A method, system and computer program for recoupling Kerberos Authentication and Authorization requests, the method including the steps of: (a) extracting authorization information, including a copy of a Ticket Granting Ticket (TGT), from an authorization request; (b) retrieving authentication information including the TGT, the authentication information having been previously extracted from an authentication transaction and stored; (c) cross-referencing the extracted authorization information with the retrieved authentication information, such that a discrepancy between the cross-referenced information invokes a security event alert.
