Let's say that the authentication protocol used by an organization is Kerberos. If either the Authentication Server (AS) or the Ticket Granting Server (TGS) were to fail, what kind of an effect would it have on the overall level of security and availability of the service?

Describe how a challenge-response authentication system is put to use in real-world scenarios. How exactly does it make a system any less safe when it requires a password in order to access it?

Assume that the authentication mechanism used by an organization is Kerberos.What effect does the failure of either the AS (authentication server) or the TGS (ticket granting server) have on security and service availability?

Demonstrate how native authentication and authorization services are performed on the web server in response to a request from a web client for a secure server resource. Include the particulars of each step of the process. What are some of the reasons why, in your opinion, the implementation of layered protocols is such an appealing strategy? Are there any particular instances that you might use to back up the assertions you've made?

Let's imagine the mail server for your employer sends you a message alerting you that the password for your account has been changed and that you need to confirm this. In this scenario, you would need to confirm the new password. To the best of your knowledge, the password has not been changed in any way. What may have caused the requirement for the password to be changed? What systems were infected with what sort of malware, and how did the hacker get access to the information they required to properly reset the password?
