That means hackers can get unauthorized access. The development of Kerberos happened when most systems transferred unencrypted passwords. MIT developers developed Kerberos to authenticate themselves to their required systems securely. Additionally, it provides AAA security: Authentication, Authorization, and Accounting. Kerberos ensures that only authorized users can access the network resources. With these three components, Kerberos enables trusted host authentication over untrusted networks. They chose this name because the Kerberos protocol represents the following three things: It gets its name from the three-headed dog of Hades, who guarded hell in Greek Mythology. MIT developed this protocol for a project named Athena. What Does Kerberos Authentication Protocol Do? It's also an alternative authentication system to SSH, POP, and SMTP. Kerberos is used in Posix authentication, and Active Directory, NFS, and Samba. Now that we have learned what is Kerberos, let us next understand what is Kerberos used for.Īlthough Kerberos is found everywhere in the digital world, it is employed heavily on secure systems that depend on reliable auditing and authentication features. The Kerberos authentication process employs a conventional shared secret cryptography that prevents packets traveling across the network from being read or altered, as well as protecting messages from eavesdropping and replay (or playback) attacks. KDC "tickets" offer authentication to all parties, allowing nodes to verify their identity securely. Users, machines, and services that use Kerberos depend on the KDC alone, which works as a single process that provides two functions: authentication and ticket-granting. The latter functions as the trusted third-party authentication service.

Kerberos had a snake tail and a particularly bad temper and, despite one notable exception, was a very useful guardian.īut in the protocol's case, the three heads of Kerberos represent the client, the server, and the Key Distribution Center (KDC). The protocol derives its name from the legendary three-headed dog Kerberos (also known as Cerberus) from Greek myths, the canine guardian to the entrance to the underworld. The Kerberos Consortium maintains the Kerberos as an open-source project.

Microsoft rolled out its version of Kerberos in Windows 2000, and it's become the go-to protocol for websites and single sign-on implementations over different platforms. Kerberos implementations also exist for other operating systems such as Apple OS, FreeBSD, UNIX, and Linux. Initially developed by the Massachusetts Institute of Technology (MIT) for Project Athena in the late '80s, Kerberos is now the default authorization technology used by Microsoft Windows. It uses secret-key cryptography and a trusted third party for authenticating client-server applications and verifying users' identities. Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet. What is Kerberos? How Does Kerberos Work?
