Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology. Kerberos is available in many commercial products as well.

The Internet is an insecure place. Many of the protocols used in the Internet do not provide any security. Tools to "sniff" passwords off of the network are in common use by malicious hackers. Thus, applications which send an unencrypted password over the network are extremely vulnerable. Worse yet, other client/server applications rely on the client program to be "honest" about the identity of the user who is using it. Other applications rely on the client to restrict its activities to those which it is allowed to do, with no other enforcement by the server.
The Internet is an unsafe place. Many protocols used in the Internet do not provide any security tools, and malicious hackers often use tools that "sniff" network passwords to "sniff" passwords. Therefore, applications that send unencrypted passwords over the network are very vulnerable. To make matters worse, other c/s applications rely on client programs to be "honest" about the identity of the user using the password. Other applications rely on the client to limit its activity to a set of allowed operations that the server has nothing else to enforce.
Some sites attempt to use firewalls to solve their network security problems. Unfortunately, firewalls assume that "the bad guys" are on the outside, which is often a very bad assumption. Most of the really damaging incidents of computer crime are carried out by insiders. Firewalls also have a significant disadvantage in that they restrict how your users can use the Internet. (After all, firewalls are simply a less extreme example of the dictum that there is nothing more secure than a computer which is not connected to the network --- and powered off!) In many places, these restrictions are simply unrealistic and unacceptable.

Most of the truly devastating incidents of computer crime are carried out by insiders. Firewalls also have a big disadvantage because they limit how users can use the Internet. (After all, a firewall is just a less extreme statement, nothing is more secure than a computer that is not connected to a network -- and of course a computer that is powered off is also safe!) In many places, these restrictions are impractical and impossible accepted.
Kerberos was created by MIT as a solution to these network security problems. The Kerberos protocol uses strong cryptography so that a client can prove its identity to a server (and vice versa) across an insecure network connection. After a client and server has used Kerberos to prove their identity, they can also encrypt all of their communications to assure privacy and data integrity as they go about their business.

Kerberos is freely available from MIT, under copyright permissions very similar those used for the BSD operating system and the X Window System. MIT provides Kerberos in source form so that anyone who wishes to use it may look over the code for themselves and assure themselves that the code is trustworthy. In addition, for those who prefer to rely on a professionally supported product, Kerberos is available as a product from many different vendors.

In summary, Kerberos is a solution to your network security problems. It provides the tools of authentication and strong cryptography over the network to help you secure your information systems across your entire enterprise. We hope you find Kerberos as useful as it has been to us. At MIT, Kerberos has been invaluable to our Information/Technology architecture.
In conclusion, Kerberos is a solution to your network security problems. It provides many authentication tools and a strong encryption system to help you keep your overall business information safe on the Internet. We hope that once you start using it, you'll find out how useful it is. At MIT, Kerberos has been highly rated by our IT architecture system.
