Hackers focus on passwords that are sent over the network.
Kerberos provides the encryption that keeps your password from being sent unprotected. Without Kerberos protection, all these methods send your unencrypted password over the network. Stanford has several software programs that use Kerberos to help protect both your email and telnet sessions from hackers. These software programs are free, and they can be downloaded and installed easily from the Web. Installing this software will make your telnet sessions secure.
