Kerberos is an authentication protocol widely used in modern Windows domain environments . In Kerberos environment, referred to as "realms", there are three basic participants: clients, service, and Key Distribution Center (KDC). Clients request access to a service and though=rough the exchange of Kerberos tickets.=, originating from KDC, they are granted access after having successfully authenticated. The KDC is responsible for both authentication and ticket granting. Attackers may attempt to abuse Kerberos by stealing tickets or forging tickets to enable unauthorized access.
