 +===== Abstract =====
 +One approach to secure systems is through the analysis of
 +audit trails. An audit trail is a record of all events that take place in
 +a system and across a network, i.e., it provides a trace of user/system
 +actions so that security events can be related to the actions of a specific
 +individual or system component. Audit trails can be inspected for the
 +presence or absence of certain patterns. This paper advocates the use of
 +process mining techniques to analyze audit trails for security violations. It
 +is shown how a specific algorithm, called the α-algorithm,​ can be used to
 +support security efforts at various levels ranging from low-level intrusion
 +detection to high-level fraud prevention.
