This chapter also describes how to create, update, and remove OUs. Furthermore, this chapter also discusses how we can delegate AD administration by using OUs.
Chapter 10, Managing Group Policies, mainly discusses Group Policy objects and their capabilities. Group Policy processing in an AD environment depends on many different things. In this chapter, we will deep dive into group policy processing to understand the technology behind it. We are also going to look into the different methods we can use for group policy filtering. Last but not least, we will learn about most commonly use group policies.
Chapter 11, Active Directory Services – Part 01, walks us through the more advanced Active Directory topics, such as AD Lightweight Directory Services (LDS), Active Directory replication, and Active Directory sites.
Chapter 12, Active Directory Services – Part 02, sees you learn about Active Directory trusts in detail. This chapter also covers topics such as Active Directory database maintenance, Read-Only Domain Controller (RODC), AD DS backup, and recovery.
Chapter 13, Active Directory Certificate Services, discusses the planning, deployment, and maintenance of Active Directory Certificate Services. Furthermore, we will also learn how signing, encryption, and decryption work in a public key infrastructure (PKI).
Chapter 14, Active Directory Federation Services, focuses on Active Directory Federation Services (AD FS) such as planning, designing, deployment, and maintenance. This chapter also covers new features of AD FS, such as built-in Azure MFA support. At the end you will also learn how to establish a federated connection with Azure AD.
Chapter 15, Active Directory Rights Management Services, covers the Active Directory Rights Management Service (AD RMS) role, which we can use to protect sensitive data in a business. Data is the new oil, and the value of data keeps increasing. Therefore, protection of data is important for every business. In this chapter, we will learn how AD RMS works and how to configure it.
Chapter 16, Active Directory Security Best Practices, covers the protection of the Active Directory environment. Recent attacks and studies prove that adversaries are increasingly targeting identities. So, we need to be mindful of protecting our Active Directory infrastructure at any cost. In this chapter, we will learn about different tools, services, and methods we can use to protect the Active Directory environment such as Secure LDAP, Microsoft LAPS, delegated permissions, restricted RDP, and Azure AD password protection.
Chapter 17, Advanced AD Management with PowerShell, is full of PowerShell scripts that can be used to manage, secure, and audit an Active Directory environment. We will also learn about the Azure Active Directory PowerShell for Graph module, which we can use to manage, query, and update AD objects in a hybrid AD environment.
Chapter 18, Hybrid Identity, discusses how we can extend our on-prem AD DS infrastructure to Azure Active Directory. Before we work on the implementation, we will deep dive into the planning process of the Azure AD hybrid setup. In this chapter, we will also learn about different Azure AD connects deployment models, Azure AD cloud sync, Secure LDAP, and replica sets.
Chapter 19, Active Directory Audit and Monitoring, teaches you how to monitor your on-prem/hybrid AD DS infrastructure using different tools and methods (cloud based and on-prem). This chapter also demonstrates how to audit the health of an Active Directory environment.
Chapter 20, Active Directory Troubleshooting, discusses how to troubleshoot the most common Active Directory infrastructure issues using different tools and methods. Furthermore, we will also look into the most common Azure AD Connect errors, which can have a direct impact on the health of the Azure AD hybrid environment.
