Q5. Suppose an organization uses Kerberos for authentication. In terms of security and service availability, what is the effect if AS or TGS goes down?
kerberos
No it does not.

Kerberos Version 5 is standard on all versions of Windows 2000 and ensures the highest level of security to network resources. The Kerberos protocol name is based on the three- headed dog figure from Greek mythology known as Kerberos. The three heads of Kerberos comprise the Key Distribution Center (KDC), the client user and the server with the desired service to access. The KDC is installed as part of the domain controller and performs two service functions: the Authentication Service (AS) and the Ticket-Granting Service (TGS). three exchanges are involved when the client initially accesses a server resource:AS ExchangeTGS ExchangeClient/Server (CS) Exchange
You may not know it, but your network is probably unsecured right now. Anyone with the right tools could capture, manipulate, and add data between the connections you maintain with the internet. The security cat and mouse game isn't one sided, however. Network administrators are currently taking advantage of Kerberos to help combat security concerns.
This type of malware is designed to bypass the normal authentication process
"Kerberos" is a network security system, designed to prevent unauthorised access to sensitive data. The system is dependent on passwords and is used on computers operating in the Windows environment.
Physical security refers to the actual availability of getting at the equipment. This is managed by using locks and other barriers which require authentication, such as a proximity card, retinal scanner, etc. For physical security the authentication techniques must be put at the site of the equipment, such as the telecommunications closet, wiring closet, server room, and so forth. An attacker would have to be in the vicinity to try and attack the equipment. System security has to require authentication and present barriers to those from remote locations, through the network connections, web applications, and so on. Attackers in that case would not need to be in the area to try and cause problems.
The information security manager is the process owner for the development and implementation of an organization-wide information security program and ongoing activities to preserve the availability, integrity and confidentiality of information resources in compliance with applicable security policies and standards.
Best authentication and security.
