Kerberos is a secret-key network authentication system used for encryption and authentication. Kerberos was designed to authenticate requests for network resources rather than to authenticate authorship of documents.
The system is intended to allow any two machines on a network to conduct secure and trusted communications, even when the network is known to be penetrated by intruders and neither machine has any intrinsic reason to trust the other. This system maintains passwords in a single secure host called a key-server. Because passwords are only present inside this key-server, the system is less vulnerable than if passwords were passed over the network. Individual machines make use of the key-server to authenticate users and host computers.
