Join Mike Chapple for an in-depth discussion in this video Kerberos, part of CompTIA Security+ Exam Prep (SY0-401): Access Control and Identity Management.
- The Kerberos access control system is widely used to…implement authentication and authorization systems…on both UNIX and Windows platforms.…It is one of the core protocols underlying…Microsoft active directory.…Kerberos is a ticked-based authentication system…that allows users to authenticate to a centralized service…and then use tickets from that authentication process…to gain access to distributed systems…that support Kerberos authentication.…Here's how Kerberos works.…
An end user wants to gain access to a service…that supports Kerberos.…We sometimes refer to this service as a Kerberized service.…First the end user uses a Kerberos client…on his or her system to provide a user name and password.…Then client then creates a clear text authentication request…that it sends to an authentication server.…The authentication server then looks up the user…in its data base and retrieves the user's password.…It sends two messages back to the client.…
The first is a randomly generated session key…used for future communication between the client…
Author Mike Chapple, an IT leader with over 15 years experience, introduces identification methods such as usernames and biometrics, as well as authentication methods to verify users, including multifactor authentication, password authentication, and single sign-on. He also discusses authorization concepts such as mandatory and discretionary access controls, which can help you restrict access to sensitive parts of your network. The course also covers best practices for ongoing account management, such as establishing a good password policy, managing user roles, and monitoring accounts, and what to do when you need to suspend or terminate access.
