Kerberos is a network authentication protocol that has been designed to provide a robust authentication solution by employing secret key cryptography. Massachusetts Institute of Technology (MIT) has implemented a free version of this protocol, which is widely used.
Kerberos addresses the following requirements:
Kerberos makes it easy for users to log on and use the different resources on a network without having to go through the login procedure for access to each resource or service. In other words, Kerberos supports single sign-on access that would expect the user to log in only once into the system with seamless authorization to access the rest of the resources.
Distributed systems involve a large number of nodes connected to form a cluster, just like the Internet we use daily. These nodes could have malicious users that could take advantage of any flaws that exist in the network. Kerberos works well in such environments and protects the network from such users.
