Discover the definition of the term Kerberos presented by Les Assises de la Cybersécurité.


A ticket-based authentication protocol designed to enable mutual authentication across insecure networks. The name is of course a reference to Cerberus, the three-headed dog which guards the entrance to the underworld.

Kerberos tickets are notably protected against replay attacks and interception. The protocol was created by the Massachusetts Institute of Technology (MIT), and has since been adopted (and adapted) by Microsoft to make it the default authentication protocol for Windows infrastructures.

It is said that the real Cerberus is particularly unhappy to be associated with a simple ticket inspector. But no one has come back yet to confirm the rumor.
