Kerberos Authentication Process Overview and Explainer

How does Kerberos work? This video provides an overview of Kerberos authentication and provides details related to the authentication process. Kerberos authentication is currently the default authorization technology used by Microsoft Windows, and implementations of Kerberos exist in Apple OS, FreeBSD, UNIX, and Linux. This video is organized into three sections. The first section explores the different components of Kerberos and the messages transmitted as part of a Kerberos authentication exchange are introduced. This section will give you the basics of how Kerberos works. In the second section, we examine the messages passed between components and how the different encryption keys introduced in the overview get used in practice. We look at both the initial authentication of the user and how the user then authenticates to a service. Finally, we explore two advanced topics: Kerberos Delegation and Kerberos Cross Realm authentication. You may use any of these links to jump to a specific topic.
