Kerberos

Kerberos is a network security package which provides a connection across a network with a high degree of resistance to security attacks.

There are two main versions of the Kerberos protocol, Kerberos 4 and Kerberos 5, which are not compatible with each other. Typically Kerberos support will be built into applications such as telnet, FTP, rlogin, rsh, &c, and one will get a kerberized version of each application if one wants to run kerberos.

Where to Get Kerberos:

  • Some operating systems (especially BSD4.4-based variants of Unix) come with Kerberos and Kerberized applications such as rlogin, rsh, &c.
  • See the official Kerberos web site at MIT.

More Information:

  • See the official Kerberos web site at MIT.
  • Another implementation particularly of interest to those outside the US is Heimdal. The same folks also have an international version of Kerberos 4

Mailing Lists and Newsgroups:

  • The comp.protocols.kerberos newsgroup is the main newsgroup for discussing kerberos. The comp.security.gss-api group may also be relevant, especially if one is kerberizing an application or protocol (the GSS-API is the preferred API and protocol binding for Kerberos 5).
