Data and identity security are very important in modern businesses. We are living in a world where identity is the new perimeter. A significant portion of this book is focused on how to use Active Directory features to secure your identity infrastructures from emerging threats. Active Directory allows you to use different authentication types, group policies, and workflows to protect the resources in your network. Even applications benefit from these technologies and methodologies to secure the identities used within applications. This helps administrators build different security rules based on departments and groups in order to protect data and workloads. It also forces individuals to follow organizational data- and network-security standards.
